Product Description
The PSV2-55T/62T/63T and PSVH-45CS Hydraulic Charge Pump Gear Pump are high-performance auxiliary pumps designed for hydraulic systems, especially for excavators and construction machinery. These charge pumps are typically mounted on the main piston pump and play a critical role in supplying stable low-pressure oil flow to ensure the proper operation of the main pump.
Low Noise & High Efficiency：Optimized gear design ensures smooth operation, low noise, and high volumetric efficiency.
Improve Main Pump Stability：Provides stable charge oil flow to maintain proper lubrication and cooling of the main pump.
Extend Hydraulic System Service Life：Reliable charge oil supply reduces wear and helps extend the lifespan of the hydraulic system.
Multiple Control Options：Compatible with different hydraulic control systems to meet various application requirements.
In modern hydraulic systems, especially in excavators and heavy construction equipment, the hydraulic charge pump plays a crucial supporting role. For models such as PSV2-55T, PSV2-62T, PSV2-63T, and PSVH-45CS, the charge pump is not just an auxiliary component—it is essential for maintaining the performance, reliability, and lifespan of the main piston pump.

RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
1.How does the variable displacement work?
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
