FIELD: engines and pumps.
SUBSTANCE: proposed method consists in creating test pressure at pump outlet with pump shaft immobile and measuring test fluid flow rate at pump inlet. In measuring inner leaks, pump inlet is additionally communicated with drain chamber. Thereafter, total flows rate of test fluid is measured.
EFFECT: lower power consumption in tests, metal input and possibility to test rotary piston pumps.
