PUMPS TESTS

Performance Tests (5 points) Standard used: API 676.

  • Atmospheric pressure
  • Intermediate
  • Differential pressure
  • Intermediate
  • Pump discharge

Tests runs:

  • At rated speed
  • Flow rate
  • Total head= f(Q)
  • Speed of rotation
  • Efficiency = f (Q) 
  • Power drawn at shaft end = f (Q)

NPSH Tests = f (Q)

Test is realized by sucking up the air with a vacumm pump in the water tank. This
operation enables to decrease the pressure at the suction of the pump until
obtaining the first sign of cavitation. The measurement is done when the total
head pressure of the pump decreased of 3%
