(*) The material of pumps differ according to the type of pumped liquid, operating temperature and pressure. Contact our company for detailed information
Design Features: 
  • API 610 11th Ed.-OH2 centerline-mounted design providing high reliability, temperature endurance and life
  • Horizontal, single stage, radially split voluts casing type, end suction centrifugal pumps with closed impeller.
  • Due to the back-pull-out design, the complete bearing assembly including impeller and shaft can be dismantled without removing the volute casing from the piping system.
  • All impellers are dynamically balanced according to ISO 1940 class 2.5
  • Axial thrust is balanced in closed impeller by wear ring I balance hole system.
  • Heavy duty shaft not in contact with the medium handled (dry shaft).
  • For casing sealing, confined gaskets are used to prevent blow-out under pressure.
  • Pump shaft Is supported by oil lubricated, long-life, heavy duty rolling bearings. On the coupling side two angular contact ball bearings and on impeller side cylindrical roller bearing or ball bearing Is used.
  • Bearing isolators to prevent leakage into the bearings.
  • High capacity oil reservoir decreases oil temperature thus increases bearing life.
  • Cooling chamber in the bearing bracket for oil oooling.
Shaft Seal: 

As per application requirements, mechanical seals according to API 682

Rotation: 

Direction of rotation is clockwise viewed from driver end.
