AMDP 隔膜泵安装与维护设备

Membrane pumps or diaphragm pumps belong to the group of positive displacement pumps, where the pressure increase is obtained by pushing elastic walls, known as, membranes or diaphragms, which change the volume of the chamber. Retention valves, usually made with an elastomer material, make sure that the movement of the fluid takes place from the area of lower pressure to that of greater pressure.

Diaphragm pumps are often used as dosing pumps because they have a stroke control system. Due to the corrosion resistance of these pumps and because of the fact that they don’t need to be primed to work, this type of pumps is widely used in the industry, especially the chemical industry, to drive virtually any liquid, and in many industries involving acids, petroleum derivatives, solvents, paints, varnishes, inks, sewage sludge, reactants.
