(1) Poor seal. After a period of use, sealing parts of the motor manufactured by high wear-resisting materials will be aged and worn and water leakage will be happened due to poor seal.
(2) Cannot pump water. Due to the damage of bearing, deep well submersible pump cannot pump the water.
(3) Stuck pump. The phenomenon that the impeller of deep well submersible pump is blocked by debris and deep well submersible pump cannot rotate while can hear the noise is called stuck pump.
(4) Electric leakage. There is automatic trip phenomenon when leakage protector in voltage transformer room closes switch blade.
(5) Outlet pipe is damaged and leaked. If rotation of the ammeter is normal and normal sound of pump wheel of submersible pump in deep well can be heard, while deep well submersible pump pumps little water or cannot pump water, it is often caused by the damage of outlet pipe of deep well submersible pump.
Manufacturers recommend: Shenlong stainless steel deep well pump
