Pump type
СNS 240

Depending on the design, centrifugal sectional pumps of the CNS type and pumping units are designed to inject clean and aggressive oil-field (hydrogen sulfide-containing) water into the oil-bearing formations to maintain the deposit pressure during oil production.

CNS type pumps are horizontal centrifugal single-body pumps of sectional type with one-sided arrangement of wheels, which consist of stator and rotor parts and are equipped with sliding bearings, automatic force balancing wheel and end shaft seals.

Design features of pumps CNS 240:
head – from 1050 to 1900 m;
material of the pump flow part – wear-resistant (steel X20Cr13) or corrosion-resistant (A321);
pump rotor bearings – outer design, force -feed lubricated, or built-in, working on the pumped medium;
End seals of the rotor – mechanical seal or gland seal.
CNS pumps and units are manufactured in a common industrial design in accordance with the “Rules for electrical installations”. Climatic modification of UHL, category of installation 4 in accordance with GOST 15150.
