We offer most of the main Lincoln® diaphragm pumps out there today. With these diaphragm pumps you can pump abrasive materials through their low interval velocities without damaging the pump itself. The pumping is also gentile enough not to break fragile materials that may need to be pumped. Because these pumps do not require motors, seals, or packing that can leak they are environmentally friendly. Air-operated pumps are also able to dry prime under most flooded suction or suction lift conditions. Once pumping is finished pumps can run dry without damage. The inlet air supply is adjustable making it possible to change the flow based on immediate suction needs.
