This hydraulic powerpack is extremely compact and consists of a double stage pump and an electric motor assembled all together. The motor works in an oil bathand it is three phase at four poles. It can be supplied with double polarity and with frequency and power different from standard ones. The double stage pump consists of an extremely silent vane pump for the low pressure. Its delivery can grant a fast approach. The second stage, for high pressure, is a modular pump built with self-suction radial pistons of small dimensions. I grants deliveries from 0,8 ltr/1’ to 7,5 Ltr/1’ and standard maximal pressure till 400 bars (on demand till 800 bars) The system is controlled by a valve allowing the most suitable use of the double pump and of the motor power.
