Centrifugal single-stage pump with a double-sided liquid entrance to the working wheel. Designed for pumping water not higher than 80 ° C, a number of chemically active liquids, as well as oil products up to 45 ° C with a kinematic viscosity of up to 25CST and a density of up to 888 kg/m 3 . -size: Medium; Text-align: Justify; " />
The hull and the pump cover are connected in the horizontal plane along the shaft axis. The flanges of the absorption and injection pipes are located on the opposite sides of the housing in the plane perpendicular relative to the axis of the shaft.
The rotor service is provided without dismantling the pump from pipe and foundation. The dimensions of the flanges meet the standard BDSen1092: 1997; DIN-EN1092: 1997; GOST 12815-80 (1996).
The pump is equipped with a lingel or end seal. Style = "Color: RGB (58, 110, 165); Font-Family: Arial, Helvetica, Sans-Serif; Font-Size: Medium; Text-align: Justify;" />
The pump tests and acceptance were carried out according to EN ISO 9906; 1999 for water from temperature 20 ° C.
The pump drive is carried out using an electric motor or internal combustion engine.
