Proven to be reliable, efficient and long-lasting, Marelli OH2 pumps provide a number of operational benefits for process engineers and plant operators:

  • API 610 11th Edition/ISO 13709 full compliance for reliability and accountability
  • Suitable with 60 Hz and 50 kW motors
  • Higher efficiencies due to a design with tangential discharge and a wide variety of hydraulics to match exact duty points
  • Centerline mounted pump casing maintains alignment during operation and elevated temperatures
  • Low suction specific speed and low NPSH characteristics with a wide choice of impellers for optimum efficiency over a large operating range
  • Finned bearing housing to provide maximum heat dissipation under API 610 compliance
  • Isolation chamber at bearing housing with a thermal barrier among mechanical seal chamber and bearing housing
  • Deflection system with fins to improve cooling
  • Labyrinth bearing seals to avoid external contamination and maximize seal and lubrication life
  • Highly maintainable and replaceable wear rings to reduce overall life cycle costs
  • Socket welded flanged drains and vents as standard (gussets and bracing also available)
  • Choice of multiple impellers in each hydraulic pump casing for optimum efficiency over a wide operating range
  • A variety of instrumentation options are available for monitoring all key operating perimeters (temperature, pressure, vibrations and more)
