1.Drain the pump casing completely of water to prevent damage from freezing
2.If complete draining is not possible, pour a small amount of anti-freeze into the casing and rotate the pump shaft to ensure mixing
3.Seal suction and discharge ports to prevent the entry of debris or other foreign material
4.If the pump has an oil lubricated seal, drain the oil from the seal cavity and refill with 30-weight non-detergent motor oil
5.For water cooled seals, place one-half pint of lubricating oil (new or used) through the discharge opening in the pump and turn engine over several times. This will prevent excessive corrosion and also will keep the mechanical seal lubricated
