500 Series Rotary Gear Pump
Pressure to 1000 PSI, Flow to 60 GPM, Drive Speed to 1725 RPM
500 Series rotary gear pumps are designed to provide quiet and efficient service at standard motor speeds and moderately high pressures. Typical applications are supplying hydraulic power in machine tools and construction equipment, as well as oil field gathering line service and deep hole drilling applications.
The pumps are available in cast iron and ductile iron. They are designed to operate at speeds to 1725 RPM, pressures to 1,000 PSI, and flow rates to 60 GPM. The standard seal is a mechanical self-adjusting seal with Buna-N elastomer. Lubrication of the anti-friction bearings is accomplished by the circulation of the pumped liquid. All models are available with foot or flange mounting integral relief valves.
