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. Learn the basics of wear components and their role in system operation in this white paper. Access holes for grouting should be provided in the skid floor plate by the OEM or packager. Methods used by the author to level and epoxy grout pump baseplates. A peristaltic pump is used for resin grouts and a diaphragm or worm pump for cement grouts. 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. 20.6 Effect of pressure grouting in unsaturated condition. Never use a vibratory device unless specifically directed by the grout manufacturer. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. High strength, rapid setting and free-flowing grouts for all types of support applications in civil engineering, general construction and industrial applications. Also, put a piece of metal under the jack screw to prevent digging into the concrete because this makes the leveling procedure very tedious. 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). Coat forms with something that will not adhere to the grout. We consider that By sloping out from the base plate you can get a little more bearing area on your pier. Doing more with less is a necessity going forward while navigating business during a pandemic. b. Did you remove the pump and driver? 3. Detailed and timely information enables performance to reach new levels. a Process Industries Practices (PIP) type baseplate. They also serve as a "tell tale" to let you know that. 2. The concrete foundation must be adequately cured before installing and grouting the base. Page 1 www.neoflux.inof 3 Pumpletter November 19, 2011 Centrifugal Pump Grouting: SUBJECT: Attaching the pump and motor base plate to the foundation. Begin the grouting process immediately after completion of the saturation process. These vent holes are absolutely necessary to expel air as the cavity fills with grout. 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 will have prepared the surface solely to prevent corrosion in the transit and storage stages. Grout manufacturers will advise the proper surface preparations and paint for their grout. Do not use oil because it can react with the grout substrate. Here are some tips for the grouting process. 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 You can sandblast the underside and then install the base immediately before corrosion occurs (less than eight hours in an ideal ambient). I acquiesce that the smaller the pump and consequential horsepower, the need for the expensive installation (foundation, baseplate and grouting) is diminished. Installation Procedures - Epoxy Grout 03 63 00 epoxy GroutinG 3-433 Construction expansion Joints 1. be spillage. 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. Many people do not properly prepare the base’s underside surface or they apply too much epoxy paint. 6. 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. Do not allow the grout to come in contact with the anchor bolts. If the paint is too thick, the epoxy grout will pull the paint off of the metal, a process known as delamination. 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. 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.
