Key Features
-
Double vane structure advantage: Adopts advanced double vane design to reduce the force of vanes pressing against the stator inner surface, reduce wear, and improve the pump’s service life and stability under high pressure conditions.
-
High efficiency and energy saving: Volumetric efficiency up to 95% or more, effectively converting mechanical energy into hydraulic energy, reducing energy loss, and adapting to energy-saving hydraulic systems.
-
Stable and reliable operation: Concentric rotor and stator design, built-in oil trapping prevention structure, smooth operation with low noise; Wide operating temperature and viscosity range, strong adaptability to complex working conditions.
