Series Advantages
Product Advantages
1. High Pressure Capability
The Blince PVXS piston pump supports 5000 psi nominal pressure and maximum pressure up to 6090 psi, making it suitable for demanding high-pressure hydraulic systems.
2. Variable Displacement Axial Piston Design
The swashplate axial piston structure allows output flow to be adjusted according to system demand. This improves efficiency compared with a fixed displacement pump.
3. Wide Model Range
With model sizes from PVXS66 to PVXS250, the series covers displacement from 4.1 to 15.2 in³/rev, allowing users to select the right pump for different hydraulic flow requirements.
4. Strong Flow Capacity
The PVXS series provides flow from 26 to 99 US gpm at 1500 rpm and 32 to 119 US gpm at 1800 rpm, making it suitable for medium and large hydraulic systems.
5. Flexible Installation
The pump supports flange or foot mounting. Dual-unit pump versions can be installed with foot mounting, making the series suitable for customized hydraulic systems and multi-pump configurations.
6. Stable Operation in Industrial Conditions
With a filtration requirement of ISO 4406 18/15/13, hydraulic oil compatibility according to DIN 51524 Part 2, and a continuous viscosity range of 10–75 cSt, the PVXS series is suitable for professional industrial hydraulic systems.
7. High Drive Torque Capacity
Selected models support high drive torque, including up to 1233 lb·ft for PVXS250, making the pump suitable for heavy-duty hydraulic power transmission.
8. Suitable for Energy-Saving Hydraulic Systems
The variable displacement design helps reduce unnecessary flow output, improving energy efficiency and reducing oil temperature in systems with changing load demands.
