What Oil Does a JWI Hydraulic Pump Use?

What Oil Does a JWI Hydraulic Pump Use?
One of the most common questions we receive is, "What oil should I use in my JWI hydraulic pump?" For most JWI filter press hydraulic systems, the recommended oil is ISO 46 hydraulic oil. This hydraulic fluid provides the proper viscosity and lubrication needed for reliable operation of the hydraulic pump, hydraulic cylinder, valves, and pressure control components.
Using the correct hydraulic oil helps maintain consistent closing pressure on the filter press and extends the life of critical hydraulic components. Low oil levels, contaminated oil, or the wrong viscosity can lead to slow cylinder movement, pressure loss, excessive pump wear, and premature equipment failure.
If your filter press is struggling to maintain hydraulic pressure, it may be time to inspect your hydraulic pump and hydraulic power unit. In many cases, older systems can be upgraded with a modern JWI hydraulic pump assembly that offers improved reliability and easier maintenance. Whether you need replacement components, troubleshooting assistance, or are ready to replace your JWI hydraulic pump, our team can help identify the best solution for your specific filter press model.
