Pumps and units Centrifugal artesian water type 24A-18x1 (2.3) are designed for pumping, as well as pumping out of buried water tanks, and other liquids that are not aggressive to ferrous metals and rubber, with the content of mechanical impurities of not more than 0.1% (according to mass). The temperature of the pumped water is up to 308 K (35 ° C), other liquids - from 233 to to 353 K (from minus 40 to plus 80 ° C).
Pumping units consist of an electric motor installed on the supporting case, the transmission and pumping parts. The pumping part is a centrifugal vertical with an axial fluid supply pump. The transmission part of type A pumps is a ripe with intermediate bearings connecting the pump with an electric motor and mounted inside the pressure pipeline. Structurally transmission part is made in the form of sections. Shaft connection
transmission sections - threaded coupling.
Lubrication of bearings of the pumping and transmission parts is carried out by pumped liquid. Lubrication of stubborn bearings - oil. Persistent bearings are installed in the support building.
