DC Circulating Pumps

D5-38 Vario

VARIABLE SPEED
HIGH EFFICIENCY MAGNETIC DRIVE DIRECT CURRENT CIRCULATORS

The EcoCirc electrically commuted spherical motor design offers many benefits over other pump styles. The Laing design operates on extremely low power input at a specified nominal voltage from 8 to 24 volts; the spherical permanent magnet eliminates impeller slippage which makes the Laing pump up to 40% more efficient than a standard induction motor. The motor has no shaft and therefore no shaft seal that is a wear point and potential leak path. Pump operation is virtually silent, with a low 35 db noise level. The brushless motor has a lifetime in excess of 50,000 hours when operated at nominal voltage and can be powered directly by solar panels, battery or other DC power sources. The unique screw ring design for this series of pumps allows for changing motors without disturbing the pump housing piping.
