Clark Solutions 53/55 Series Rotary Gear Pump Model 55

Series 53/55 pumps operate quietly at nominal motor speeds and discharge large volumes of liquid at medium pressures. Typical applications include hydraulic power for positioning devices, lifts, machine actuation, liquid pressurization for fuel burners and blenders as well as general transfer in all industries. The pumps are available in cast iron(standard) and ductile iron. They are designed to operate at speeds to 1725 RPM, pressures to 200 PSI, and flow rates to 51.4 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. These pumps are self-priming and uni-directional. 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 250F and, with modifications, to 500F. Helical gears provide very smooth and quiet operation at direct motor speeds in hydraulic, lubrication and transfer applications in almost every industry classification.
