Product Overview
AquaMotion AMH3K-7N Hot Water Recirculation Pump
The AquaMotion AMH3K-7N is designed to deliver hot water quickly at all points between the water heater and the farthest fixture. This pump ensures hot water availability on demand.
On-Demand Activation
The ON-DEMAND system allows homeowners to activate the pump manually using a wireless controller. It operates without a timer, making it more energy-efficient by reducing electricity consumption.
Efficient Temperature Control
An integrated Aquastat sensor activates the pump when water temperature drops below 85°F. The pump will run until the water reaches 105°F, ensuring a quick and consistent hot water supply.
Multiple Controller Options
AquaMotion offers various wireless controllers to suit your needs. You can choose from a wireless button (AMK-WBR), wireless wall switch (AMK-WSR), or motion sensor (AMK-MSR). Up to four additional controllers can be added for enhanced convenience.
Simple and Effective Water Recirculation
This pump works with standard hot water heaters and two-pipe plumbing systems. It creates a loop from the water heater to the faucet, recirculating unused hot water and eliminating waste. As a result, you get hot water faster and reduce water waste.
Water Savings
The AMH3K-7N can save up to 12,000 – 15,000 gallons of water per year in homes with multiple faucets. No more waiting for hot water and wasting precious resources.
Eco-Friendly Design
The pump's moving parts are housed in a "Green Eco Cartridge Design." This design allows for field serviceability—simply remove the rotor, flush with water, and reinstall for maintenance.
