These pumps have a port relief valve that produces uninterrupted activity with the circulating plate. It gives off 1200 RPM and 1000 PSi with 2000 maximum RPM. This is a single acting pump. The RPM can be raised to 2000, capacity at 27.5 GPM and 2000 PSi.

It has a bigger aspirator port in the valve. Three way valve is possible. The adjusted port relief valve is made into it at 1600 PSI and guards the cylinder. The spool is pressure balanced. It has a steel gasket so that the seal is at its optimum value for the pump to prevent leaking.

If you have an older de-tent style valve it will fit this one. The rotation of the twin shafts will allow it to go in either direction. The shaft is binary lip shaft. The mounting can be put on the side or bottom. Gear shaft reinforce the needle bearings.
