CP horizontal radially split multistage barrel pump

Expertly designed pumps for oil and refineries

CP ISO 13709 / API 610 Type BB5 radially split barrel casing pumps are used in both high-pressure oil production and high-temperature refinery applications. There are hundreds of installations of these highly reliable pumps throughout the world.

 

Main benefits
  • Opposed impellers balance axial thrust, with no lube system needed on smaller pumps
  • Axially split inner case means rotor balance is not disturbed when installed in the pump
  • Dual volute inner case balances radial loads for longer service life
  • Twist lock barrel closure reduces maintenance time on lower temperature services
  • Cartridge design on larger pumps can speed up pump repair time
Main applications
  • Hydrotreater charge
  • Water injection
  • Ethylene shipping
  • Hydrocracker charge
  • High-pressure safety injection
Main design features
  • Double suction first-stage impeller available for low NPSHa conditions
  • Opposed impeller construction for reduced axial thrust
  • Axially split volute style inner case allows optimization of performance
  • Variety of barrel closure methods: twistlock, bolted, bolted with SuperBolts™

Applications

Boiler feed water and booster pumps

Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of FWP is their high differential head.

Crude oil pipeline mountainous terrain

In remote areas, there may not be power available, or, terrain may be so steep that all the pressure rise has to be made in 1 station. Each pump must make the entire head. Pumps are often run in parallel. Hundreds of Sulzer multistage pump performances meet such high pressure requirements.


Crude oil pipeline offshore to onshore

All the pressure rise must be made in the crude shipping pumps on the platform. Salt spray is corrosive and platform movement during storms can affect reliability. Specially packaged Sulzer multistage pumps are used to move crude oil from offshore platforms to onshore storage or pipeline systems.

Flow assurance (dead oil / hot oil)

Pumps for flow assurance service, also known as dead oil and hot oil circulation, are critical to maintain oil production in deep cold water. Though usually driven by an electric motor, the Sulzer BB3 and BB5 pumps can be engineered with diesel engine drivers. Along with our reputation for quality and efficiency, our pumps are right for this service.

Hydraulic power recovery turbine

Many industries aim to reduce their ecological footprint by minimizing energy consumption. Sulzer Hydraulic Power Recovery Reaction Turbines can be used to capture lost energy.

Liquefied petroleum gas pipelines

Liquefied Petroleum Gas (LPG) mixtures (ethane, propane, butane) can have vapor pressure up to 40 Bar, specific gravity less than 0.40, and almost no lubricity. Sulzer provides special materials, acoustic studies, and lateral analysis to assure reliable performance with varying flow, speed, and fluid conditions.

Refined product pipelines

Thousands of Sulzer multistage pipeline pumps move diesel fuel, jet fuel, gasoline, and other refined products all over the globe. Sulzer’s global service centers, service and retrofit not only our own pumps, but other pumps and motors as well.

Seawater treatment

With enhanced oil recovery methods, often prior to injection sea water needs to be treated to remove or reduce salt content. Sulzer’s pumps achieve this by delivering sea water to the SRU / SWRO membrane racks.

Supercritical and compressible fluid pipelines

For the past 30 years, Sulzer multistage pumps have been used to pump compressible, dense phase ethylene and CO2 at normal and supercritical pressures. Compressible performance prediction, acoustic studies, and, lateral analysis, are all part of service provided by Sulzer engineers for such rigorous applications.
