How to select the type of pneumatic diaphragm pump
First of all, the plate filter press is driven by the flow of the pump. The flow is one of the important data for selecting the pump. The selection of the pump should be based on the processing capacity and processing period of the equipment. Secondly, according to the volume of the filter chamber of the plate and frame filter press, the moisture content of the sludge after dewatering, and the sludge concentration before entering the plate and frame, the amount of sludge required for each dewatering operation of the plate and frame is converted. Then, determine a reasonable mud feeding time, such as 2-3 hours. Calculate the flow rate.
Third, pneumatic diaphragm pump material: if it is common biological sludge, ordinary cast iron or aluminum alloy material is selected, which is more economical. Other special sludge, according to the specific sludge composition, choose pneumatic diaphragm pump material, such as engineering plastic, stainless steel 304 or 316L, fully lined fluoroplastic diaphragm pump.
