Advances in diaphragm design have extended pump versatility, led to smaller and lighter pumps, and boosted capability in pump flow, vacuum, and reliability.

Whether used to transfer, dispense, or otherwise handle gases or liquids, mechanically driven diaphragm pumps offer benefits associated with their relatively simple construction, oil-free operation without maintenance, and uncontaminated delivery of the pumped medium. Advances in diaphragm design have extended their potential and versatility for industry and research applications, helped contribute to the development of smaller and lighter pumps to accommodate ever-shrinking envelopes, and boosted overall capabilities in pump flow, vacuum, and reliability.
