Nachi PZ-6B-125-180E3A-20 Pump

Startup Precautions: Check to make sure that the rotation direction of the pump is the same as the rotation direction indicated by the arrow on the pump body. Air entering the pump or pipes can cause noise or vibration. At startup, set the pump discharge side to a no-load state, and operate the pump in the inching mode to remove any air that might be in the pump or pipes. To enable superior pressure and flow control, loosen the air vent when starting up the pump in order to release any air, and fill the inside of the solenoid with … Read more

Nachi PZ-6B-100-180E2A-20 Pump

Fluid: Provide a suction strainer with a filtering grade of about 100μ (150 mesh). Provide a return line filter of grade 10μm or less on the return line to the tank. (When the pump is used at a high pressure of 2000 psi or greater, a filter of 10μm or less is recommended.) Manage hydraulic operating fluid so contamination is maintained at class NAS10 or lower. Use hydraulic operating fluid when the operating ambient temperature is in the range of 32 to 140°F.

Nachi PZ-6B-80-180E1A-20 Pump

Fluid: Use only good-quality hydraulic operating fluid with a kinematic viscosity during operation within the range of 20 to 200 centistokes. Normally, you should use an R&O type and wear-resistant type of ISOGV32 to 68 or equivalent. The optimum kinematic viscosity during operation is 20 to 50 centistokes. The operating temperature range is 41 to 140°F. When the oil temperature at startup is 41°F or less, run the pump at low pressure until the oil temperature reaches 40°F. Provide a suction strainer with a filtering grade of about 100μ (150 mesh). Provide a return line filter of grade 10μm or … Read more

Nachi PZ-5B-64-130E3A-11 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 in order to limit the drain back pressure to 14.5 psi. Model No. PZ-5B-64-130E3A-11 Pump Capacity cu … Read more

Nachi PZ-5B-40-130E1A-11 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 in order to release any air, and fill the inside of the solenoid with hydraulic operating fluid. You can change the position of the air vent by rotating its cover.

Nachi PZ-4B-32-100E3A-11 Pump

Handling: Before adjusting the manual adjusting screw from the first time or when there is no input current to the valve due to electrical malfunction or some other reason, you can control pump pressure and flow rate by rotating the manual adjusting screw. Normally, the manual adjusting screw should be returned completely to its original position and secured with the lock nut.
