Electric pump unit is designed to pump water, petroleum products and raw oil with kinematic viscosity of up to 300 sons (300 × 10-6 m2/c) and a temperature of minus 10 ° C to plus 80º C.S. Aggregate It is made in execution for installation in explosive and fire hazardous areas in which the class of premises B-IA and lower in accordance with the PUE (the rules for the installation of electrical installations) for pumping liquids, the pairs of which form explosive mixtures with air of category II and IIV
According to GOST R 51330.11-99 and groups T1, T2, T3, T4 according to GOST R 51330.5-99.
Depending on the density and viscosity of the pumped fluid and the requirements of the explosion - fire hazard, the pumps are equipped with different power and execution by engines, including the diesel engine
