PVB10 RDY 31 H10 Vickers Eaton Variable Piston Pump 21cc 210bar

Model Number	PVB10 RDY 31 H10

Product Overview

The PVB5, PVB6, PVB10, PVB15, PVB20, PVB29 and PVB45 series are Eaton Vickers (formerly Vickers) high-pressure variable displacement axial piston pumps. Featuring a swashplate design, flow is proportional to drive speed and displacement and can be infinitely varied via pressure compensator, load sensing or manual controls. Designed for open-circuit applications, these pumps deliver high volumetric efficiency in a compact package. Specific models such as PVB10 RDY 31 H10 are fully interchangeable with original units across the entire series. Every pump undergoes 100% simulated operating condition testing to verify pressure retention, flow response and efficiency, serving as a reliable power element in high-pressure pump, motor and valve systems.

Key Technical Advantages

High-efficiency swashplate variable design: Precision-machined cylinder block, pistons and valve plate deliver high volumetric and mechanical efficiency; pressure-compensator control automatically matches system demand to minimize energy waste and heat generation.

Wide control options with rapid response: Supports pressure compensation, load sensing, adjustable displacement, handwheel or lever manual control for broad operating range and fast adaptation to varying duty cycles.

Full interchangeability and compact construction: Exact match to original Eaton Vickers dimensions, ports, shaft and control interfaces enables direct drop-in replacement of the entire PVB5–45 series without host-machine modifications; high power density saves installation space.

Long-life bearings and reliable sealing: Quality bearings and seals provide excellent contamination resistance; high recommended filtration level supports continuous high-pressure industrial and mobile operation.

Low noise and broad fluid compatibility: Quiet operation (typical full-flow noise 60–70 dB(A)); compatible with anti-wear hydraulic oil, water-glycol and other fluids to expand application flexibility.

Expert Maintenance Tips

Horizontal mounting is recommended to maintain proper case oil level; confirm rotation direction and flange alignment, pre-fill the case with oil, and avoid forced assembly that could damage the shaft or bearings.

Use clean anti-wear hydraulic oil within the manufacturer’s viscosity recommendations and appropriate filtration; fully bleed the system on first start-up to prevent cavitation and noise.

Keep case drain pressure within limits (≤0.35 bar for most models); route the drain line separately below fluid level in the reservoir; regularly check compensator settings.

Maintain control valves (C/CM/H etc.) clean and adjust strictly to factory parameters; replace seals only with genuine or certified parts.

For long-term storage maintain internal lubrication and protect against moisture; verify fluid cleanliness and viscosity before restart and never operate below the system’s minimum allowable speed.
