API BB1 Pumps

H2 API BB1 Pumps

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.

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
  • Highly maintainable and replaceable wear rings to reduce overall life cycle costs
  • Mechanical seal chamber API-682 3rd Edition.  Also complies to API-610 standards
  • 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)
