Purpose

Centrifugal pumps and units 20A-artesian water 18h1 (2,3,4,5,6) is designed for pumping and pumping water from underground reservoirs, and other liquids, non-corrosive to ferrous metals and rubber, with a content of solids of not more than 0 1% (by weight). Water temperature - up to 308 K (35 °C), other liquids-from 233 K to 353 K (from minus 40 to plus 80 °C).

Design

Pumping units consist of an electric motor mounted on the support body, transmission and pump parts. The pumping part - vertical centrifugal and axial intake of liquid pump. Transmission of the type A pump is a shafting with intermediate bearings connecting the pump to the motor and mounted inside the discharge pipe. Structurally transmission portion is formed in sections. compound shafts

transmission section - threaded screw.

Lubrication of bearings and transmission parts of the pump is carried out by the pumped liquid. Grease thrust bearings - oil. Thrust bearings installed in the bearing housing.

The seal pump shafts - stuffing box, on request, can be equipped with mechanical seal.
