Wet Rotor Circulators

ecocirc PRO High efficiency hot water circulation pumps

Hot water circulation pump, high efficient with stepless variable speed

The ecocirc PRO are highly efficient hot water circulation pumps, which are based on the proven shaftless spherical motor design with ECM technology and permanent magnet. This design combines the best efficiency and low noise at an affordable price.

The ecocirc PRO features includes automatic ventilation mode and heat insulation shell as well as optional clock and/or temperature setting.

Variants of these circulation pumps are suitable for use in houses and multiple occupancy dwellings. They comply with Drinking Water Regulations, and by circulating the drinking water they provide effective protection against legionella. Warm water circulation ensures that warm water is immediately available even when the furthest positioned tap is turned on.

The new, stepless adjustable models Lowara ecocirc PRO 15-1 require a maximum of only 3-9 W! For all applications where a higher head or more flow is needed, the Lowara ecocirc PRO 15-3 up to three meters head or a flow of 1500 l/h. The power consumption is only 4-27 W.

Highly efficient circulating pump – saving up to around 90% of electricity costs compared to a 25 W standard pump

Replacement guide

Eventually old pumps need to be replaced. With the new high efficiency ecocirc range, it pays back to replace a 5 year old pump fixed speed pump already today. The difference in efficiency makes the investment profitable already after two years (depending on operation time).
