NACHI PZ-5B-64-130E3A-11 Pump

PZ Series Load Sensitive Variable Piston Pump Handling: 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 to limit the drain back pressure to 14.5 psi. Model … Read more

NACHI PZ-5B-40-130E1A-11 Pump

PZ Series Load Sensitive Variable Piston Pump Handling: Equip an air bleed valve in circuits where it is difficult to release air before startup. To enable superior pressure and flow control, loosen the air vent when starting up the pump to release any air, and fill the solenoid with hydraulic operating fluid. You can change the position of the air vent by rotating its cover.
