Diaphragm Metering Pumps

(330 products)

Here at Commercial Industrial Supply, we are pleased to offer our customers a wide selection of metering pumps, including these diaphragm pumps. Diaphragm pumps, which are often called "membrane pumps," use a rubber, teflon, or thermoplastic diaphragm to facilitate positive displacement. The diaphragm repeatedly expands and contracts, which forces fluid through the one-way check valves. These valves are built into the pump and prevent fluid from flowing in the wrong direction.

Additional Diaphragm Pump Information

As mentioned before, diaphragm pumps use positive displacement to move fluid from one place to another. Put simply, this means they trap some amount of fluid and push it into the discharge pipe. The volume within the diaphragm remains constant, which is what gives the fluid constant flow within the pump. It may sound like a complicated process, but the mechanics are simple enough so any repairs can be made quickly and easily.

Our pumps come from the best manufacturers in a variety of materials and sizes. The flow rates also vary, with some precision pumps with under 10 GPH capacities and others with 40+ GPH ratings. The range of pumps we carry allows us to cater to almost every need you might have, so fill out a quote request today to get in contact with our skilled and knowledgeable sales team!
