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)
