Power Team P23 Hydraulic Hand Pump - 390cm3 Capacity Single-Speed Single-Acting

The P23 is a Power Team single-speed, single-acting hydraulic hand pump best suited for applications where there is little or no free travel. This pump has an oil reservoir capacity of 390cm3 (333cm3 usable).
Power Team hand pumps, with the angled fill port, have a built in "relief valve" oil protection system. This system is designed to protect over-pressurization of the reservoir from sudden back pressure. This system also works as a seal to prevent oil leaks. A large valve knob gives added control for slowly metering loads down.
