VCM-DF-40B/40B-10 Double Low Pressure Hydraulic Variable Vane Pump

Variable Displacement Vane Pump with Cooling circulation pump is CML Unique and patented design. First, improve machining accuracy. By sucks in heated oil from the tank and delivers it to the radiator. It effectively reduced oil temperature under a continuous process of circulation which stabilize operation conditions. Second, saving cost. Proven by tests, to combine with proper cooler, it performs a lot better cooling efficiency than cooling only from the drain port. By reducing the size of the tank (reservoir), it could save the machine space and the volume of hydraulic oil, eventually saving cost.

Feature

High Efficiency and Energy Saving: With precise machining & proper tolerance, not only the internal leakage is effectively reduced, but also the pump efficiency is greatly improved.
Less Weight & Minimized: Specially designed motor and downsized pump make the overall dimension more compact as compared with other ones with same flow rate.
Low Noise: Through special tang shaft design, the concentricity can be well secured to avoid misalignment, hence the total noise and the temperature rise will be minimized.
Durable Service Life: Special design allows the shaft to be always lubricated with hydraulic oil during operation, this substantially lower the abrasion of the pump shaft.

Application

Easy to Replace and Maintain: With same efficiency and installation interface as UVN series.
Remark: The pump displacement is the test value at 1800rpm.
