Some users will encounter the problem of impeller cutting when selecting acid resistant submersible pump or working conditions. The impeller cutting refers to the removal of manual cutting and then installing it for use. Dismantling the impeller of the water pump: Generally, the pump body is disassembled, and then there is a top wire at the bottom of the impeller, which is fixed on the shaft. It is not easy to unscrew it. It is recommended to use a casing wrench.

The main purposes of acid resistant submersible pump for impeller cutting are:

1. Mainly to adjust the head flow parameters of the acid resistant submersible pump;

2. To adapt to the user's actual working conditions;

3. To achieve the purpose of normal use and operation.

Changes after cutting the impeller of the water pump:

1. The impeller is cut by mechanical means, generally lathe processing

2. After cutting, the diameter of the impeller becomes smaller. According to the cutting law, its head and flow will also become smaller

Acid resistant submersible pump is usually impeller cutting under what conditions?

1. Generally, when selecting acid resistant submersible pump, the actual performance parameters are between the two pump types.

2. The smaller pump type cannot reach the required head flow, and the larger acid resistant submersible pump pump type is higher than the required flow head. In this case, the impeller of the acid resistant submersible pump needs to be cut.

3. How much to cut is calculated according to the law of cutting
