What is the maintenance and upkeep of CDL stainless steel vertical centrifugal pump? Today, the editor of Dengfeng Pump Industry 

will talk to you:

1. The inlet pipeline must be highly sealed and cannot leak water or air;

2. Prohibition of long-term operation of multi-stage centrifugal pumps under cavitation conditions;

3. Prohibit the long-term operation of multi-stage centrifugal pumps under high flow conditions with motor overcurrent;

4. Regularly check the motor current value during the operation of the multi-stage centrifugal pump, and try to make the pump 

operate within the design operating range as much as possible;

5. Multi stage centrifugal pumps should be supervised by dedicated personnel during operation to prevent accidents;

6. The bearings of the multi-stage centrifugal pump should be lubricated every 500 hours of operation;

7. After long-term operation of the multi-stage centrifugal pump, due to mechanical wear, the noise and vibration of the unit increase.

It should be stopped for inspection. If necessary, vulnerable parts and bearings can be replaced, and the unit should be overhauled

Maintenance and upkeep of mechanical seals

1. Mechanical seal lubricant should be clean and free of solid particles;

2. Strictly prohibit mechanical seals from working under dry grinding conditions;

3. Before starting, the pump (motor) should be turned a few times to prevent sudden starting from causing mechanical seal breakage

 and damage.
