PFE series high-performance vane pumps have eight series and 75 specifications, including single pumps (PFE-31/41/51/32/42/52) and double pumps (PFED-4131/5141). The displacement range is 16.5~150m/r, the rated pressure is 21~30Mpa, and the speed range is 600~2800r/min (on this basis, our company has developed two series of single pumps, PFE-21/61, four series of double pumps, PFED-3121/4121/5121/5131, and two series of through-axle pumps, PFET-41/51, which expand the displacement range to 5~250mI/r). The pump has a unique design process and adopts an eccentric pin-type blade structure. It has a series of advantages such as high pressure, large flow, small size, stable operation, low noise, high efficiency, and long life. The main technical indicators have reached the advanced level of similar international products. PFE series vane pumps have complete varieties and specifications, excellent and reliable performance, simple and reasonable structure, and easy installation and maintenance (installation and connection conform to ISO/SAE standards). They can be widely used in machine tools, pressure die-casting machinery, engineering machinery, metallurgy, mining, light industry, chemical machinery, agricultural machinery, and various hydraulic systems.
