Diaphragm pumps are widely used across industrial facilities to transfer liquids, chemicals, and slurries where reliable flow control and chemical resistance are essential. Within our Industrial portfolio, John Morris Group supplies diaphragm pumps and fluid handling equipment from globally recognised manufacturers including Masterflex and Cole-Parmer, supporting manufacturing, mining, water treatment, and chemical processing applications.
Diaphragm Pumps
Diaphragm Pumps For Industrial Fluid Transfer And Chemical Handling
Our range of diaphragm pumps supports a wide variety of industrial fluid handling tasks where durability and chemical compatibility are critical:
- Chemical Transfer And Dosing: Diaphragm pumps from Masterflex and Cole-Parmer are frequently used for transferring aggressive chemicals, solvents, and reagents while maintaining leak-free operation.
- Self-Priming Fluid Handling: Many diaphragm pump designs are self-priming and capable of running dry, making them suitable for applications involving intermittent flow or suction lift conditions.
- Industrial Process Integration: Diaphragm pumps are widely deployed in wastewater treatment, pilot plants, pharmaceutical production lines, and chemical processing facilities where accurate fluid transfer is required.
How Diaphragm Pumps Work
A diaphragm pump uses a flexible membrane that moves back and forth within the pump housing. This movement creates alternating suction and discharge cycles, allowing fluid to be drawn into the pump chamber and then pushed through the discharge outlet. Because the fluid is separated from the mechanical components by the diaphragm, these pumps are particularly suitable for handling corrosive or sensitive liquids.
How To Choose The Right Diaphragm Pump
When selecting a diaphragm pump for industrial processes, engineers should consider the following key parameters:
- Flow Rate And Pressure Requirements: Pump capacity must match the required flow rate and pressure conditions of the process system.
- Chemical Compatibility: Wetted materials such as PTFE, stainless steel, or polypropylene must be compatible with the fluid being transferred.
- Power Source: Diaphragm pumps may be electrically driven or air operated depending on the facility infrastructure and safety requirements.
Supporting Equipment For Industrial Fluid Management
Diaphragm pumps are most effective when integrated with compatible system components. These related categories often form part of a complete fluid transfer system:
- Fluid and Gas Distribution: Valves, regulators, and flow control components help manage pressure and direct fluid flow within process pipelines.
- Industrial Filtering and Purification: Filtration systems protect pump internals and downstream equipment from particulate contamination.

Frequently Asked Questions
What Are Diaphragm Pumps Used For?
Diaphragm pumps are commonly used to transfer chemicals, solvents, slurries, and other industrial fluids in applications such as wastewater treatment, chemical dosing, and manufacturing processes.
Are Diaphragm Pumps Self-Priming?
Yes. Most diaphragm pumps are self-priming and can operate even when the pump is not completely filled with liquid, making them suitable for suction lift applications.
Can Diaphragm Pumps Run Dry?
Many diaphragm pump designs can run dry for short periods without damage, which is beneficial for intermittent-duty applications where fluid flow may stop temporarily.
