PUMP SHUT DOWN
Never stop the pump while pumping solids through the system. This will plug the
piping. Lift the pump into clear fluid for as long as it takes to flush the entire system
of any slurry.
IMPORTANT
If you operate and store your pump in environments subject to below-freezing
temperatures:
1.
After the pump has been shut down, completely drain wet end, water jacket
and piping. Failure to do so will result in serious damage to your equipment.
2.
Be aware that the motor seal oil can thicken during cold storage to the point
where it will be too viscous and can not provide adequate lubrication for start-
up. Pre-heat the pump as required before start up.
3.
Be aware that certain elastomer components (lip seals, o-rings etc.) must not
be operated if their temperature is below -4°F (-20°C). Pre-heat the pump as
required before start up.
