Is the filter installed in front of the pump or at the back of the water?
This problem will be used to ask, you installed in the pump before the pump even with protection, if installed on the pump after the sand will flow to the pump, so that the long-term pump will wear, wear no force pump.
Because the water will behind the equipment, but the pressure filtration pump (if the level and anti infiltration treatment system, almost certainly in need of reverse osmosis booster) should be used as diaphragm pumps, so as to avoid re pollution of water sources.Self cleaning filter inlet pressure requirements higher, otherwise it is difficult to achieve cleaning effect, if the water pressure is not guaranteed, certainly need to boost water intake,
The installation of pump is filter, filter according to the work requirements, because the water pressure and filter water supply association, if not through the water pressure filter to meet the requirements should be considered in the water before pressurization, installing pumps, the pump can use general centrifugal booster pump
