-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 mecha nisms 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 feedback 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.
