Product Overview
▔▔
The VVA40 series provides an ideal solution for systems requiring variable flow at a constant pressure. By automatically adjusting its fluid output based on system demand, it prevents the energy waste and excessive heat generation common in traditional fixed-displacement pumps.
Key Advantages
▔▔
- Built-in Pressure Compensator: Automatically reduces pump displacement to zero flow when the pre-set system pressure is reached, saving significant energy.
- Low Noise Profile: Features an advanced internal vane design that ensures whisper-quiet operation, making it ideal for indoor factory floors.
- Excellent Response Time: Fast compensation response ensures stable pressure control even during sudden, heavy load changes.
- Compact Footprint: High power density allows it to deliver substantial hydraulic force while taking up minimal space in power units.

FAQ
▔▔
Q1: What does "pressure compensated" mean for the VVA40FP pump?
A: It means the pump monitors system pressure internally. When your machinery finishes a movement and holds a position, the pump automatically dials back its fluid output to near zero while holding the exact required pressure. This stops unnecessary oil from pumping, saving electricity.
Q2: Can I run this pump in a counter-clockwise (CCW) rotation?
A: No, the specific CWW20 model is factory-built exclusively for clockwise (CW) rotation. Running the pump backward will cause immediate mechanical damage to the internal vanes and cam ring due to a lack of lubrication.
