Item # P12, P Series, Single/Two Speed, Single-Acting Hydraulic Hand Pumps, 12 to 55 Cubic Inches

• Best suited for applications where there is little or no free travel.
• All metal construction won't burn through in welding environments.
• Formed metal handle provides less flex, and reduces operator fatigue.
• Convenient fill port on P23 and P55 allows pumps to be filled in a horizontal or vertical position.
• Fill cap seal acts as safety valve to prevent over-pressurizing of reservoir.
• Relief valve inboard of check valve prevents loads from drifting down.
• Large valve knob gives added control for slowly metering loads down.

Power Team hand pumps, with the angled fill port, have a built in “relief valve” 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.
