adhesive pump / pneumatic / self-priming / double-diaphragm
for viscous fluids, for solids-laden fluids, discharge
The Air-Operated Diaphragm Pump is able to pump out viscous materials, as well as abrasive and sheer-sensitive targets. It has no motors, seals, or packing which have the risk of leaking, thus making it environmentally friendly.
The pump features a self-priming feature which enables it to dry prime under flooded suction conditions. A variable flow property enables the regulation of the inlet air supply to adjust the flow. Deadheads installed in the pump prevent closed discharge, while an excessive back pressure stops the operation without damage.
