Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
PROBLEM
A) The pump does not prime,
the vacuum gauge indicates a
lower reading than normal.
B) The pump does not prime,
the vacuum gauge reading
indicates higher than normal.
C) The pump priming good
vacuum gauge reading is
normal, the manometer
indicates a lower pressure than
normal.
D) The pump priming good
vacuum gauge reading is
almost normal, reading the
manometer is greater.
E) The pump loses its priming
during operation, vacuum
gauge reading drops to zero.
F) The pump priming pumps
well and satisfactorily but noisy.
G) Motor overload.

2. The pump is sucking air.
- That there is no vortex e ect at the end of
the suction, this lack of water.
- That screws are tight at the base.
1. Pump base is loose.
- There are no cracks in the base.
- The dynamic level is not too high
- That the pumping capacity is not too much.
- The pump is operating in the range of NPSHR
2. Cavitation.
- If r
the problem is in the point above; partially
close the discharge valve.
- The bearings for wear.
3. Bearings.
- That there is oil in the deposit.
- The impeller does not have any foreign
material.
4. Vibration.
- The pump is operating in the range.
- That the alignment is correct.
