About Diaphragm Pumps

Diaphragm pumps are versatile, self-priming pumps used to transfer a wide range of fluids, including water, slurry, sludge, chemicals and abrasive materials. Their unique design uses a flexible diaphragm and check valves to create suction and push fluid through the pump, making them ideal for handling viscous, corrosive or solid-laden liquids.

Our hire fleet includes air diaphragm pumps (pneumatic or powered by compressed air), electric diaphragm pumps and petrol-driven diaphragm pumps. Highly resistant to clogging, diaphragm pumps can handle fluids with suspended solids, making them well-suited for construction, mining, industrial and wastewater environments. The air-operated double diaphragm (AODD) pumps are especially popular for hazardous or explosive environments since they require no electricity.

One of the key advantages of diaphragm pumps in Australia is their ability to run dry without damage, making them a reliable choice for intermittent or variable flow applications. Their compact and portable design also allows for easy relocation around the site.
