High Pressure Gear Pumps & Motors Series PZG Pumps Series MZG Motors Bulletin 650-Z1
High Pressure Gear Pumps and Gear Motors for today s demanding mobile and industrial applications. The PZG and MZG Series of Pumps and Motors are built to run continuously to pressures of up to 3600 PSI. Parker s new series was developed for reliable, high efficiency operation at lower noise levels than previously available. The aluminum front and rear covers are a very dense gravity casting and the center section is a high strength extrusion. This construction allows us to provide a pump and motor that can withstand the most demanding operating conditions and environments. Free moving pressure balanced bushings maintain ideal running clearances, yielding a very high operating efficiency. Volumetric efficiencies are as high as 98%. High capacity DU bushings are standard and provide long life and dependable operation. The result is a pump and motor built to exacting standards for years of trouble free service. Features Very Low Noise Operation. High Operating Pressures Up to: 3600 PSI Continuous and 4000 PSI Intermittent. Rugged Housing Assembly. Special Seal Technology. Very High Efficiencies: Volumetric Efficiency to 98% Mechanical Efficiency to 95% High Tolerance to Contamination. Long Life DU Teflon Lined Bushings. Reversible Motors are Standard. Options Application Information For maximum pump and system life, a fluid cleanliness level of ISO 16/13 is recommended. For ratings on other fluids, such as water glycols and transmission fluid, please consult factory. Intermittent operation is defined as 10% of the duty cycle with a maximum time of 5 seconds per incident. Operating fluid viscosity range is 80-1000 SSU. Maximum start-up viscosity is 4000 SSU. Fluid should have maximum anti-wear properties, rust and oxidation inhibitors. Pump inlet vacuum should not exceed 10 in. Hg. (0.35 bar) at 1800 RPM or 5 in. Hg. (0.17 bar) at pump rated speed. Maximum positive inlet pressure is 10 PSI (0.69 bar). Pump and prime mover shaft alignment must be within 0.007 inches total indicator reading. For applications with side load conditions, such as belt driven pumps, please contact the Parker. For information not specified in this brochure please contact your nearest Parker Distributor or the. Straight Keyed or Spline Shafts. Buna-N or Viton Seals. 1
