Preparation and inspection work before starting the self priming pump

1. This series of self priming pumps uses high-quality calcium based grease and No. 10 engine oil for lubrication according to the operating conditions of the pump. If using butter lubrication, the pump should regularly fill the bearing box with butter. If using oil lubrication, the pump should fill it up if the oil level is insufficient.
2. Check whether the liquid storage inside the pump casing is higher than the upper edge of the impeller. If it is insufficient, the liquid storage can be directly injected into the pump body from the liquid filling port on the pump casing. It should not be started and operated when the liquid storage is insufficient, otherwise it cannot work normally and may damage the mechanical seal.
3. Check whether the rotating parts of the pump are stuck or bumped.
4. Check if the nuts at the pump body feet and various connections are loose.
5. Check the coaxiality and parallelism between the pump shaft and the motor spindle.
6. Check if there is any air leakage in the inlet pipeline. If there is any air leakage, it must be eliminated.
7. Open the valve of the suction pipeline and slightly (not fully) open the outlet control valve.
