What matters should be noted when choosing a lobe lobe pump

The following 7 points need to be noted when selecting a lobe lobe pump:
1. Its own parameters
It needs to determine its own parameters, such as what is the maximum sewage flow rate during the peak period. This can be decided according to the number of drainage ports, 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 the head is too high 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 choose the abrasive type of sewage lifting pump. 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 choose the ordinary rotor sewage pump can be, which is more conducive to cost savings.
4. Heat dissipation
When the lobe lobe pump is running, the speed is very high and the heat will be high, and the heat dissipation ability becomes an important indicator to measure it. Look at the material of the motor and the material of the motor housing, look at the lobe lobe pump is outside the water 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 of 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, the later maintenance is very difficult.
6. Service life
This one is definitely the longer the better, because the replacement maintenance is more troublesome. A lot of start to save costs to buy some inexpensive pump, and finally a few years down the maintenance and replacement costs have exceeded the cost of the product at the time to buy a more secure and stable cam lobe pump.
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. Because the maintenance does not need to open the box at all, of course, the price of the external pump equipment is much higher than the built-in, because the performance of the external pump can be excellent, the whole machine manufacturing costs are also 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.
