These pumps are also known as air-operated double diaphragm pumps. In simple terms, two flexible diaphragms move back and forth inside the pump. As one side draws fluid in, the other side pushes fluid out.

Because of this design, the pump can handle a wide range of liquids. For example, it can support chemical transfer, wastewater handling, viscous fluids and liquids with small solids. In addition, this pump type can run dry for short periods without the same risk as many standard pumps. This makes it useful where fluid supply may change during operation.

Another benefit is its simple air-powered design. As a result, these pumps are often chosen for sites where electric power is not ideal or where safe fluid handling is important. The range can support many applications across industrial, chemical and specialist fluid transfer duties. However, the right model depends on the liquid type, flow rate, pressure and materials needed.

Pedrollo Distribution can help review your requirements. First, we look at the fluid, site conditions and duty. Then, we recommend a suitable option for your application.
