The first HP – pump with a sound proof housing in accordance with the EU sound emission guideline was delivered.
As the sound proof housing reduces the cooling of the hydraulic oil and the electric motors an oil – air cooler was integrated in the housing. The electric motors are temperature controlled and the level of the leakage bottle is monitored by a level switch. By this an opening of the housing for inspection of these functions is not necessary. The housing is mainly made from aluminium plates and is easy to handle. It is linked to the bottom of the oil tank and can be opened to one side.
