Highest efficiency pump Wilo-Yonos MAXO 50/0.5-9 PN 6/10
The Wilo-Yonos MAXO circulating pump is a state-of-the-art electronically controlled device for 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 infinite differential pressure control, which guarantees optimal adjustment to the changing load
The unit is throttle-free, making it easy to install and integrate into circulating systems. The pump is characterized by high efficiency and reliability, as well as low noise levels and long design life
Standard features available
- Choice of control mode for optimal adjustment to the load
- Δp-c - constant pressure mode
- Δp-v - variable pressure mode
- 3 speed stages (constant speed operation)
- LED display to set setpoint and display failure messages
- Electrical connector with Wilo plug
- Fault indication lamp and contact for collective indication
- For flanged pumps, versions are available
- For 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 DN 80/DN 100 - flange PN 6 (design PN 16 according to EN 1092-2) for counter flange PN 6
