Piston Pump Nachi PZ Series Load Sensitive Variable Piston Pump 35 to 220cm3/rev, 21 MPa.

Features
- 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. To this it adds a hydrostatic bearing mechanism, valve plate, and other noise reducing mechanism for operation that is even quieter than that of PVS Series pumps.
- The pump body houses an electrohydraulic proportional control valve, compensator, and surge cutoff valve, which eliminates the need for superfluous piping.
- The electro-hydraulic proportional control valve uses the proven, force feed back system for improved hysteresis, repeatability, and response.
- The ability to create a double pump configuration with an IP pump further expands the range of possible applications.
