Abstract

When pumps are incorrectly installed, maintenance and operational problems will impede its performance. Careful preparation and planning is needed to ensure proper installation of all pumps. It is a coordinated effort between the supervising engineer, the mechanical and electrical contractors, and suppliers. The installation process is a series of many steps: site location, receipts and physical inspection, pre-alignment checks, location of pump foundation, design and dimensions of pump foundation, excavation and forms for pump foundation, pouring, base plate and sole plate preparation, grouting, installation of pump and driver associated piping and fittings onsite installation and commissioning of the pump set, pre-operational checks preparation for start-up, and pump in operation. Ergonomic considerations are a prime factor in the selection of a proper site. All pumps and auxiliary equipment or components should be examined upon receipt for any signs of apparent damage. The pump foundation must provide enough rigidity to absorb axial, transverse, and torsion loads that the rotating pump imposes. Once the site location, orientation, and dimensions of the pump foundation are fixed, the data can be used to mark the location, and excavate a correctly sized cavity to the correct depth. It is recommended to remove all the equipment from the base plate or sole plate prior to grouting.
