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 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™
