Pump Common Failures and Maintenance
| Problem | Reason Analyze | Maintenace |
| Pump fails to run | 1、thermal fuse burned
2、pump jammed or rusted 3、capacitor damaged 4、Low voltage 5、pump is working in interruption (Thermal protector working） 6、pump burned |
1、Change the thermal fuse
2、clear the eyewinker and rust 3、change capacitor 4、Use voltage stabilizer,enlarge cable wire diameter and shorten the cable length to decrease cable pressure and loss 5、Check whether pump voltage too high or too low or pump overloaded working。Find the problem then solve 6、Repair the pump |
| Pump cannot pump out water | 1、No enough water in the water filling hole
2、too high suction 3、water absorption tube connection leak gas 4、Lack water source，bottom valve on the water 5、Mechnical seal leak water 6、Pump head、pump body broken |
1、Add full water in the water filling hole
2、remove pump to reduce the pump suction 3、use teflon tape or sealant to tighten the inlet connection again 4、make the bottom valve surbmerse in the water 5、change or repair the mechanical seal 6、change pump head or pump body |
| Small flow,low lift | 1、impeller and pump head wear
2、Mechnical seal leak water 3、Impeller blocked by sundries 4、filter blocked 5、Low voltage |
1、change the impeller ,pump head
2、change or repair the mechanical seal 3、clear the impeller sundries 4、clear the sundries on the filter 5、Enlarge voltage |
