Oilgear PVWJ-034 Variable Displacement Axial Piston Pump is designed for hydraulic systems that need high-performance in a limited space condition. With a 33.8 cc/rev displacement, this pump is ideal for light to medium duty applications where stable flow, smooth operation and durability are required. This is perfect for industrial machines, compact mobile equipment, auxiliary circuits and systems.

The Oilgear PVWJ-034 pump comes in open loop and runs up to 3000 RPM that offers flexibility in system design and flow management. It can handle continuous pressure up to 242 bar which enable it to perform in demanding conditions. The Oilgear PVWJ-034 pump performs well under variable loads and extended use so which makes it a preferred choice for many medium duty applications.

Oilgear has designed this model with reliability in mind. The rotating group and swashplate mechanism is built with robust and wear resistant materials to support longer operation. The pump works with modern hydraulic fluids including lower viscosity options making a smooth internal lubrication and pressure range. The pump’s moderate displacement delivers efficient hydraulic flow with open circuits.

The PVWJ-034 is also known for its smooth and predictable control behavior. It responds to system demands and maintains flow transitions which is very important in applications that require accurate motion, frequent cycling and stable hydraulic output. This pump comes in compact size that allows easy installation in tight spaces, making it suitable for new hydraulic setups or retrofit projects.

At Rexton Hydraulic we supply, and provide repair services to the full PVWJ range including the PVWJ-034. Our team ensures correct model selection, professional installation support and long-term service so your hydraulic system is efficient, reliable and easy to maintain.
