Multistage Heavy Duty Axially Split Casing Centrifugal Pumps (NDS)

Horizontal axially split casing, double volute multistage design. Impellers arranged in opposed groups, MDS is a multistage single suction impeller pump for higher head, first stage double suction impeller design for low NPSH required. Removable wear rings protect the casing and impeller. The impellers are statically and dynamically balanced. The pump comply with the API610 specification latest edition in all technical details. Special antifriction bearings on both sided or sleeve bearings with ring or forced-feed lubrication (axial bearing as segmental thrust bearing).

  • Crude oil and oil product pipeline
  • Water pipelines/li>
  • Fluid injection
  • High pressure services
  • Sea water RO system

Standard material:  According to API 610 Eighth Edition, August, 1995.


Single Stage Double Suction Split Case Pumps (NSC)

The casing is axially split, which permits removal of the complete rotor without moving either piping or motor. Pumps generating high heads have double volutes to reduce radial forces. Replaceable wear ring protect the casing at the impeller running clearances. Flange drilled to ISO, DIN, BS or ANSI. The closed double suction impeller gives practically zero axial forces. Each impeller is statically and dynamically balanced according to ISO1940. Vertical or horizontal, soft packing or mechanical seal, grease or oil lubrication bearing on request.

Performance Range:
Capacity : Q up to 20000m3/hr.
Heads : H up to 200m
Temperature : T up to 1050C
Speed : n 2900/1450/980/740/580rpm, 3500/1750/1180/890/710rpm
