2520V Series 2520V17A51CC22R 2520V21A12-1DD22R 2520V21A12-1CC22R 2520V21A7-1AA22R Hydraulic Vane Pump

Characteristic 4520V 4535V 4525V… Series Vane Pump
* Dual-circuit Output: Two independent pump bodies share a common drive shaft, enabling simultaneous supply of two hydraulic circuits with different flow rates or pressures to meet the needs of complex hydraulic systems.
* Compact Structure: Compared with two independent pumps, the tandem pump is smaller in size, saving installation space and reducing system complexity.
* Variable Control Options: Supports variable control methods such as pressure compensation and load sensing, adjusting output according to actual load requirements to avoid energy waste.
* Multiple Displacement Combinations: Different displacement pump combinations (e.g., small displacement + large displacement) can be selected according to application requirements to optimize system performance.

Application Range of 4520V 4535V 4525V… Vane Pumps
* Construction machinery: Travel and operation systems of excavators and loaders. Tandem pumps can separately drive travel motors and working devices (e.g., boom, bucket).
* Metallurgical equipment: Hydraulic screw-down and cooling systems of rolling mills and continuous casters, with dual circuits independently controlling different functions.
* Mining machinery: Hydraulic drive for crushers and conveyors.
* Marine and offshore engineering: Hydraulic systems of steering gears and cargo winches.
