Circulation pump Wilo-Yonos MAXO 50/0.5-8 PN6/10
Highest efficiency pump Wilo-Yonos MAXO 50/0.5-8 PN 6/10
The Wilo-Yonos MAXO circulating pump is a state-of-the-art electronically controlled device for use in all heating, ventilation and air conditioning systems. Thanks to the use of a synchronous motor based on ECM technology and an integrated capacity control system, it allows stepless differential pressure control, which guarantees optimal adjustment to the system load
The unit is throttle-free, making it easy to install in circulating systems. Numerous features are available as standard to enhance operating comfort and reliability
- Selectable control mode: Δp-c (constant differential pressure) or Δp-v (variable differential pressure)
- 3 speed stages (n = fixed)
- LED display to set setpoint and display failure messages
- Electrical connector with Wilo plug
- Fault indication lamp and contact for collective indication
- Different 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
