XRotor WaterPump (Troubleshooting No Water Output)

Diaphragm pumps do not transport water

The diaphragm pump has two diaphragms, which need to be lubricated with water or oil during storage. Long-term non-lubrication, or the delivery of highly viscous liquid, will cause the diaphragm to stick to the pump body, which can not bounce back normally, resulting in the pump being unable to transport water. The red part in the image below.

1. How to prevent the diaphragm from sticking.

A.  After the end of use, use the pump to transport a certain amount of water (>2L), discharge the pesticide or other liquid residues in the pump, and clean the inside of the pump. And keep this water in the pump, do not do any drying, easy to lubricate the diaphragm.

B.  When storing the pump for a long time, reserve water inside the pump to keep the water lubricating the diaphragm. Do not worry that low temperature will damage the diaphragm, the diaphragm of the pump is an elastic plastic, it has good elasticity, and will not freeze.

2. How to get a pump to transmit water.

A.  Use force to separate the diaphragm from the pump body. Use a high-pressure air gun or point your mouth (not recommended) at the outlet and blow vigorously. Separate the sticky ones, and they can be used normally.

B.  Lubricate the diaphragm again with clean water. Water is poured into the water outlet from the pump, about 5-10ml of water, wait for about 2 minutes, and the diaphragm can be lubricated again. The pump can be used again.

C.  Two pumps are used in series, and the pump that can work normally drives the pump that cannot work normally. After testing, the two pumps work in series, and after the series, the pressure is doubled, and the sticky diaphragm can be easily blown open.
