Our diaphragm pumps are positive displacement pumps that use a reciprocating action of a membrane and a non-return check valve to pump a fluid. A very economical diaphragm pump is our 54908-037 which is oil-less with a single phase, ball bearing type motor with internal thermal protection. It comes complete with muffler, vacuum gauges, hose nipples, rubber feet and carrying handle. It is manufactured by Gast, a leader in manufacture of high quality diaphragm pumps. Much like the peristaltic pumps manufactured by Welch, these diaphragm pumps are used in research and development, pharmaceutical and general laboratory work.
About Diaphragm & Peristaltic Pumps
Diaphragm pumps and peristaltic pumps are extensively used throughout the laboratory in sampling, moving liquids, gases, or mixed-phase media. While the Welch peristaltic pumps such as our 84009-696 has the capacity to move liquids, gases or solids and is ideal for laboratory research due to its reversible motor and flow control button, diaphragm pumps are single phase pumps that utilize a membrane and a non-return check valve. Whether your needs call for diaphragm pumps or peristaltic pumps, dependability and service are key ingredients that you will find from New Star Environmentals.
