ZW self-priming non-clogging sewage pump failure reasons and maintenance methods

Self-priming sewage pump failure phenomenon
Cause Analysis of Self - priming Sewage Pump Faults
Self-priming sewage pump troubleshooting
Self-suction sewage pump no water
Pump body without stock solution or lack of stock solution
Add enough
Suction pipe leakage
Eliminate pipeline leakage
The voltage is too low
Adjust the voltage
Suction stroke or suction line is too long
Reduce suction or shorten the pipeline
Mechanical seal leaks too much
Repair or replace
Self-suction sewage pump lack of water
Due to improper use, impeller runner or suction line is blocked
Eliminate clogs
Impeller wear serious
Replace the impeller
Insufficient power The speed is too low
Adjust to rated speed
Self-priming sewage pump noise, vibration is too large
Feet unstable
Reinforced
Bearing wear serious
Replace the bearing
Pump and motor spindle is not coaxial
Adjust concentricity
Self-suction sewage pump bearing temperature is too high
Grease deterioration or dry
Change the grease
Bearing damaged
replace
Self-suction drain pump leaks
Loose coupling bolts
Tighten
Seals wear
replace
