These pumps can handle challenging solid materials

| By Mary Page Bailey and Gerald Ondrey

The Vortex Series of pumps (photo) are designed for handling abrasive wastes. Using a recessed impeller design, the series combines the efficiency characteristics of a self-priming pump with the solids-handling capabilities of a chopper pump. This makes it suitable for applications that need to pass solids while also handling flows to meet the application’s high total dynamic head (TDH) and gallons per minute (GPM) requirements. Recessed impellers assure that only about 15% of the solids that pass through the pump come into contact with the impeller, according to the manufacturer. Combining this impeller design with a vacuum-assisted priming chamber allows the pump to move both solids and fluids efficiently. The priming system also ensures rapid and unattended re-priming, and the run-dry lubrication system avoids premature failure of the seal and rotating assemblies. — Pioneer Pump, a Franklin Electric Co. brand
