PRD - API 610 / BB2 between bearing pump

API 610 / BB2 Single stage radially split pump suitable for heavy duty construction; clear, toxic, corrosive, flammable and hot liquids

Design

Radially Split, single‐stage, double suction pump compliant with the latest API 610 (BB2) standards

- Radial casing split
- The double-suction impeller reduces axial thrust problems while maintaining low NPSHr.
- Removable wear rings
- Heavy duty double bearing frame to ensure optimal rigidity of the pump + fins on bearing housing for efficient cooling.
- Accessible Seal chamber per API682 and ISO21049.
- Optional cooling or heating jacket of the seal chamber.
- Shaft seal by cartridge mechanical seal + API flushing / quench plans.
- Shaft offering strong resistance to deflection.
- Standard bearing protection by labyrinth type seal and deflector.
- Centerline mounted pump casing and base plate complying with ISO13709/API610 standards.
- High radial load roller bearing.
- Back-to-Back angular contact bearings handle high axial loads.
- Casing and impeller wear rings are shrunk fitted.
- Fan-cooled bearing frame in option.
- Oil lubrication with constant level oilers.
- Discharge size from 150 mm to 400 mm.
- Flanges per ANSI B16.5 - #300 - Other flange standards upon request.
