Example of drain plugs
1. After draining the pump during long shutdown periods under
freezing conditions, blow out all liquid in passages and air
pockets using compressed air. You can prevent freezing of
pumped liquid by filling the pump with antifreeze solution.
2. Rotate the shaft by hand monthly to coat the bearings with
lubricant and delay oxidation and corrosion.
3. Where applicable, follow the motor manufacturer's storage
recommendations.
