Find out which technologies work best to keep centrifugal pumps from causing downtime in critical industrial processes. Base frame is to be leveled on leveling plate or using jack screws to 0.02inch/ft. Conventional grouting methods for nonfilled pump baseplates are, by their very nature, labor- and time-intensive. If using shims, be sure to apply a coating (such as light grease) of some sort to ease removal. These vent holes are absolutely necessary to expel air as the cavity fills with grout. Did you remove the pump and driver? The grouting helps to reduce the vibration, deflection and noise of the whole pumping unit. If required, the base frame bottom should be painted with epoxy grout primer. Curing time for grout, especially epoxy grout, depends on the ambient temperature. They will have prepared the surface solely to prevent corrosion in the transit and storage stages. Utilizing a pregrouted baseplate with conventional grouting methods helps to minimize some of the cost, but the last pour still requires a full grout crew, skilled carpentry work, and good logistics. In order to follow standard grouting procedures, temperatures of the foundation, plates, mixing water and grout should be between 45 -90°F Cold Figure 8. Installation • Level pump, base and motor and ensure the area is free of soft foot conditions. Typically it is best to pour from one side to let the air escape from the other. This pour technique requires good flow characteristics from the grout material, and is typically only used for epoxy grout applications. This technique allowed for more precise results. Learn how early adopters are benefitting from emerging technology as well as the impact COVID-19 has had on water management. Consider using flow conditioning technology as an alternative. A conventionally grouted base plate usually requires two pours, plus additional time and manhours spent for repair-filling of any voids once the grout has cured. They also serve as a "tell tale" to let you know that. using vertical and horizontal jack bolts. Continue to check for level during the curing process. Never let rain fall on equipment during this process. Pump baseplate installation and grouting techniques covered are applicable to any turbomachinery baseplate, bed rail, or skid installation. As per AISC Design Guide 1, the compressive strength of the grout should be minimum twice the footing/pedestal ones whereas as per ACI 351.1R-99, the compressive strength of the grout should vary from 5 to 55 MPa (5000 psi to 8000 psi). Key regulations are back on the table under a new presidential administration. In fact in the grouting checklist, Chapter 5, Section 4.1 - Mounting Plate Design Verification, stainless steel is indicated as material for the leveling pads. The concrete foundation must be adequately cured before installing and grouting the base. Here are some tips for the grouting process. Laitance refers to the thin, flaky layer of hardened yet weak hydrated cement and fine sand on the top surface of concrete, usually from too much water or overworking the surface (for example, resulting from excess trowel work). However, many industries are turning towards epoxy grout due to its rapid strength development and superior material properties. Before removing the equipment, make sure it can be aligned and the base is flat and coplanar. Page 1 www.neoflux.inof 3 Pumpletter November 19, 2011 Centrifugal Pump Grouting: SUBJECT: Attaching the pump and motor base plate to the foundation. Access holes for grouting should be provided in the skid floor plate by the OEM or packager. Continue this process until all air is vented and all voids filled. Experience has taught me it is prudent to remove the shims after the process because as the shims corrode or rot they will create other issues with the foundation-to-grout joint. To prevent stress and distortion of the equipment, all surfaces in the same plane must be within 0.002″ overall. As an example, a 100-hp pump/driver set is purchased and the next step is installation. 3. In Hong Kong, soil nails are generally grouted under gravity. If the base is not designed or installed properly, the investment in the alignment process will be lost in the first moments the pump operates. Add a minimum of four ½"-diameter vent holes in each pump cavity compartment. Begin the grouting process immediately after completion of the saturation process. Coat forms with something that will not adhere to the grout. (0.17mm/m). I have added (drilled) plenty of vent holes in the base to allow for the venting process. A cast iron, Process Industry Practices (PIP) or structural steel base also has been purchased. