Possible faults

FAULT
INSUFFICIENT FLOW
- Insufficient suction pipe diameter.
- Suction valve partially open.
- Air intake on the suction.
- Very viscous liquids.
- Wrong turning direction.
- Blocked filter.
- Incorrect installation of the suction pipe
with
countergradients that cause the formation
of air pockets.
- Working pressure higher than the
maximum, which causes the safety valve to
open.
INSUFFICIENT OR UNSTABLE PRESSURE
- Suction valve partially closed.
- Air intake on the suction.
- Wrong turning direction.
- Countergradients on the suction that
cause the formation of air pockets.
LEAKS THROUGH THE MECHANICAL SEAL OR LIPSEALS
- Impurities in the pumped liquid.
- Damaged friction faces due to working
dry, damaged lipseals.
BLOCKING OF THE TURNING PARTS
- Suction of foreign bodies.
ABNORMAL WORKING OF THE MOTOR
- Incorrect electric supply.
- Incorrect motor connection.
- Partial blocking in some part of the pump.
THE PUMP ABSORBS EXCESSIVE POWER
- Very high density or viscosity of the liquid.
- The pump works outside the maximum
pressure curve.
LEAK THROUGH PUMP & MOTOR OPENING
- Damaged mechanical seal or lipseal.
EXCESSIVE WORKING TEMPERATURE
- Incorrect ventilation of the equipment.
- Very high pumping temperature.
SYSTEMATIC FAULTS OF THE MECHANICAL SEAL OR LIPSEALS
- Abrasive particles in the fluid.
