What Are The Disassembly Steps For The Impeller Of The Desulfurization Pump

Sep 12, 2025

The desulfurization pump is a common equipment in industrial production, mainly used to treat industrial wastewater containing sulfides. During the use of the desulfurization pump, due to various reasons, it may be necessary to disassemble the impeller. The following will provide a detailed explanation of the disassembly steps for the impeller of the desulfurization pump.
The desulfurization pump is mainly composed of pump body, impeller, shaft seal and other parts. Among them, the impeller is the core component of the desulfurization pump, responsible for transporting liquid from the pump's suction port to the discharge port. Therefore, the disassembly of the impeller is an important part of the maintenance of the desulfurization pump. The steps for disassembling the impeller are as follows:

1. Turn off power: Before carrying out any maintenance work, it is necessary to turn off the power first to ensure safe operation.
2. Dismantling the pump body: Use appropriate tools such as wrenches or screwdrivers to remove the fixing bolts and nuts of the pump body, and then remove the pump body from the base.
3. Dismantling the shaft seal: The shaft seal is an important component to prevent liquid leakage from both ends of the pump. Use a wrench or screwdriver to remove the fixing bolts and nuts of the shaft seal, and then remove the shaft seal from the pump shaft.
4. Dismantling the impeller: Before disassembling the impeller, it is necessary to first remove the blades on the impeller. Use a wrench or screwdriver to remove the fixing bolts and nuts of the blade, and then remove the blade from the impeller. Then, use a wrench or screwdriver to remove the fixing bolts and nuts of the impeller, and finally remove the impeller from the pump shaft.

5. Cleaning and inspection: The disassembled impeller needs to be cleaned and inspected. The purpose of cleaning is to remove dirt and impurities from the impeller, and the purpose of inspection is to determine if the impeller is damaged or worn. If the impeller is damaged or worn, it needs to be repaired or replaced.
6. Installation: After completing cleaning and inspection, the impeller can be installed. Firstly, install the blades onto the impeller, and then use a wrench or screwdriver to tighten the fixing bolts and nuts of the blades. Then, install the shaft seal onto the pump shaft and use a wrench or screwdriver to tighten the fixing bolts and nuts of the shaft seal. Finally, install the pump body onto the base and use a wrench or screwdriver to tighten the fixing bolts and nuts of the pump body.
The above are the disassembly steps for the impeller of the desulfurization pump. It should be noted that the disassembly and installation of desulfurization pumps require professional technicians to prevent equipment damage or personal injury caused by improper operation. At the same time, the disassembled components need to be cleaned and inspected to ensure the normal operation of the equipment.
