Pump KMN 100-80-160 15 kW

Centrifugal pumps KMN cantilever monoblock single-stage are designed for pumping liquids, the vapors of which can form explosive mixtures with air, categories IIA and IIB groups T1, T2, T3, T4 according to GOST 12.1.011-78. Pumped liquids - light petroleum products, industrial alcohols and other liquids containing solid inclusions in an amount of no more than 0.01% by weight, with a particle size of no more than 0.2 mm and a kinematic viscosity of liquids of no more than 20 cSt, a density of 0.71-1.0 g / cm3, a temperature from -50 to + 45 ° C. KMN pumps are intended for operation in explosion-hazardous areas of premises of class B-1a, B-1b, B-1g, B-2a, P-I, P-II in accordance with the Electrical Installation Code and outdoor installations of class 1 and 2 according to GOST R 51330.9-99, in which explosive mixtures of flammable gases and vapors of explosion hazard category IIB according to GOST R 51330.11-99 and explosive mixture groups T2, T3 according to GOST R 51330.5-99 may be formed. Climatic version of the pump according to GOST 15150-69 UHL-1. KMN pumps are equipped with an explosion-proof electric motor of at least 1ExdIIBT4 (5) according to GOST R 51330.0-99. KMN pumps are reliable and durable. The flow part is made of corrosion-resistant aluminum alloy, which provides absolute protection against sparking even in emergency situations. The service life of the mechanical seal is increased by reducing the friction force between a pair of graphite rings of the mechanical seal by reducing the pressure of the pumped liquid in the mechanical seal chamber to 0.2 - 0.7 kg / cm2. The pumps are manufactured with a single mechanical seal and an additional cuff or double mechanical seal. The hydraulic axial force unloading system reduces the axial load on the electric motor bearings, significantly increasing the service life of the pump.
