Pneumatic Diaphragm Pump
QBK Pneumatic Diaphragm Pumps also called Air Operated Double Diaphragm Pumps (AODD Pump) are rugged and durable compact pumps, can handle any products that pours, form clean water to highly viscous, abrasive and chemically materials.
Simple structure, easy to use and maintenance, less wearing parts. It can be working under liquid and running dry as well.
Suction up to 5m, max discharge pressure is 7bar, max grain diameter is 10mm, max liquid viscosity is 10,000C.S.t.Material: PP, Aluminum, Cast Iron, Stainless Steel. Diaphragm material: NBR, Viton, Teflon, FEP etc. Flow rate can be controlled from zero to max flow by increasing or decreasing air pressure.
