Self-Priming Diaphragm Pumps

The self-priming diaphragm pumps are suitable for muddy, viscous, abrasive liquids or those with a high presence of solids. They are particularly used in draining difficult excavations, cleaning manholes, wastewater management, and industrial applications where a standard centrifugal pump might clog or suffer premature wear. The Aquageo range includes diesel, gasoline, and electric pumps, portable or mounted on a cart or sled. Thanks to the diaphragm operating principle, these pumps can also work with aerated fluids and withstand harsh operating conditions. Solutions from Atlas Copco and Varisco are available, with configurations selected based on flow rate, suction depth, solid passage, and type of material pumped.
