QBY Series Pneumatic Diaphragm Pump not only can exhaust the flow liquid, but also can convey some uneasy flow media, with the merits of self-pumping pump, diving pump, shield pump, slurry pump and impurity pump etc.
There are four kinds of material: cast iron, aluminum, engineering plastic, and stainless steel. The diaphragm pumps according to different liquid medium, butyl rubber were used respectively to either a Buna-N rubber, Neoprene rubber, F4 fluorine rubber, F46 fluorine rubber and so on, to meet the needs of different users.
