Product Overview
▔▔The Vickers PVB5 is a highly reliable inline axial piston pump designed for variable displacement hydraulic systems. Manufactured under the Eaton Vickers brand, the PVB5 series is engineered to deliver precise flow and pressure control across industrial machinery, marine systems, and mobile equipment. Operating as a variable displacement swashplate pump, it adjusts system delivery seamlessly to match dynamic load demands, minimizing energy consumption and thermal dissipation. The PVB5 series represents the core 5 US gpm capacity standard within the classic PVB lineup, providing an ideal solution for medium-pressure, high-precision hydraulic power units (HPUs) and closed-loop or open-loop auxiliary circuits.
Key Advantages
▔▔-
High-Precision Displacement Control: Integrated mechanical, hydraulic, and pressure-compensating options allow instant response to load demands, reducing continuous power loss.
Compact Inline Axial Design: Features a lightweight, space-saving swashplate configuration with optimized internal flow paths for smooth, quiet operation.
Superior Energy Efficiency: Minimizes heat generation by unloading output when pressure thresholds are reached, significantly extending hydraulic system component life.
High Operational Reliability: Precision-engineered piston-to-cylinder interfaces reduce wear, maintaining volumetric efficiency across extended service life.
Flexible Control Configuration: Supports standard pressure compensation, remote control pressure compensation, load sensing, and manual lever adjustments.

FAQ
▔▔Q1: What fluid cleanliness rating is required for optimal performance?
A: To maximize pump life and compensator responsiveness, fluid cleanliness must meet or exceed ISO 4406 rating 18/16/13. A nominal filtration rating of 10 microns is highly recommended in the return or pressure line.
Q2: Which hydraulic oil should be used with the PVB5 series?
A: Standard anti-wear hydraulic oil (HLP / HM grade) with ISO VG 32, VG 46, or VG 68 viscosity is recommended. Synthetic fluids or water-glycol fluids require special seal configurations (Viton/FKM).
Q3: Can the PVB5 pump replace older or obsolete Eaton Vickers axial piston pumps directly?
A: Yes, the PVB5 is a standard drop-in replacement for equivalent PVB series pumps of the same displacement frame size. Verify shaft dimensions, port thread types, and mounting flange details before installation.
