QBY Air-operated Pneumatic diaphragm pump
Summary :
QBY and QBK series air operated diaphragm pumps not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self-pumping pump, diving pump, shield pump, slurry pump and impurity pump etc.
There are 8 product specifition: φ10mm(3/8"), φ15mm(1/2"), φ25mm(1"), φ40mm(1 1/2"), φ50mm(2"), φ65mm(2 1/2"), φ80mm(3"), φ100mm(4"). Five kinds of material: aluminum alloy, cast iron, stainless steel, engineering plastic, cast iron fluorine plastic lined. The diaphragm pump according to different liquid medium butyl rubber were used respectively to either a synthetic rubber, fluorine rubber, Teflon, PTFE lining and so on, to meet the needs of different users.
