High efficiency pump Wilo-Yonos MAXO
electronically controlled,
Glandless circulator, synchronous motor according to ECM technology and integrated power control for continuous differential pressure control. Can be used for all heating, ventilation and air-conditioning applications.
Standard-equipped with:
- Preselectable control modes for optimum load adjustment: Δp-c (differential pressure constant), Δp-v (differential pressure variable)
- 3 speed stages (n = constant)
- LED for setting the setpoint and displaying error messages
- Electrical connection with the Wilo plug
- Fault lamp and contact for collective fault signal
For flange-end pumps - flange versions:
- Standard version for pumps DN 32 to DN 65: PN 6/10 combination flange (PN 16 flange according to EN 1092-2) for PN 6 and PN 16 counter flanges
- Standard version for DN 80/DN 100 pumps: PN 6 flange (designed for PN 16 according to EN 1092-2) for PN 6 counter flange
