Franklin Electric 3AMH Series Horizontal Multistage Pressure Pump with Pressure Switch & Tank 

The Franklin Electric 3AMH Series Horizontal Multistage Pressure Pump with Pressure Switch & Tank is a premium stainless steel pressure system designed to provide consistent and reliable water pressure for domestic and light commercial applications. Built with Franklin Electric’s proven multistage technology, this system delivers superior performance, efficiency and quiet operation for homes, irrigation and water supply systems.

Each package includes a high-efficiency 3AMH stainless steel multistage pump coupled with a mechanical pressure switch and an accumulator tank (available in 8L, 18L, 35L, or 60L configurations). The pressure switch automatically starts and stops the pump based on system pressure, while the pre-charged tank reduces cycling and ensures smooth, steady water delivery. This combination offers long-term reliability and energy savings across a variety of water applications.
