×Chilled water no problems

The electronics are separated from the pump to prevent condensation problems when pumping chilled liquids.


Two analogue inputs for 4-20mA and 0-10V signals and one temperature probe.


The built in dry run protection stops the pump and prevents damage if it runs without water.

×Keep it hot

A moulded insulation shell keeps the temperature of the pumped liquid (and the surroundings) where it should be.

×Visible in dark plant rooms

Clear display with large figures and symbols makes it easy to read the values, even in the dark.

×Low cost of operation

Your operation costs are kept to a minimum thanks to a high efficiency ECM motor and hydraulics.

×Easy to operate

With only four logically placed buttons, it’s easy to set up and operate the new ecocirc XL.


The Lowara ecocirc XL and XLplus – single and twin head high efficiency circulators in cast iron, stainless steel or bronze for hot and cold HVAC applications

At Xylem we believe in products that do their job when expected and are easy to install, commission, operate and service. When it comes to circulators, that means: high efficiency, robust design and high precision manufacturing as well as well thought through controls and communication. A product for many years of trouble free operation. This is exactly what the ecocirc XL and XLplus will offer.

The ecocirc XL and XLplus range offer full hydraulic coverage with only 34 sizes, making the selection process easy.

The main features are:

  • Different operation modes, including differential and proportional pressure, differential temperature, automatic night set back
  • Communication capabilities, including WiFi, Modbus and Bacnet
  • Quick installation and start up with few steps (watch the videos to see how simple it is under the “Installation and set up” tab)

Benefit from full performance coverage with only a few models.

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).
