Circulation pump Wilo-Yonos MAXO 40/0.5-8 PN6/10
Highest efficiency pump Wilo-Yonos MAXO 40/0.5-8 PN 6/10
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 changing operating conditions
The unit is throttle-free, making it easy to install and integrate into circulating systems. The pump is characterized by high efficiency, and its functionality is complemented by such features 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 display failure messages
- Electrical connector with Wilo plug
- Fault indication lamp and contact for collective indication
- Flange versions are available for flanged pumps, including a PN 6/10 combination flange for pumps DN 32 to DN 65 and a version for DN 80/DN 100
