Xylem Updates Popular ecocirc BASIC and PREMIUM Pumps

Posted: Friday 14th July 2017

Xylem, a leading global specialist in water technologies, has updated its Lowara brand ecocirc BASIC and PREMIUM residential circulators.

Suited to HVAC and domestic applications, the pumps have been fitted with an improved cast iron pump housing, which, thanks to the cataphoresis coating, is fully resistant against corrosion. The new housing not only improves reliability and efficiency, but also performance, with the pumps now capable of functioning in the most demanding conditions and environments.

Designed with a spherical rotor, the ecocirc BASIC and PREMIUM pumps have only one single bearing and are shaftless, operating both efficiently and quietly. The ECM technology combined with the permanent magnet rotor also works to reduce electricity usage and water consumption, as well as further increasing the pumps operating life.

In addition, both ecocirc BASIC and PREMIUM come fitted with an internal temperature sensor as standard, measuring the electronic component temperature directly. If overheating occurs, the pump reduces speed accordingly, and will only resume when adequate cooling levels have been met.

Thanks to the patented anti-block technology, the pumps are also protected from blockages caused by magnetite and sludge: The magnetic chamber can be separated from the flow if the rotor gets blocked, while emergency software vibrates the rotor prevent further build-up.

For ease of installation, a universal plug is provided, meaning not only can the pumps be integrated into any heating system, no tools are required for assembly. Operators using the ecocirc PREMIUM also benefit from the ability to fix the pump into any position by turning the stator via the screw ring, making installations simple even in the most restricted environments.

Controlled with one, easy-to-use switch, the ecocirc BASIC has two control options; stepless fixed speed and automatic proportional pressure control. Operators can also quickly purge the pump of air, removing it from the inner of the pump, by turning the switch towards the air purge symbol for more than five seconds. In addition, the ecocirc PREMIUM offers an extra control feature, the automatic constant pressure control, which is best suited to underfloor heating applications. Thanks to the installation of a digital Multi-Display, users of the ecorcirc PREMIUM benefit from further monitoring capabilities, with the display highlighting power consumption, pump head, and flow rate, as well as flagging errors and warning messages to give users total transparency over their pump's performance.
