Industrial Diaphragm Pumps

Common Applications for Industrial Diaphragm Pumps

Diaphragm pumps, a type of positive displacement pump, are the workhorses of industrial fluid transfer because they handle conditions that destroy other pump types. Common applications include:

• Chemical transfer of acids, caustics and solvents, with PTFE or polypropylene diaphragms matched to fluid compatibility

• Wastewater and sludge handling, including produced water in oil & gas and effluent in municipal systems

• Abrasive slurry transfer where centrifugal pumps would erode quickly

• Hygienic and sanitary processes in food, beverage and pharmaceutical production

• Drum and tote unloading where suction lift and dry-run capability matter

• Hazardous-environment fluid transfer where electric pumps create ignition risk
