PVXS Pressure Compensated Variable Displacement Vane Pump For Mining Machinery

Product Specification

PVXS Pressure Compensated Variable Displacement Vane Pump For Mining Machinery

1, Product Overview

The PVXS series is a Rexroth inclined axis variable axial piston pump, which is a benchmark product for heavy-duty, high-pressure, and high-power hydraulic systems. Renowned for its outstanding reliability, extremely high power density, and strong heavy-duty starting capability. This series of pumps is designed for open circuits and is widely used in important fields such as mining, metallurgy, shipbuilding, energy, building materials, and various large-scale engineering machinery.
The "inclined shaft" design of PVXS pump (with an angle between its drive shaft and the cylinder axis, transmitting torque through mechanisms such as universal joints) enables it to have higher displacement and torque capacity compared to inclined disc pumps, as well as longer service life under harsh working conditions.

2, Core features and advantages

. High Pressure & High Power Density:
   Capable of stable operation under continuous high pressure, the PVXS pump offers robust power output within a compact envelope, perfectly meeting the dual demands for space and power in modern heavy machinery.
. Superior Efficiency:
   Featuring an optimized piston and slipper design, low-friction bearings, and an efficient port plate configuration, the pump significantly reduces volumetric and mechanical losses. Its high overall efficiency across the entire displacement range helps to lower energy consumption and operational costs.
. Low Noise & Smooth Operation:
   Meticulous pressure ripple suppression and a robust housing design result in operating noise levels that are significantly lower than industry standards. This provides a more comfortable working environment and reduces environmental noise pollution.
. Exceptional Reliability & Long Service Life:
   Key friction pairs are treated with special materials and surface processes, offering outstanding wear resistance and shock load capacity. A robust bearing design and high-quality seals ensure an extended service life even under harsh operating conditions.
. Excellent Suction Performance:
   The optimized inlet flow path design gives the PVXS pump superior self-priming capabilities, allowing it to adapt to higher speeds and lower inlet pressures, thereby increasing system design flexibility.
. Multiple Control Options:
   A wide range of control options is available, including displacement control, pressure compensation, load sensing, and electro-hydraulic proportional control. This facilitates easy integration into various hydraulic systems for precise energy management.
