Pneumatic diaphgagm pump

Pneumatic diaphgagm pump Not only can exhaust the flow liquid but also can convey uneasy Long life and low malfunction

Pneumatic diaphgagm pump

QBK air operated diaphragm pumps is the third generation of pneumatic diaphagm pump, with the trait of long life and low malfunction.It can not only can exhaust the flow liquid,but also can convey some uneasy flowed medium,with the metrits of self-pumping pump,diving pump,shield pump,slurry pump and impurity pump etc.

1)There are 8 proudct models:

Diameter-10mm(3/8"),15mm(1/2"),25mm(1"),40mm(1 1/2"),50mm(2"),65mm(2 1/2"),80mm(3"),100mm(4").

2)Kinds of materials

Aluminum Alloy,Cast iron,Stainless steel

3)The diaphragm pump according to different liquid medium rubber were used respectively to either a synthetic rubber,fluorine rubber,Teflon,PTFE lining and so on, to meet the needs of different users.
