Nachi PZ Pump 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

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

Features: The electro-hydraulic proportional control valve uses the proven force feedback system for improved hysteresis, repeatabil- ity, and response. The ability to create a double pump configuration with an IP pump further expands the range of possible applications. Model No. PZ-3B-16-70E3A-11 Pump Capacity cu in/rev 4.27 Maximum Working Pressure psi 3045 Pressure Adjustment Range psi 290 to 1000/290 to 2000/290 to 3000 Flow Control Limit Range gpm Note 3 .26 to 33 Revolution Speed min -1 Min. 600 Max. 1800 Weight lbs 132 Fixed Discharge Pump  Note 1 Capacity cu in/rev 3.6 to 15.80 Pressure psi 3000 Over the years, … Read more

Features: The pump body houses an electro- hydraulic proportional control valve, compensator, and surge cutoff valve, which eliminates the need for superfluous piping. The PZ Series load sensitive variable piston pump employs the semi-cylindrical swash plate that is part of the basic technology used by the PVS series variable piston pump. Model No. PZ-2B-8-45E1A-11 Pump Capacity cu in/rev 2.74 Maximum Working Pressure psi 2030 Pressure Adjustment Range psi 290 to 2000/290 to 3000 Flow Control Limit Range gpm Note 3 .26 to 21 Revolution Speed min -1 Min. 600 Max. 2000 Weight lbs 79 Fixed Discharge Pump  Note 1 Capacity … Read more
