Solar Pumps

Merlin Series M5


Estimated Production Lead Time for M5 Pump is 1 Week.

The innovative Merlin Series pumps are constructed with a stainless steel housing and cap. They are designed to provide a longer pump life, increased strength, and trusted durability. These pumps dissipate heat more effectively than PVC pumps. This thermal protection extends the life of the motor. These pumps are submersible, factory rebuildable, lightweight, and built in the U.S.

API solar water pumps do not require a controller, however the ALC 1275 greatly increases the life expectancy of our aluminum pumps and prevents unnecessary wear and tear on the pump.

Available in these systems: KS08, KS18, KS20, KS22

150 and 200 feet wire rolls are available. There is a $35.00 up charge for each additional 50 feet of wire.
