Heavy Duty S Series Rotary Gear Pump
Pressure to 300 PSI, Flow to 175 GPM, Drive Speed to 1800 RPM
Heavy Duty S Series Rotary Gear Pumps are capable of higher pressures and flow rates than the standard S-Series.
The pumps are available in cast iron (standard) and ductile iron. They are designed to operate at speeds to 1140 RPM, pressures to 300 PSI, and flow rates to 175 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 mounting.
These pumps are self-priming and unidirectional. The machining of the gears, shafts, and housing faces are held to exacting tolerances (within 0.0005″) resulting in a pump with better lift, reduced slippage, and longer service life. Standard pumps operate to 250ºF and, with modifications, to 500ºF.
Helical gears provide very smooth and quiet operation at direct motor speeds in hydraulic, lubrication and transfer applications in almost every industry classification.