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Place some tension on the anchor bolts relative to the base when grouting to keep the base from floating. It is acceptable to pump the grout in place with different and specific appliances for that purpose. Is it Worth It?” TAMU Paper 2004 Pump Symposium, Roger L. Jones, Charles A. Lickteig, Jean J. Zoppe, “The Road to Reliable Pumps,” TAMU Paper 2007 Pump Symposium, Todd R. Monroe, “Pump Users Handbook, Life Extension,” Heinz P. Block & Allan R. Budris. Not really compelling arguments for sure. If the site is too hot or cold, steps must be taken to change or control the situation, such as temporary insulated shelters or shade from the sun and heat. Small metal plates, preferably stainless steel, can be placed under the jack screw’s nose. Effectively communicating the specifications and procedures to the contractor increases the chance for success. A Professional’s Guide on Grouting and Concrete Repair PREFACE This handbook, the first of its kind in the industry, was originally published by FIVE STAR PRODUCTS, INC. in 1981 as an aid to owners, engineers, architects, specifiers and contractors involved in the selection, specification and use of nonshrink grouts and concrete repair materials. A range of materials suitable for pumping or traditional methods of placement for the void-free grouting of gaps of just 0.1mm to 140mm and above. Most designs require the installation of anchor bolts in the foundation that will run up and through penetrations on the baseplate. Installation Procedures - Epoxy Grout 03 63 00 epoxy GroutinG 3-433 Construction expansion Joints 1. Missed your issue of Pumps & Systems because you are not at work? Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University. Along with the concrete grouting, the foundation bolts secure the baseplate firmly to ensure vibration free pump performance. Access holes are very important when trying to flow any type of grout 10’ to 12’ across and 20’ to 30’ down the length of the foundation. High strength, rapid setting and free-flowing grouts for all types of support applications in civil engineering, general construction and industrial applications. the pump mounted on the base, but not centered on the base hold ... sequence of events for the first part of the process—foundation, leveling, grouting. How to eliminate wet well maintenance & premature wear of pumps. Base Plate Tightening after Base Level on Pads Achieved. Consider these questions: When was the last time you turned the baseplate over and prepared the surface to be grouted? It was easy if the base manufacturer designed for the use of jack screws, but even when that was not the case, they were easy to adapt and install in the field. Epoxy grouts yield superior results in most cases, while cementatious grout is less expensive. Never use a vibratory device unless specifically directed by the grout manufacturer. Wan-Huan Zhou, in Ground Improvement Case Histories, 2015. a Process Industries Practices (PIP) type baseplate. A good foundation has been designed and it is time to grout the base to the foundation. When the baseplate is level, check that all support wedges or shims are in full contact with the foundation and baseplate. Check with the manufacturer, but in most cases 4 mils (dry) is the proper amount. In the past, many installations used cementatious grout, but most companies in the last 20 to 30 years have elected to use epoxy grouts. This article does not address stilted pump bases. Manufacturers often encourage their customers to have a foundation with a mass three to five times the mass of the pump, driver and baseplate combined—even more if the pump is a positive displacement design, especially reciprocating pumps. Prudence suggests you have 10 percent more grout than the form volume—and I guarantee there will We consider that Methods used by the author to level and epoxy grout pump baseplates. Grout can also be pumped from the centre of the bearing plate where it spreads to the outside equally on all sides. Do not allow the grout to come in contact with the anchor bolts. Be aware that during the curing process, the grout can actually pull the base out of level as it shrinks. Instead, use a small, light-duty pneumatic hammer with a sharp point tip, sometimes referred to as “bush hammering.”. Try to avoid pushing or rodding the grout into place because it creates air entrainment and voids. Once the jack screws are removed, fill the resultant voids with grout or liquid epoxy. Do not use oil because it can react with the grout substrate. The sand can be topped off with caulking or tape. A common practice is to use two to three layers of paste wax. The purpose of any baseplate is to provide level, coplanar surfaces to mount the pump and driver, allowing for a proper and precise alignment between the two. The end user should specify these when purchasing. All feet are to be leveled within 0.002 Inch (0.05mm). The specific sequence is paramount. Alternatively, for large grouting areas, a grout lance is placed through the gap to the other side and withdrawn slowly as pumping proceeds. Their structural integrity is also better since no grout holes are necessary. Many believe it is to hold the base to the foundation, but the purpose is to pull the foundation, the grout and baseplate together to form one monolithic mass. The plate is held down by bolts an- chored in the concrete. With no other actions or specifications, almost no pump or base manufacturer will have the baseplate’s underside properly prepared for the grouting procedure. After some time in the field, I learned to use leveling jack screws in lieu of shims. pour hole to the point farthest away. The grout allows a little play in the as-cast foundation height as gives you space for leveling. Some companies will buy the least expensive baseplate and then lay it on the floor/ground with no further action other than to pipe up the pump and connect the electricity to the motor. Grouting Base Plates Question: "We were told by a steel erector that they typically do not remove shims from column base plates after grouting. It may be necessary to remove the protective paint supplied by the manufacturer. Keep in mind that when pouring the grout into the forms, the displaced