Parker Hannifin, the genuine manufacture of Commercial Hydraulics, is a world leading supplier of hydraulic components proving reliability and durability for your plant and equipment through hydraulic power. The PGP/PGM 300 series products set the standard for superior performance and reliability in heavy-duty hydraulic applications. The three-piece cast iron construction with large area, low-friction bushings provide strength, high efficiency, and long life in severe operating environments. The design includes an advanced thrust plate and seal configuration, which optimizes performance even in high temperature and low viscosity conditions.
PGP 300 Series pumps are available in single, multiple, piggyback, and thru-drive assemblies. Multiple pumps reduce mounting costs, allow for a small package size and common inlet capabilities. Assemblies up to six pumping sections are available. Piggyback pumps allow the combination of pump sections of different frame size to use a common inlet in tandem configuration. The thru-drive feature allows an independent piston or gear pump to be mounted to a rear SAE drive pad. Multiple section motors are also available providing enhanced torque and speed control as well as smooth torque ripple.
Relief valve, priority valve, load-sense unloading, and other integrated or bolt-on valve options are also available.
PGP/PGM 030/050/075 Series
The Parker Hannifin PGP/PGM 30/31, 50/51 and 75/76 products are manufactured with hi-tensile grey iron. They offer a wide variety of drive shafts that are designed for high-torque applications and unique pressure balanced thrust plates contribute to optimized performance.
Units are available in single and multiple section configurations, along with various valve and Relief Valve options.
