Tight submersible pumps of PPN

- centrifugal, tight, submersible. Are intended for pumping of neutral liquids on the basis of technical water with a density no more than 1250 kg/m ³, having firm inclusions no more than 5 mm in size which volume concentration does not exceed 10%, with a temperature from 5 to 35 °C, with rn from 6 to 8. A working environment - the ore suspension representing hydromix of particles of the processed ore with technical water and special additives. The electric pump consists of the electric motor, pump knot, system of consolidations. The electric motor of the built-in type, asynchronous, three-phase alternating current with a short-circuited rotor. The electric motor is located over pump knot and is cooled with the pumped-over environment. For transfer of the unit and its installation on the place of operation in the top part of a pump housing the earring and handles fasten. Between the electric motor and pump knot on a shaft the system of consolidations which consists of two unary face consolidations, a cuff and a dividing cavity in which oil is filled in is located. Krylchatka is made of wearproof and corrosion-resistant materials: steel 07X16H6, 40X, etc. The special wearproof polymeric covering is applied on details of flowing part of the pump. Case details of the pump are made of aluminum of the Ak9ch brand (AL4). Technical characteristics of pumps PPN.
