CNS Series Multistage Segmental
Designed for injection of water into the oil-bearing formations to boost the oil yield (to maintain the seam pressure after the natural field pressure is reduced and insufficient to bring the oil to the surface) on the oil fields.
Electrically driven horizontal, between-bearings, multistage segmental centrifugal pumps, with automatic balancing of the rotor axial thrust by balance disc and balance disc seat.
Pumps CNS … – 2 (2nd upgrading) models: CNS 45, CNS 63, CNS 90, CNS 120, CNS 180, CNS 240, CNS 315
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. As regards the mounting dimensions of their nozzles and base plate, these pumps are interchangeable with the pumps for a duty of 180 m3/h in the same service, for the replacement of which the former have been designed.
Pumps CNSz … – 2 (2nd upgrading) models:
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 CNSp… – models:
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 CNS… – 3 (3rd upgrading) models: CNS 45, CNS 63, CNS 90, CNS 120, CNS 180, CNS 240, CNS 315
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.
Pumps CNS … – 2 (2nd upgrading) models: CNS 300, CNS 360, CNS 500, CNS 630, CNS 720
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 and discharge nozzles vertically to the top. At the Customer’s request, pumps to deliver 500, 630 and 720 m3/h can be equipped with a balance disc-from-seat separation device (supplied in the CNSz configuration).
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.
Unless otherwise specified, applicable to all the constructions :
* – only the CNSp models; ** – to all the pump models except CNSp; *** – only the TsNS …-2 (2nd upgrading) models
