TECHNICAL FEATURE
01. Cartridge-type pump core structure enables convenient on-site installation and maintenance.
02. Unique design, high-precision machining, and rational material selection collectively ensure an excellent service life.
03. The rationally designed oil supply system for vanes and vane pins ensures optimal contact between vanes and the stator, minimizing flow loss.
04. High operating pressure, large flow capacity, and simple structure.
05. Identical front and rear side plates feature symmetrical grooves and are both hydraulically balanced, ensuring uniform deformation and compensation for improved volumetric efficiency.
06. Optimized cartridge design further reduces pressure and flow pulsation as well as noise.
07. Comprehensive range of models: eight series totaling 75 specifications—including single and double pumps—to meet diverse system requirements.
