Subsea Booster Pumps


Framo Subsea Booster PumpsMultiphase high boost pump

FEATURES:

DUTY • Medium to High range GVF applications for unprocessed well boosting

• Low GVF applications, e.g. G/L Separation cases

TYPE • Proven helico-axial multiphase pump• Thrust balance design• Sand tolerant design

DATA • Efficient up to 60% GVFDATA Efficient up to 60% GVF• Up to 50,000 bbl/d capacity• Up to 150 bar differential pressure• Up to 2,600 kW shaft power rating

STATUS • Qualified for operation with GVF 0-100%

• Differential pressure up to 200 bar with GVF 0- 60% and 100 to 130 bar


with GVF 60–80%.• Ready for field application

High Boost – Further Testing

1. Wear Testdetermine effect of increased clearance in Balance Piston:

a. hydraulic loss due to backflow from outlet to inletb. rotor dynamic behavior of pump shaft c. effects of wear of swirl breaks

2. High Viscosity Test:a. establish hydraulic and mechanical performance at

high viscosities (250 cP/ 0- 80% GVF)b if t t f t hi h i itib. verify start- up of pump at very high viscosities

(4000 cP)
