The multifluid pump is shown above configured with a 7.5 gal. reservoir and high pressure Directional Control Valve (DCV). This isolated hydraulic supply configuration is typically used to pump hydraulic fluid or HW 540, 525, 525P or similar.
The multifluid pump configuration below has the seal test valve added to the configuration. The seal test valve is a hydraulically actuated needle valve used to hold and monitor pressure when performing seal test operations.
