ЦНСн, НР

Designed for creating high pressure (up to 250 bar) in various technological and production systems. They have become most widespread in systems of artificial pressure increase (PPD) during oil production in oil fields, where they are used to pump water into oil-bearing formations. They are also used to beat down scale with water at rolling mills of metallurgical plants (combinations).

CNS pumps – centrifugal, horizontal, multi-stage, single-body, sectional type; variations of constructive designs are described below.

Pumps ЦНС … – 2,

The pump rotor is carried by the oil-bath or pressure oil lubricated plain bearings. Shaft sealing: soft packed glands (C) or mechanical seals (T). The suction nozzle horizontally sideward, the discharge nozzle vertically to the top.

Pumps ЦНСз … – 2

In order to enhance a cumulative reliability and entire life of the pumps if frequently started and stopped, their design features a balance disc-from-seat separation device. It is intended for ensuring the guaranteed axial gap between the balance disc and balance disc seat.

Pumps ЦНСп …

With back-to-back impeller arrangement that makes an axial thrust balancing device unnecessary in the pump design and significantly improves the reliability of pump operation. The residual axial thrust is absorbed by a thrust bearing.

Pumps ЦНС…–3  

The pump rotor is carried by the medium-lubricated plain bearings. Shaft sealing: soft packed glands (C) or mechanical seals (T). The suction nozzle horizontally sideward, the discharge nozzle vertically to the top.

According to the dimensions of the connecting pipes and installation on the foundation (frame), all pumps of the group (ЦНС 45, ЦНС 63, ЦНС 90, ЦНС 120, ЦНС 180, ЦНС 240) are unified with pumps of the ЦНС 180 type in all relevant constructions. 

Design by materials 

Ordinary (general service) version

Handled media: clean water and oil-field produced waters free from hydrogen sulfide.

Corrosion-resistant material construction

Handled media in case of corrosion-resisting and wear- and corrosion-resisting constructions: aggressive sewage and formation oil-field produced waters including those that contain hydrogen sulfide.

Duplex steel construction

Handled media in case of duplex steel construction: aggressive sewage and formation and cenomanian oil-field produced waters including those that contain hydrogen sulfide (H2S up to 400mg/l).

The Manufacturer shall select appropriate material construction according to handled medium characteristics specified by the Purchaser.

HP, GP pumps are multistage centrifugal pumps of a new generation, designed to replace CNS and CNSp pumps. They provide interchangeability in terms of pumping technology and the size of the connection to the foundation and pipelines. Designed in accordance with the requirements of international industry standards; have improved efficiency and reliability.
