When the submersible pump operates normally for about 2000 hours, the mechanical seal must be replaced, and new lubricating oil must be replaced at the same time.
After repairing or replacing the integral sealing box, the air pressure test should be carried out. For the specific requirements of the air pressure test, please contact our company - Tuohai Pump Industry Co., Ltd.
When replacing the whole seal, it needs to be disassembled in sequence. When assembling, it can be done in the order of disassembly. During assembly, it should be kept clean.
When the submersible pump is not in use, it should not be immersed in water for a long time to avoid dampness inside the pump. The submersible pump should be lifted and placed in a dry and ventilated room.
The cable leads must be checked frequently for cracks to prevent leakage and electric shock. The cable lead should not be too thin or too long, the joint must be firm, and ensure good insulation.
After one year of use, the submersible pump should be repainted and de-rusted according to the corrosion condition of the surface.
Impellers, seals, bearings, bushings, and other vulnerable parts of the submersible pump, as well as "O" rings, rubber gaskets on the oil screw holes, etc. can be purchased together when ordering the pump, or you can also buy accessories with the same parameters locally.
