Centrifugal multistage pumps of ЦНС 120-…, 180-…, 240-… types

 

      Pumps of ЦНС 120-…, 180-…, 240… types are manufactured in two versions:

width="260"

  • with outboard bearing rotor supports. Oil supply is required for their lubrication (pump design «2»);
  • with built-in hard-alloy bearings, operating on transferred media (pump design «3»).

Pumps of ЦНС type (pump design «2») are designed for pumping of pure and oil field hydrogen sulphide free water into oil formations.
Pumps of design «2M» are designed for pumping of aggressive oil-field water including hydrogen sulphide water into oil formations.

Actuation is carried out by the synchronous or asynchronous motors with power from 500 to 2000 kW.
The pumps are equipped with the automatic protection and alarm system as to the main parameters.

Pumps of design «3M» are designed for pumping of aggressive oil-field water including hydrogen sulphide water into oil formations.

Actuation is carried out by the synchronous or asynchronous motors with power from 500 to 2000 kW.
The pumps are equipped with the automatic protection and alarm system as to the main parameters.
