①The sanitary pump that has not been installed should be coated with a suitable anti-rust agent on the unpainted surface. Bearings lubricated with oil should be filled with appropriate oil, and bearings lubricated with grease should be filled with only one type of grease. Do not use mixed grease.
②Pump clean liquid for a short time, flush, suction pipeline, discharge pipeline, pump casing and impeller, and drain the flushing liquid in pump casing, suction pipeline and discharge pipeline side by side.
③Drain the oil in the bearing box, add clean oil, thoroughly clean the grease and then fill with new grease.
④ Seal the suction port and discharge port, store the pump in a clean, dry place, protect the motor windings from moisture, and spray the inside of the pump casing with anti-rust and anti-corrosion liquid.
⑤The pump shaft rotates once a month to avoid freezing, and lubricate the bearings.
