Oilgear XD5-050 - Variable Displacement Axial Piston Pumps is designed for mobile hydraulics and tough-duty applications where compact size, strong performance and quick response is required. With a displacement of 50 cc/rev (approx.) it fits into systems where space is limited but hydraulic output is still needed. The pump is open-loop circuit design so it’s easy to integrate into a wide range of mobile and industrial hydraulic machines.

This unit is rated for continuous pressures up to 350 bar, with a maximum shaft speed of 2,700 RPM, it can deliver high flow under tough conditions. At 1,800 RPM and full displacement the nominal flow is around 22 gpm (83 l/min) – enough for many mobile equipment, off-road vehicles and hydraulic systems where flow and reliability matters.

Durability is a key feature of the XD5-050. It’s designed to run with low viscosity fluids and operate in harsh environments. Oilgear’s hard-on-hard surface technology and robust internal design increases contamination tolerance and extends service life. The pump has side or rear porting options so installation flexibility in compact chassis and tight machine layouts. Shaft and rotation can be customised for left- or right-hand rotation to aid system integration.

Control response is well managed with this pump. Drivers of mobile machinery or hydraulic systems will love how the pump reacts under load changes, thanks to its well designed displacement control and fast response behaviour. This means smooth transitions, stable flow and reliable output when demands change rapidly – for example in construction, forestry, mining or general mobile hydraulics.

Maintenance and repair is easy with the XD5-050. Because of its familiar form factor, wide support network and modular design it’s a practical choice for service providers and equipment owners alike. At Rexton Hydraulic we offer full sales, integration, repair and after-sales support for this pump model. Whether you’re replacing an existing unit or designing new hydraulics the XD5-050 is a high performance solution with proven reliability.
