- Page 9 Operating, Installation, and Maintenance Rules for Safe Installation LOCATION OF UNIT – The pump should be installed as near to the liquid source as is practical so that the static suction head (vertical distance from the center line of the pump to water level) is maximized, and so that a short, direct suction pipe may be used.
- Page 10 Operating, Installation, and Maintenance Rules for Safe Installation (Continued) ALINGMENT PROCEDURES(continued) Check axial clearance of coupling at every 90° increment. (see figure 4) Axial clearances should be examined using a feeler gauge. Use a straight edge to check radial alignment at every 90° increment. Place the straight edge across the two rims of the sleeve coupling to check there is no light path between the edge and the coupling.
- Page 11 Operating, Installation, and Maintenance Rules for Safe Installation (Continued) PIPING - Pipes must line up and not be forced into position. Piping should be independently supported near the pump so that no strain will be placed on the pump casing. Where any noise is objectionable, pump should be insulated from the piping with vibration isolation devices.
- Page 12 Operating, Installation, and Maintenance Start and Operation STARTING – Please follow below procedure to start pump, Check if the pump-motor assembly is aligned and securely fastened to the baseplate. Check the piping is free of leakage, especially the suction piping. Connect and run auxiliary pipelines and connections, if any.
