Electric pumping unit of "CNS" type

Electric pump units of "CNS", "CNSG", "CNSM" type are centrifugal, horizontal, sectional. They are used for pumping water with pH 7-8.5 and other liquids similar to water in density, viscosity and chemical activity, containing solid inclusions 0.1 mm in size, microhardness not more than 1.47 Gpa (14.7 kgf/cm2), the volume concentration of which does not exceed 0.1%, temperature not more than +45 ?, for "CNSG" not more than +105 ?. "CNSM" to work in the oil system of turbine generators, the working fluid - turbine oil T22 GOST 32-74, temperature from +2 to + 60 ?.
