Design and operation principle of stand unit for testing stages of electric-centrifugal pumps (ECPs) are described.
Methodological framework for conducting accelerated life testing of ECPs is set out, which make it possible to fulfill
qualitative assessment of the service life of stages of submersible electric-centrifugal pumps of various designs.
Examination of experimental and pre-production ECPs stages samples operation at the laboratory stand at artificially
created and severe conditions of the submersible pump exploitation provides identification and timely elimination of
technological and structural defects of items on test. At that, material and time expenditures for the laboratory research
are significantly lower than for the implementation of field tests. The use of verified and high-precision measuring
instrumentation in the process of ECPs testing makes it possible to determine hydraulic and energy characteristics of
existing and experimental stages of centrifugal pumps stages in real-time mode.

Key words: electric-centrifugal pump; oil production; stand unit; accelerated life testing; reliability.
