API 610 Heavy Duty Pumps

Pumps designed to API 610-OH2 are used in heavy duty industries like Petroleum, Petrochemical, Energy, etc. for transfer of low and high density petroleum products, petrochemicals, chemicals, high temperature liquids, hot water and condensate.

Capacityup to 1000 m³/h
Headup to 160 m
Speedup to 3600 rpm
Operating Temperature-70 °C up to +350 °C *
Casing Pressure (Pmax)51 bar *
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 cooling.
