El Sid Brushless DC Pump for 20W Module

Ivan Labs
El-Sid Brushless DC Pump (PV Powered)
For Solar Hot Water Circulation

El-Sid pumps are used in PV powered circulation for closed-loop solar water heating systems. They can be used to pump water or glycol solutions and can also be used for hydronic radiant floor space heating in off-grid or uninteruptible battery backup situations. These high quality pumps feature seal-less magnetic coupling to the impeller. There is no seal friction, no seal wear, and no chance of seal leakage. El-Sid pumps use brush-less motors that are maintenance-free.

El-Sid Advantages

• For solar water heating (PV-direct)
  • Use a small, inexpensive PV module (photovoltaic panel) to power the pump. No battery or electronic controller is used. There is no wiring to the building's electrical system.
  • Sun-synchronous operation: pump speed varies with sunlight, corresponding to the available heat in the collector—natural automation!
  • This principle has proven highly reliable in solar water heaters since the early 1980's.
