Digitel Brushless Pumps

English

These leakproof, brushless, magnetic drive circulating pumps are designed to pump water between solar water heating collectors and tanks or other closed loop, low flow pumping applications. They can be battery powered or operated directly from a solar module, without batteries or controls, to pump water when the sun shines on the solar module.

The brighter the sun, the faster the water is pumped. There are two models to choose from; one for operation on a 12 volt nominal PV module or 12 volt battery and one for operation on a 24 volt nominal PV module or 24 volt battery.

These pumps have a 3 speed electronically commutated, high efficiency brushless motor with a 50.000 hour life expectancy. As mentioned before it works well as a circulating pump betvveen a tank and solar collector in a domestic hot water system. It also functions well as a circulating pump in a radiant floor heating system.

In Europe they are used on inland navigation for already 30 years. Hundreds of these pumps are integrated on oil-fïred heating systems.
