Air Driven & Mechanical Diaphragm Pumps
Air Driven & Mechanical Pumps are a positive displacement pump that uses one or two flexible diaphragms to create a temporary chamber that draws and expels materials such as fluid, from the chamber. The pump is driven by an air motor using an sliding piston or a gearbox that is powered by an electric, diesel or petrol engine. With engine driven mechanical diaphragm pumps, the flow rate can be adjusted in these pumps either by adjusting stroke length, gear box ratios or motor speed. With air driven diaphragm pumps, the flow rate can be varied by adjusting the pressure of the compressed air supply.
With access to over 240 local and international pump manufacturers, and our own brand UltraFlow, General Pump Company has the range and expertise to help you source and, if needed, identify the right air driven or mechanical diaphragm pump and equipment for your needs.
What are Diaphragm Pumps
Diaphragm pumps, also known as membrane pumps, are a type of positive displacement pump that utilizes a flexible diaphragm and a set of check valves to move fluids. They are highly versatile and capable of handling a wide range of fluids, including those that are highly viscous, corrosive, or contain abrasives. The operation of a diaphragm pump involves the diaphragm flexing back and forth to create a vacuum that draws fluid into the chamber and then expels it through the discharge valve during the return stroke. These pumps are known for their self-priming capabilities, leak-free operation, and gentle handling of shear-sensitive fluids. Commonly found in industries such as chemical processing, water treatment, food and beverage, pharmaceuticals, and construction, diaphragm pumps are valued for their durability, safety, and ease of maintenance. Their ability to operate in harsh environments and manage complex fluids makes them indispensable in many applications.
Key Features of Diaphragm Pumps:
- Versatile: Capable of handling a wide variety of fluids, including those with high viscosity, corrosive chemicals, and abrasive slurries.
- Self-Priming: They can prime themselves, making them suitable for applications where the pump is located above the fluid level.
- Leak-Free Operation: The diaphragm acts as a barrier between the fluid and the moving parts, reducing the risk of leaks.
- Gentle Pumping Action: Suitable for shear-sensitive fluids due to the gentle pumping mechanism.
- User friendly: Diaphragm pumps can operate without liquid passing through the pump and no damage will occur to the pump, unlike may other types of pumps that have mechanical seals, rubber & plastic components that can be affected by heat when there is no liquid passing through the pump.

How do Air Driven & Mechanical Diaphragm Pumps Work?
Air Driven & Mechanical Diaphragm Pumps is a heavy duty pump that utilises a mechanical gearbox to actuate the diaphragm mechanism thereby controlling the flow rate. It operates in a similar manner to the principle used in an internal combustion engine.
