Product description
The Wilo-Yonos MAXO circulating pump is a glandless unit designed for the highest efficiency and precise control of operating parameters. Thanks to the electronic control and integrated capacity control system, infinite differential pressure control is possible, ensuring optimum adjustment to the load of heating, ventilation and air-conditioning systems
The unit uses a synchronous motor compatible with ECM technology, resulting in high energy efficiency and reliable operation. Standard functions are available to select the type of pressure control: constant-pressure mode (Δp-c) and variable-pressure mode (Δp-v)
Standard functions
- Choice of regulation type: Allows the pump operation to be optimally matched to the load by choosing between constant-pressure (Δp-c) and variable-pressure (Δp-v) regulation.
- Three speed stages: Allows the motor to maintain constant speed, which contributes to the stability and efficiency of the unit's operation.
- LED display: Allows you to set the setpoint and indicates messages about possible failures.
- Electrical connector with Wilo plug: Guarantees fast and trouble-free installation and reliable electrical connection.
- Fault indication system: Equipped with an indicator light and a contact for collective fault indication.
- Flanged versions: 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, and for pumps DN 80/DN 100 - flange PN 6 (design PN 16 according to EN 1092-2) for counter-flange PN 6.
