ENERPAC P142 two-stage hydraulic hand pump 700 bar

The ENERPAC P142 is a lightweight, two-stage hand pump designed to power single-acting hydraulic cylinders. The maximum working pressure is 700 bar, and the usable oil capacity is 327 cm3. The two-stage pumping system provides a flow rate of 3,62 cm3 per stroke in the first stage and 0,90 cm3 per stroke in the second stage. Automatic stage switching allows for quick cylinder advancement until contact with the load, followed by the generation of high pressure. The compact design, locking handle, and low weight facilitate the use of the pump during assembly, service, and industrial work.

Application and technical characteristics

The ENERPAC P142 hand pump is designed to work with single-acting hydraulic cylinders and tools. It can be used for lifting, positioning, clamping, and assembly work if the required system parameters fall within the pump's capabilities. The manual drive allows the device to be used without an electrical power supply or a compressed air installation.

The two-stage pump design allows operation at two pressure ranges. The first stage, with a rated pressure of 13 bar, delivers 3,62 cm3 of oil per stroke. Once resistance increases, the system automatically switches to the second stage, enabling pressure up to 700 bar at a flow rate of 0,90 cm3 per stroke. This solution reduces the number of handle strokes needed to advance the cylinder to the load.

The pump reservoir is made of glass-reinforced nylon, while the aluminum base features a nylon shroud. These materials reduce the device's weight and ensure the structure is corrosion-resistant. The fiberglass handle is non-conductive, and the ability to lock it facilitates carrying the pump.

An internal safety valve protects the pump's hydraulic system from overload. The maximum effort required to operate the handle is 35,4 kg, and the pump piston stroke is 12,7 mm. Before connecting the device, verify the compatibility of hoses, connectors, and the cylinder regarding allowable pressure and required oil volume.

Frequently Asked Questions (FAQ)

What is the maximum pressure the ENERPAC P142 pump reaches?

The ENERPAC P142 pump generates a maximum hydraulic pressure of 700 bar. The first stage operates at a rated pressure of 13 bar, and the second stage allows for the full working pressure to be achieved.

What does the two-stage operation of the P142 pump consist of?

The first stage provides a larger volume of displaced oil, allowing for faster cylinder movement without a heavy load. After the pressure increases, the pump automatically switches to the second stage with lower displacement and higher working pressure.

Which cylinders is the P142 pump intended for?

The ENERPAC P142 is intended for single-acting hydraulic cylinders. When selecting, consider the working pressure, the required oil volume, and the compatibility of the entire system's connections.

What is the usable oil capacity of the ENERPAC P142 pump?

The usable oil volume is 327 cm3. This parameter should be compared with the oil requirement of the connected cylinder to ensure an adequate operating range.
