Centrifugal sectional pumps of the CNS type and pumping units, depending on the design, 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 pumps are horizontal centrifugal single-body pumps of sectional type with one-sided wheel arrangement, 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 63:

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.

Pumps of the type of central nervous system 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.

Pumps and electric pump units of the central nervous system type with a flow of 80 m3 / h and a pressure of 120 to 330 m are designed for pumping clean and contaminated water with a pH of from 6.5 to 8.5; total concentration of sulfates and chlorides up to 20 g / l, temperature up to 70 ° С, content of solids up to 1.5% by weight; particle size not more than 1 mm and microhardness not more than 1.47 GPa. Units are made in a climatic modification of UHL, category of placement 4 in accordance with GOST 15150.

Design features of the central nervous system 80 pumps:
pressure – from 1050 to 1900 m;
execution of the flow part of the pump – wear-resistant (steel 20X13) or corrosion-resistant (12X18H12M3T);
pump rotor bearings – remote, working from an oil installation, or built-in, working on a pumped medium;
end rotor seals – end or stuffing box.
The axial load on the rotor is compensated by the use of a hydraulic unloading device
