2. Calculate the required head of the macerator pump. Sometimes customers calculate the flat conveying distance into the head, which is wrong. The head can be calculated only after the flat conveying distance is multiplied by the friction coefficient.
3. The wear of pipeline elbow and pipeline friction shall be included. These are different in the actual situation, and it is quite troublesome to calculate accurately. Therefore, it is recommended to leave some space to ensure that the water pump can pump water.
4. If stainless steel sewage pump is selected, it is also necessary to find out the pH of water quality, including particle diameter, and select appropriate stainless steel material. Generally, 304 material is suitable for pH4 ~ 10. Beyond this range, 316 or 316L stainless steel is recommended.
5. The macerator pump must be used within the rated head range to ensure that the motor is not overloaded.
For example, the actual required lift is 30m, but pumping with a pump with a standard lift lower than 30m is a wrong use method, which will cause motor overload and burn out in serious cases.
6. The macerator pump pipeline must be dredged. If the pipeline is blocked, it will also cause motor overload and burn out the motor in serious cases.
