Pump
Size
Should be considered since it determines the frequency of pump operation. Oversize your sump when possible to keep the pump operting for longer periods, rather than constantly stopping and starting, to avoid torque vibration and possible misalignment.
Lenth

Speed
 Pumps should be specifies as short as possible and driven as slowly as possible, since the longer the pump, or the faster the RPM, the greater the radial load on the bearing surfaces.
Abrassive Conditions
Cantilever shaft, bearing-free pumps are recommended for pumping solutions containing abrasives. However, on bearing containing pumps, abrasive conditions mahy be met if a separate, clean, compatible liquid can be sued for flushing to lubricate and cool the bearings. This is especially required when more than one bearing is used.
Float
Settings
Make certain adequate liquid is above the pump's impeller to begin pumping, but low enough to prevent damage to the motor. If it is necessary to pump to a greater depth than the length of the pump, continue to pump to a level below the intake with a suction extension. However, on bearing containing pumps using a product flush to cool and lubricate the bearing(s), the pump shut-off must be set above the impeller leve to prevent the pump from continuing to run after the reservoir level has dropped too low to provide the necessary product flush for the bearing(s).
Alignment
 Although factory aligned and inspected positioning of the pump and motor should be checked initially and after periodic operating intervals to assure that misalignment has not occured, which would place undue wear on the bearing or seal ring surfaces.
Auxiliary
Pump
For standby opertion, design for the possiblity of pump operting interruptions. Employ two or more pumps for continuous or partial operation. for example, for a 100 GPM requirement, employ two pumps a 100 GPM each or three at 50 GPM each, keeping one ready for service.
