Self-Priming Diaphragm Pumps

The self-priming diaphragm pumps are particularly effective in emergencies where it is necessary to handle sludge, wastewater, abrasive liquids, or water with a high presence of solids. They are used in cases of floods, sewer breaks, cleaning of manholes, emptying of tanks, and operations in industrial or urban areas that are difficult to access. Aquageo selects Varisco and Caffini diaphragm pumps with configurations suitable for emergency response. Their operating principle allows them to work even with aerated liquids and materials that could compromise a traditional centrifugal pump. The units can be supplied on trolley, skid, or trailer, complete with pipes and accessories for quick commissioning.
