TROUBLESHOOTING

Some of the following may help pinpoint the problem:

Pump does not pump:

Lost its prime from air lead or low level in tank.

Suction lift too high.

Rotating in wrong direction.

Strainer clogged.

Bypass valve open, pressure relief valve set too low or pressure relief valve poppet stuck open.

Improper end clearance.

Pump worn out.

Any changes in liquid, system or operation that would influence pump or coupling performance, e.g. new liquid, additional lines or process changes.

Temperature changes either in the liquid or the environment.

Magnetic coupling is decoupling. Change in application (temperature, pressure, viscosity,’ etc.) may require torque beyond coupling capabilities.

Pump starts, then loses its prime:

Supply tank empty.

Liquid vaporizing in the suction line.

Air leak or air pocket in the suction line.

Pump is noisy:

Pump is being starved (heavy liquid cannot get to pump fast enough). Increase suction pipe size, reduce length or slow down pump.

Pump is cavitating (liquid vaporizing in suction line). Increase suction pipe size or reduce length.

Check alignment.

Magnetic coupling decoupled. Shut off and restart.

Pump not delivering up to capacity:

Starving or cavitating - increase suction pipe size or reduce length.

Strainer partially clogged.

Air leak somewhere in suction line.

Running too slow. Is motor the correct speed and wired up correctly.

Pressure relief valve set too low, tuck open or has damaged poppet / seat.

Bypass line around pump partially open.

Pump worn out or too many gaskets.

Pump takes too much power (stalls motor):

Liquid more viscous than unit sized to handle.

System pressure relief valve set too high.

Coupling misaligned.

Bushings frozen up or liquid set up in coupling.
