Hydraulic Power Unit GSE-200-45


Electric driven hydraulic power unit is integrated with hydraulic tongs of GKSH series according to GOST-3668-006-55834270-2006 specifications. Provides transformation of electric energy into pressurized flow. Explosion-proof configuration. Provides preliminary heating of a working fluid, duly start of the electric motor during cold time, supplied with devices for protection of hydro system from overloads and cooling of a working fluid at heats and its filtration. Can be used with other devices which conform to specifications of GSE-200R.

According to GOST 15150-69 specifications climatic version is UKHL1 (for moderately cold climate with ambient temperatures -45 to 50 °C).
