Highest efficiency pump Wilo-Yonos MAXO 25/0.5-10 PN 10
The Wilo-Yonos MAXO circulating pump is a state-of-the-art electronically controlled device designed 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 and integrate into circulating systems. Numerous features are available as standard, such as
- Selectable control mode: Δp-c (constant differential pressure) or Δp-v (variable differential pressure)
- 3 speed stages (constant speed operation)
- LED display to set the setpoint and indicate failure messages
- Electrical connector with Wilo plug
- Fault indication lamp and contact for collective indication
- Versions are available for flanged pumps
- Standard 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
- Standard for pumps DN 80/DN 100 - flange PN 6 (design PN 16 according to EN 1092-2) for counter-flange PN 6
