The HP500 air-hydraulic pump is a single-acting pedal operated pump with an oil flow rate of 0,8 l/min at 500bar of working output pressure
Like all the pumps of the HP Series, it is suitable for any hydraulic application which require very high hydraulic output pressures and a moderate and controllable oil flow, to ensure the best precision during the operations.
Suitable for use in multiple applications: industrial tools, lifting systems, car repair, clamping systems, hydraulic equipment (presses, jacks, …), tire changers, bead breakers, automotive

For applications or equipments which require large oil capacities, the HP pump can be equipped with large capacity steel oil tanks (2.5 L the SL-type and 4L the XL-type)
Thanks to the choice of making the oversized oil tanks in steel rather than in the same material as the standard 1.4 liter oil tank, any possible oil leaks – from the gasket between the oil tank and the lid – due to an huge and quick return of oil were prevented.
