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

Applications:

  • Cooling water
  • Water supply/distribution
  • Fire protection
  • Metal manufacturing
  • Irrigation
  • General industrial services
  • Sea water

Standard material:  
Casing: Cast iron
Impeller: Cast iron
Ductile cast iron Bronze
Cast steel Brass
Stainless steel Stainless steel
Shaft: C-steel Wear ring: Cast iron
Cr-steel Brass
