CM Series High Pressure Vane Pump | CM-59-X, CM-38-S, CM-91-S

CM Series High-Performance Industrial High-Pressure Vane Pumps

Product Overview: The CM Series stands as a benchmark for pressure-balanced fixed displacement vane pumps in the industrial hydraulic sector, renowned for “Heavy-Duty Durability and Smooth Output.” Utilizing advanced Double Vane (Intra-Vane) technology, this series is specifically engineered to meet the rigorous demands of large-scale industrial equipment for continuous high pressure and low flow pulsation. This featured range highlights core models including CM-59-X-21/09-00, CM-38-S-21/09-00, and CM-91-S-21/11-00. Utilizing a superior radial pressure-balanced construction, the CM series maintains peak volumetric efficiency at rated pressures up to 21 MPa—serving as the definitive power core for automated heavy-duty production lines.

Key Technical Advantages:

• Heavy-Duty Double Vane Structure: The unique patented intra-vane design effectively reduces contact stress against the cam ring, drastically minimizing wear and ensuring thousands of hours of stable operation even under frequent pressure fluctuations.

• Radial Pressure Balance Technology: Symmetrical internal pressure chambers cancel out radial loads on the rotor, minimizing bearing stress and significantly enhancing reliability during extended operational cycles.

• Ultimate Silent & Low Pulsation: Precision-ground cam ring profiles ensure smooth vane movement, providing highly consistent flow output and significantly reducing hydraulic vibration and noise.

• Modular Cartridge Kit Design: Features a replaceable cartridge system. Maintenance is simplified—restore pump performance within minutes without disconnecting complex plumbing, drastically reducing downtime.

• Target Applications: Metal forming presses, scrap metal shears, metallurgical power units, die-casting machinery, and various heavy-duty industrial power stations.
