EL-SID Brushless Water Circulators
Cat. No. AEE-75.7218

These tiny brushless, magnetic-drive circulators can be driven by PV modules or 12-volt batteries for closed-loop circulation in solar water heating systems and individual loops of radiant floor heating systems. Use of several small pumps in a radiant floor system allows each loop to be controlled by a different thermostat. Model 10PV-12 is designed to be powered by a 10- to 20-watt PV module in an open loop system and can pump 3.3 gallons per minute at no head, and 1/2 gpm at 2.5 feet of head, at 17 volts input. A 20-watt module should be used for glycol systems. It can circulate water in a well designed solar water heating system with two 4 x 10 collectors. Model 10B-12 is designed to be battery powered and has the same specifications at 12 volts. 10B-24 is designed to operate on a 24 volt battery system. 20B-12 uses more power to provide more flow and more head. 20PV-12 requires 40 watts of PV and is ideal for pumping glycol through 3 or more collectors. It is a good idea to face the module to the east to help this pump start in the morning. Dimensions: 4" x 4" x 5". 30,000-hour life expectancy.
