Lifeng - Dosing Pumps
Model Selection : Dosing pumps are used to deliver polymeric coagulant or inorganic flocculants to the flocculating tank. Due to the high viscosity of polymer coagulants, we should choose high viscosity resistance dosing pumps. Flow = DS Capacity per hour of configured dewatering machine ÷ Flocculants addition rate ÷ Dilution ratio.
Mechanical Diaphragm Pump
Description: The diaphragm pump has two sections separated by a diaphragm. In one section a piston or plunger operates in a cylinder in which a non-corrosive fluid is displaced. The movement of the fluid is transmitted by means of flexible
diaphragm to the liquid to be pumped. The only moving parts of the pump that are in contact with the liquid are the valves, and these can be specially designed to handle the material. In some cases, the movement of the diaphragm is produced by direct mechanical action, or the diaphragm may be air actuated.
