Immediately after start, check that the pressure gauge is showing a positive pressure reading
indicating that the pump is generating positive flow. Pressure deflection may only be slightly
positive at the commencement of operation until pump primes. Priming should occur within a ½
minute of starting the pumps
–
DO NOT RUN PUMPS DRY FOR ANY MORE THAN 30 SECONDS
–
Pump damage could result if pumps run dry.
•
Check that pressure has built to about 6 Bar operating pressure. Pressure could build to over
100psi (6 Bar) momentarily after start-up but should not exceed 130psi and should show a
steady reduction as the system settles down and warms up.
•
Slightly higher than normal set pressures may be experienced with cold gear oils and these
pressures will drop as the oil warms up and becomes less viscous.
•
System should settle down to a steady operating pressure at around 100 psi and pressure
should not be seen to be fluctuating. If pressure is not stable, cavitation or pump starvation
could be occurring.
•
Heavy oils (gear oils and above) can cause the pump relief valve to hammer, resulting in a
louder than normal pump noise. This noise will reduce as the oil heats and becomes more
pumpable.

Check that pressure is positive immediately after
start and rises quickly to operating pressure, not to
be greater than 6.3 bar or 100 psi