air needs somewhere to go, and that transverse base members and braces can sometimes prevent the proper installation and venting. Cut keys to one-half the keyway length. All mounting studs shall be Type 316 stainless steel. Tighten the foundation anchor bolts evenly and double-check the level. The workability or consistency of the grout needs to match the requirements of the application. Many jobs lost will shift toward renewable energy. If using leveling jack screws, coat them with something (grease) to facilitate their removal. Hydraulic Institute on examining altitude, temperature and more when selecting a wastewater pump. The equipment (pump and driver) should be removed from the baseplate during the grouting process. c. Remove ports or fittings and check to assure Mounting holes for anchor bolts in the bases shall be drilled and not burned out and they shall not be open slots. Many end users shy away from pre-grouted pump bases or poly pump bases because of their higher initial cost, but anyone wanting a proper installation at an overall and long-term value should consider these alternative choices, especially in the National Electrical Manufacturers Association (NEMA) motor size ranges of 250 horsepower (hp) and below. In general, process pump manufacturers are asked to provide pumps as a “set” or assembled package comprising pump, driver and base plate (see figure 1). Elsey is an active member of the American Society of Mechanical Engineers, the National Association of Corrosion Engineers and the American Society for Metals. Test for moisture by using duct tape to secure a 2- or 3-foot-square piece of plastic over the foundation overnight. This is a highly recommended step. Execution of the leveling and grouting uses known techniques, but with a new twist, and are designed to shorten the pump installation and alignment time by application of a “one pour” grout procedure. a. On exterior base plates the grout keeps water from sitting in the plate/pier joint. f. Depending on the size of the application, it may be necessary to “rod” the grout with a thick chain to help the grout flow. Managing Pump Station Assets for Lowest TCO & Maximum Effectiveness, Pumping Systems: Essential Now & in the New Year, Centrifugal Pumps: The Condition Monitoring Comparison Guide, Water@Work: Emerging Technology & The 2020 Impact, Replacing Metallic Wear Components with Composites in Centrifugal Pumps, In-depth articles on pump industry issues, Expert insights into important topics in the field. I prefer the one-pour process, especially if using epoxy grout; it takes a little more preparation time because of the more sophisticated forms, but it will yield excellent results if done correctly. In the case of a new foundation, this depends on ambient conditions and on the concrete mix that was used (a five-bag mix can take as long as 28 days while a seven-bag mix may cure in a week). All grouting should be done using established procedures and recommendations of ACI for placing and curing concrete Temperature Restrictions: Grouts generally work best at 50-80°F. 2. Learn the basics of wear components and their role in system operation in this white paper. © Copyright Cahaba Media Group, Inc. All Rights Reserved. The Grout The forces and vibrations present in our rotating equipment must be absorbed by The following blog outlines the importance of grouting base plates, how to go about the grouting process, and common issues that may arise during the process. The wooden grout form now requires a top plate that forms a liquid tight seal against the bottom flange of the base plate. Pour the grout from a head box that is positioned at an elevation higher than the baseplate to provide a static head for the grout to flow. This method statement describes the step by step procedure for grouting of machine bases and base ... entire void under the base plate has been filled. A proper baseplate installation will maintain that crucial alignment—and pay off for decades with reduced maintenance costs. I would argue that it is rare to accomplish both on the same job. Some features of this site may not work without it. Jim Elsey is a mechanical engineer who has focused on rotating equipment design and applications for the military and several large original equipment manufacturers for 43 years in most industrial markets around the world. Base Plate Grouting. To read other articles in the 'Common Pumping Mistakes' column, go here. Let’s go back a minute…the driver is aligned to the driven component, Pump, Compressor, Fan, etc. Field machining of the base after completing the critical grouting process is difficult and expensive. Expansion joints are to be made of 25 mm (1 in) closed polyethylene cell foam (or equal) and placed at 1.2 to 1.8 m (2-6 ft) intervals, perpendicular to the centerline of the base plate, in accordance with API Recommended Practice 686. You will not have enough grout if you simply allow for the volume of the form. When I started in the business, we would use sets of wood or metal shims to level the base prior to grouting, leaving the shims in place. (if specified) for all horizontal pump baseplates. Anyone with pumps that operate in this manner for more than three years with no downtime for bearings, mechanical seals or couplings also has luck on their side. The plate is commonly 1 by (2 or 3) ft [300 by (600 or 900) mm] with the grout flowing in the long direction. They also informed us that they do not back off leveling nuts below the base plates during the grouting process. • Offset pump and motor shaft/coupling hub keyways by 180°. Base Grouting Process ... for the base grouting process. To start, do not assume the mechanical contractor may be the best at the pump installation process. These plates are commonly referred to as “pucks.”