Keep the clamping length of couplings and pump shafts at least 2/3 the length of the coupling width.
Use a sufficiently rigid pump mounting base.
Set pump suction side pressure to −4 psi or more (suction port flow velocity less than 6 ft/sec).
Raise part of the drain piping so it is above the topmost part of the pump body, and insert the return section of the drain piping into the hydraulic operating fluid. Also, observe the values in the following table in order to limit the drain back pressure to 14.5 psi.
|Pump Capacity cu in/rev
|Maximum Working Pressure psi
|Pressure Adjustment Range psi
|290 to 1000 /290 to 2000 /290 to 3000
|Flow Control Limit Range gpm Note 3
|.79 to 61.8
|Revolution Speed min -1
|Fixed Discharge Pump Note 1
|Capacity cu in/rev
|3.6 to 32.3
