The Oilgear PVWJ-098 Variable Displacement Axial Piston Pump is designed for hydraulic systems that require power, control and durability. With a displacement of 98 cc/rev this model has a higher flow range within the PVWJ family and is suitable for medium to heavy duty hydraulic applications where more power and consistency is needed.

This pump is an open loop system and is designed to run at high speeds with stable hydraulic delivery. It can run continuous pressures in the mid-to-high PVWJ pressure range and can run for long work cycles, fluctuating loads and demanding operating conditions. Whether in industrial machines, mobile hydraulic equipment, power units or material handling systems the PVWJ-098 has the flow and efficiency for smooth hydraulic movement.

Oilgear has engineered this pump with durable internal components, hardened rotating elements and a precision machined swashplate assembly to reduce friction and enhance long term performance. The internal design allows for modern hydraulic fluids – including lower viscosity blends – to be used and the pump will still maintain its efficiency even in applications with high temperature variations or continuous duty workloads. This means less wear, less downtime and longer service life.

The PVWJ-098 has a balanced and predictable control response. It adjusts displacement smoothly and maintains flow output even when system demand changes. This is especially useful in equipment that requires controlled motion, steady hydraulic pressure and repeatable performance – such as presses, lifting systems, drilling equipment and medium to heavy actuators.

Installation flexibility adds more value. Engineers can choose from several mounting patterns, shaft configurations, rotation options and porting layouts to suit new system designs and retrofit projects. Despite having a higher displacement the pump is still compact and can fit into systems with limited installation space and still deliver robust hydraulic output.
