API 610 BB3

Design Specifications:

• Horizontal, axially split multi stage pump
• Double volute, with overflow return channels
• Stiff shaft supported by internal, product lubricated sliding bearings
• Opposed side suction and discharge nozzles in bottom half of the casing
• Dismantling without breaking pipe lines
• Mechanical seal (single, double, tandem)

Applications:

• Crude oil
• Petrochemical products
• Seawater
• Feed water

Advantages:

• Control of all clearances and setting due to inner case design
• Only one external high pressure seal
• High compensation of hydraulic axial thrust
• Small axial thrust bearing
• Lower leakage loss through piston, resulting in higher efficiency
• Dynamically balanced rotating assembly
• Higher critical speed due to the supporting effect of centre stage piston
• Impeller shaft and wear parts remove as complete unit
• Easy to inspect

Exploitation:

• Pipeline pumps
• Injection pumps
