HDF2500 is a standalone electric pump that is both lightweight and portable. The pump, reservoir and motor are all combined into one easily handled package built around a steel frame with rubber feet. The pump is fitted with a CEJN 135 coupling outlet, a glycerine filled damped pressure gauge and an oil sight glass. It also features a fully functional remote control with a 5m cable.

HDF2500 is well suited for use in the wind turbine industry for its relatively low weight and small size. The pump is very easy to use and maintain and is equipped with an industrial inline oil filter. It has a manually adjustable pressure relief valve for easy setting of the maximum working pressure. It is also fitted with an internal pressure safety valve.

The pump is pressurised in two stages. The low pressure stage is factory set to provide a high volume oil flow for rapid piston extension and seal energising. When higher pressure is required the pump automatically switches to the high pressure, low volume mode. The high oil flow ensures the pump reaches the desired operating pressure very quickly.
