Diaphragm pumps are positive displacement pumps commonly used in industrial fuelling applications for transferring a wide range of liquids. Their design makes them suitable for handling viscous fluids, abrasive slurries, and even hazardous materials. They operate by using a flexible diaphragm to move fluid, offering excellent suction capabilities and precise flow control. These robust pumps are ideal for dispensing fuels, oils, and other chemicals safely and efficiently.
