Appalachian 120 Self-Priming Surface Pump – 12″ / 9510 GPM / 285 HP

DAE Pumps Appalachian 120 Self-Priming Surface Pump is a heavy-duty centrifugal dewatering self-priming pump with a 12-inch discharge. They provide a maximum flow rate of up to 9510 GPM with their 285 HP diesel engine. The Appalachian 120 is capable of automatically priming to 24.6-feet of suction lift from dry and can pass solids up to 3.5-inches. These heavy-duty pumps extend a range of industries from applications like dewatering mines and construction sites, removing floodwater, and a variety of other municipal applications. The Appalachian pump provides the non-clogging performance, reliability, and ease of use you need.

The Appalachian 120 surface pumps comprise of an air separator unit and a vacuum pump, offering rapid automatic priming. Even with suction heights of several feet, these tools rapidly evacuate the air from the suction pipe and start to pump. In addition, the semi-open impeller is suitable for pumping liquids with solids in suspensions.

The Appalachian 120 is part of the Appalachian Series of self-priming surface pumps, which offer a variety of sizes, flow rates, speeds, and more to match your needs.
