with electric motor
For strip guidance systems, hydraulic power units with a rating of between 0.18 and 15 kW is usually used. For extra-heavy coilers requiring extreme capacities, power units are tailor-made to suit the application.
Standard hydraulic power units basically consist of an oil tank, a motor-driven pump assembly, control valve and filter. In the lower capacity range, constant speed pumps are used, otherwise pressure-controlled pumps with variable displacement are installed.
