    4.4 Grout the baseplate Dial indicator Reference mark Separator to take up the bearing slack Figure 13: Parallel alignment 4.4 Grout the baseplate CAUTION: Do not grout until the initial alignment is made. Grout compensates for an uneven foundation. Together with the baseplate, grout makes a very rigid in- terface between the pump and the foundation by distributing the weight over the length of the base and preventing shifting.

  • Page 28: Piping Checklists

    4.5 Piping checklists It will take approximately 24 hours for the grout to harden. Check the alignment. Approximately fourteen days after the grout has been poured and the grout has completely dried, apply an oil-based paint to the exposed edges of the grout in order to prevent air and moisture from coming in contact with the grout.

Check valves In normal applications, check valves are placed in the discharge piping. Before you use a check valve in the suction piping, consider the added pressure drop to the pump, the potential of water hammer, and the chance of allowing the entire pump volute to be exposed to the discharge pressure.

    6.3 Bearing maintenance Precautions NOTICE: • Avoid equipment damage or decreased performance. Never mix greases of different con- sistencies (NLGI 1 or 3 with NLGI 2) or with different thickeners. For example, never mix a lithium-based grease with a polyurea based grease. If it is necessary to change the grease type or consistency, remove the rotor and old grease from the housing before re- greasing.
