The electric flex hydraulic power pack has an 11/7.5 kW motor and the flow can be set to 20-30 l.p.m. = the perfect power pack for professional concrete sawing and drilling companies. The output is regulated by a frequency converter. This way the motor r.p.m. is adjusted to the exact oil flow required, meaning no cooling problems. The power pack needs no water cooling, which is a great advantage, especially in the winter time.
