Product Overview

▔▔

The Vickers PVB15 is an axial piston pump engineered for variable displacement operation in medium-pressure open-circuit hydraulic systems. Operating with a maximum continuous pressure rating of up to 210 bar (3050 psi) and a displacement of 21.1 cm³/rev (1.29 in³/rev), this pump serves as a high-precision flow and pressure control unit within the industry-standard Vickers PVB series.

Key Advantages

▔▔

High Volumetric and Overall Efficiency: Precision-machined piston-to-bore tolerances and optimized swashplate design minimize internal leakage and energy loss.
Low Noise Performance: Engineered valve plate timing and rigid housing structure significantly reduce operational fluid-borne and airborne noise.
Flexible Control Options: Supports pressure compensation, manual control, remote pressure control, and load-sensing functions for seamless circuit integration.
Compact & Lightweight Design: In-line swashplate design delivers exceptional power-to-weight ratio in restricted mounting spaces.
Extended Service Life: Premium bearing arrangements and hardened sliding surfaces ensure long-term durability under continuous high-pressure duty.

FAQ

▔▔

What makes the Vickers PVB15 different from gear pumps?

The PVB15 offers variable displacement and pressure compensation, meaning it only delivers the flow required by the system. This results in higher energy efficiency, lower heat generation, and longer component life compared to fixed-displacement gear pumps.

Can the PVB15 run continuously?

Yes, the Vickers PVB15 is designed for continuous-duty operation. As long as it operates within recommended limits and proper maintenance is performed, it can run reliably for long periods.
