Marelli BB1 between bearings, axially split case with a single or double suction impeller, one stage double suction centrifugal pump

Designed for aggressive pump processes requiring robust casing and custom hydraulics.

Designed to heavy API-610 BB1 and ISO 13709 compliant standards for general refinery services, the PDH-LH pump features an axially split case with a single or double suction impeller, one stage of double suction and a centerline design for higher temperature services

  • Flows to 27,298 gpm (4,905 m³/hr)
  • Heads to 600 ft (200 m)
  • Suction Pressure 130 psi (9 bar)
  • Temperature Range -22 to 302°F (-30 to 150°C)

These precision engineered API/ISO 13709 process pumps meet rigorous engineering requirements for medium to high flow crude oil and petroleum products, pipelines and ship loading & unloading applications.

APPLICATIONS

  • Cooling water
  • Distillation
  • Sulfur recovery
  • Loading
  • Boiler feed boosting
  • Crude oil pipeline
  • Desalination
  • Water transfer

Standard Features and Benefits

  • API-610 10th 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
  • Labyrinth bearing seals to avoid external contamination and maximize seal and lubrication life
