Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.

Troubleshooting Chart

PROBLEM

PROBABLE CAUSE

CHECK

- Threaded joints in the suction tightness.
- Gaskets for no wear.
- The mechanical seal for leaks.
- The drain plug has leaks.
- The vacuum gauge may be leaking.

2. Insufficient liquid in the 
pump casing.

- That the pump's body is filled with water.

3. Low operating speed.

- The motor speed (RPM).

- Impeller rotates freely.

- Internal parts are clean.

5. Mechanical defect.

- That the internal parts are not worn.

B) The pump does not prime, 
the vacuum gauge reading 
indicates higher than normal.

1. Pipe clogged suction.

- The suction line is clean.

1. The pump speed is very 
low.

- The voltage is correct.

2. Mechanical defects.

- The internal parts for wear.

- The discharge is clear of obstructions.

- That the discharge valves operate correctly.

1. suction dynamic level 
too high.

- When the pump is operating, never lacks 
water in the suction.
- For leaks in suction piping, flanges and 
gaskets.
- That there is no vortex effect at the end of 
the suction, this lack of water.
- That screws are tight at the base.
- 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
- If reducing flow makes the noise gone, then 
the problem is in the point above; partially 
close the discharge valve.
- The bearings for wear.
- That there is oil in the deposit.
- The impeller does not have any foreign 
material.
- The pump is operating in the range.
- That the alignment is correct.

1. Low voltage.

- The voltage is correct.
- The amperage of the plate is not exceeded.
- There is no foreign material that may force 
the impeller.
- That the motor is suitable for the pump.

2. Overload.

A) The pump does not prime, 
the vacuum gauge indicates a 
lower reading than normal.

F) The pump priming pumps 
well and satisfactorily but noisy.

E) The pump loses its priming 
during operation, vacuum 
gauge reading drops to zero.

G) Motor overload.

4. Vibration.

1. Pump base is loose.

2. Cavitation.

3. Bearings.

2. The pump is sucking air.

D) The pump priming good 
vacuum gauge reading is 
almost normal, reading the 
manometer is greater.

1. Discharge obstructed.

1. Air leak in the suction 
system.

4. Bound pump.

C) The pump priming good 
vacuum gauge reading is 
normal, the manometer 
indicates a lower pressure than 
normal.
