T-Series

The P-Series pumps can be configured in several tandem T-Series combinations. The tandem pumps can include two P-Series pumps, two P-Series pumps with an auxiliary pump, a single P-Series pump with a fixed displacement open loop gear pump, or two P-Series pumps and a gear pump coupled together as options. The T-Series provides an effective method to drive the pumps with a single input shaft and allows the option of an increased auxiliary flow and pressure source with the addition of a gear pump.

Two check valves are included in the pump end cap to control the makeup oil flow for the system. The selection of the check valves plays an important role on the system pressures, response, and the amount of heat generated. Additionally, the P-Series pumps are equipped with Shock Valves. Shock Valves are both check valves and factory preset direct acting system pressure relief valves. They are available in various relief pressure settings and bleed orifice sizes.

A screw type bypass valve is included in the pumps to permit limited unpowered movement of the machine. When opened, the bypass valve allows oil to route from one side of the closed loop circuit to the other.

The P-Series and T-Series pumps can be combined with hydraulic wheel motors or other remotely located units to complete a fluid power transmission system. The pumps are primarily used for traction drive propulsion in a wide variety of mobile applications, but are capable of many other applications.
