Circulation pump Wilo-Yonos MAXO 25/0.5-12 PN10
Highest efficiency pump Wilo-Yonos MAXO 25/0.5-12 PN 10
The Wilo-Yonos MAXO circulating pump is a state-of-the-art electronically controlled device for use in heating, ventilation and air-conditioning systems. Thanks to the use of a synchronous motor based on ECM technology and an integrated capacity control system, the pump allows infinitely variable differential pressure control, which allows optimal adjustment to the system load
The unit is throttle-free, making it easy to install in circulating systems. As standard, it offers a number of features to enhance comfort and reliability, including
- Selectable control mode: Δp-c (constant differential pressure) or Δp-v (variable differential pressure)
- 3 speed stages (n = constant)
- LED display for setting the setpoint and informing of any failures
- Electrical connector with Wilo plug
- Fault indication lamp and contact for collective indication
- Suitable flange versions are available for flanged pumps
- For pumps DN 32 to DN 65 - combination flange PN 6/10 (flange PN 16 according to EN 1092-2) for counter flanges PN 6 and PN 16
- For pumps DN 80/DN 100 - flange PN 6 (design PN 16 according to EN 1092-2) for counter-flange PN 6
