How to use the self-priming pump？

Self-priming pump use

The preparation before starting has inspection work

1.This series of self-priming pumps are lubricated with high-quality calcium-based butter and No. 10 oil according to the working condition of the pump. If the pump is lubricated with grease, the grease should be regularly added to the bearing housing, and the oil-lubricated pump should be used. If the oil level is insufficient, add it.

2. Check whether the liquid in the pump casing is higher than the upper edge of the impeller. If it is insufficient, the liquid can be directly injected into the pump body from the filling port on the pump casing, and should not be started in the case of insufficient liquid storage. Otherwise, it will not work properly and it will damage the mechanical seal.

3. Check if the rotating parts of the pump have a card position collision phenomenon.

4. Check the nut of the pump body and the nuts at the joints for looseness.

5. Check the coaxiality and parallelism between the pump shaft and the motor shaft.

6, check the inlet pipe for leaks, if there is a leak, you must try to eliminate.

7. Open the valve of the suction line and slightly open (not fully open) the outlet control valve.
