Noise from pump, but only at low pressure
Action:
Adjust speed from maximum to minimum (see “Speed adjustment for Actuator on LPU (v.2)” on
page 83). If possible, place key on emergency operation shaft of the actuator and hold against rotat-
ing direction (i.e. operating pressure must be approximate 30 bar) (only possible for BRC 125, 250,
500).
Warning!
Beware of huge force, actuator cannot be stopped by hand!
Then if:
•
Sound disappears
Too low compression of O-ring on motor shaft, so that rotor is vibrating on coupling.
Replace O-ring.
•
Sound is unchanged
A pump piston is operating too tightly and does not follow the ball bearing curve during move-
ment. At relatively high pressure it is pressed out hydraulically. The sound can disappear at start-
ing-up. Otherwise pump is dismounted and pistons and rotor are checked for coverings or burrs.
Note!
If pump rotor has to be replaced the stator version has to be checked (check placement
and number of expanding plugs). If stator versions are different both rotor and stator must
be exchanged (complete pump set, see “Replace Pump in LPU” on page 93).