. Continue to inject grout using the new location. For epoxy grouts, mix the liquid first (resin and catalyst) and then add the aggregate to the liquid mix—not the other way around. Base plate grouting operations traditionally utilize cement grout. The loads from pump pedestal are transferred to baseplate and finally to grout. Do Not saturate concrete when using Conbextra epoxy resin grouts! However in Figure G-1 of Chapter 5, carbon steel is indicated the material. Elsey may be reached at jim@summitpump.com. Mixing Use a slow speed drill (appx 500rpm) with Mixer Paddle MR3, for large quantities a shear vane mixer may be used. Once the alignment target is achieved, there will be a gap between the underside of the component foot and the Mounting Plate/Base Plate or Chock Plate surface. It is acceptable to pump the grout in place with different and specific appliances for that purpose. Heinz P. Bloch, in Petrochemical Machinery Insights, 2017. the grout has moved from the 4"-diameter (min.) Grout manufacturers will advise the proper surface preparations and paint for their grout. “Grouting of Small Pump Baseplates? During the injection, cement slurry (usually prepared at some distance away from the drill holes) is normally transferred through pipes into the drill holes by an applied pumping pressure. The reasons for the use of epoxy grout in place of cheaper cementitious grout will be covered along with special baseplate preparations. More importantly, the base provides a path for the transmission of vibrations, nozzle loads and piping forces to the foundation and into the ground. Methods used by the author to level and epoxy grout pump baseplates. • Provide at least 10 diameters of straight pipe to the pump’s suction inlet. Slowly add powder to a pre-measured amount of water, ensure By sloping out from the base plate you can get a little more bearing area on your pier. Pour the grout from a head box that is positioned at an elevation higher than the baseplate to provide a static head for the grout to flow. Wait longer if moisture is visible on the underside of the plastic the next day. Only a fraction of the API pump baseplates were distorted but nearly all the ASME bases were. Start injection at one end of void and pump until grout is discharged from adjacent tap holes. If the paint is too thick, the epoxy grout will pull the paint off of the metal, a process known as delamination. A common tip is to fill the sleeves with dry sand to prevent the grout from entering that area. Without sufficient investigation—that is, with a grotesquely inaccurate, low estimate of cost to field machine—the pump manufacturer gave instructions to field machine the distorted Introduction. If installing a base on a new or existing concrete foundation, be sure to chip away the laitance at least one-half inch or, in the case of working an old foundation, until reaching stable concrete or aggregate. Try to avoid pushing or rodding the grout into place because it creates air entrainment and voids. Additionally, recommendations and specifications focus on ensuring that the baseplate is properly grouted (grouting bonds the base to the foundation). On the other hand, pre-filled or pre-grouted baseplates arrive at site already flat and aligned. You can sandblast the underside and then install the base immediately before corrosion occurs (less than eight hours in an ideal ambient). Prior to the grouting process, decide whether to use the two-pour or one-pour method. This tip reminds me of my submarine days when the specific instructions were to shut the hatch and then dive the boat. Another approach is applying the proper epoxy paint to the underside as a surface to which the grout can bond. Detailed and timely information enables performance to reach new levels. 6. 4.4.2Apparatus—The apparatus generally consists of a stiff steel plate or channel supported on shims a few inches above a rigid concrete base. be spillage. Many people do not properly prepare the base’s underside surface or they apply too much epoxy paint. By comparison, the forms used to pour a patio or driveway are probably not strong enough for this application. Execution of the leveling and grouting uses known techniques, but with a new twist, and are designed to shorten the pump installation and alignment time by application of a “one pour” grout procedure. Larger baseplates typically will best be grouted using a flowable consistency grout and formwork. b. Doing more with less is a necessity going forward while navigating business during a pandemic. I acquiesce that the smaller the pump and consequential horsepower, the need for the expensive installation (foundation, baseplate and grouting) is diminished. He is the general manager for Summit Pump Inc. and the principal of MaDDog Pump Consultants LLC. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Without the plate to provide initial grout distribution across the entire shaft base, staged grouting of ... measurements of grout pressure at the pump, and strain gages at the shaft base (1 in = 25 mm, and 1 kip = 4.4 kN). 20.6 Effect of pressure grouting in unsaturated condition.
