How to buy the right lobe lobe pump

The lobe pump should be selected from the following aspects:
1. Its own parameters
It is necessary to determine its own parameters, such as what is the maximum sewage flow during the peak period. This can be decided according to the number of drainage outlets, which can be calculated by professional technicians.
2. Head
It is also necessary to consider the head, insufficient head will lead to the ground medium can not be excluded normally, and even the phenomenon of media backflow; and too high head will lead to the waste of subsequent resources, generally speaking the appropriate head is the vertical height of the bottom of the medium to the water pipe network, if you are not sure of the head you need, you can be measured by professionals on site.
3. The type of sewage medium
It is also necessary to know the type of medium in order to choose the pump with which kind of inlet and rotor, if the sewage contains granules, then the abrasive type of sewage lifting pump should be chosen. If the sewage contains fibers, then you should choose the cutting type of sewage lift pump pump. Of course, if it is a source of sewage that hardly produces impurities such as washing machines and hand washing trays. It is recommended that you can choose the sewage pump with ordinary rotor, which is more conducive to cost saving.
4. Heat dissipation
When the lobe lobe pump is running, the speed is high and the heat will be high, and the ability to dissipate heat becomes an important indicator to measure it. Look at the material of the motor and the material of the motor casing, look at the lobe lobe pump is outside the tank generally do the pump is better. The pumps inside the tank are generally not too technically advanced heat dissipation will also be much worse.
5. Box material
Generally the box material of dirty cam lobe pump is PP∕PE∕ABS, ABS has the highest corrosion resistance, HDPE material is more suitable for large box sewage lifting pump. But try not to choose stainless steel welded box, because the vibration of the pump will lead to cracking, leaking water at any time, and very difficult to maintain later. globe pump6. Service life
This one is definitely the longer the better, because replacement maintenance is more troublesome. Many people start to buy some inexpensive pumps to save cost, and finally several years down the road the maintenance and replacement cost has exceeded the cost of purchasing a safer and more stable cam lobe pump product at that time.
7. Maintenance difficulty
Mainly depends on the pump your installation location, generally the cam lobe pump outside the sewage lift pump box is the easiest to maintain. The price of the external pump equipment is of course much higher than the built-in one, because the performance of the external pump is excellent and the whole manufacturing cost is higher. Also look at whether the equipment with backwash function, if not backwash function is recommended to choose carefully, otherwise the later cleaning very own.
