Diaphragm Pumps

Diaphragm pumps are used to move liquids in applications such as agricultural spraying, chemical handling, liquid transfer, and other industrial fluid handling processes. The right pump depends on the liquid, required flow rate, operating pressure, and application.

Diaphragm pumps use a flexible diaphragm that moves back and forth to draw liquid into the pump chamber and then push it out through the discharge side. This positive displacement action allows the pump to move a controlled volume of liquid through the system.

A diaphragm pump uses a flexible diaphragm to move liquid, while a centrifugal pump uses a rotating impeller to create flow. Each has different flow, pressure, and operating characteristics, so the right choice depends on the application. Shop for centrifugal pumps.

Yes, some diaphragm pumps can be used for compatible chemicals. Always check that the diaphragm, seals, valves, and other wetted materials are suitable for the specific chemical before use.

An electric diaphragm pump uses an electric motor to operate the pumping mechanism. Mid-South Ag's range includes electric diaphragm pumps in 12V DC, 115V AC, and 230V AC configurations for compatible applications.

A demand pump typically uses a pressure switch to start and stop as system pressure changes. A bypass pump allows liquid to recirculate within the pump when demand decreases. The correct option depends on how the system is designed to operate.

Choosing the right pump involves checking the required flow rate, operating pressure, power supply, inlet and outlet connections, liquid compatibility, and intended application. If you're replacing an existing pump, checking the manufacturer and model number can also help identify a compatible replacement.

Yes. Diaphragm pumps are commonly used for agricultural spraying and liquid application. The pump's flow rate, pressure, materials, and specifications should be matched to the sprayer and liquid being applied.

Maintenance requirements vary by model but can include inspecting the diaphragm, valves, seals, oil, connections, and other wear components. Always follow the manufacturer's recommended maintenance schedule and replacement procedures.
