Product description
The Wilo-Yonos MAXO circulating pump is a glandless unit with the highest efficiency, designed for use in heating, ventilation and air-conditioning systems. Thanks to the electronic control and integrated efficiency control system, stepless differential pressure control is possible, which allows you to optimally adjust the operating parameters to the current needs of the system
The device is characterized by high energy efficiency and precise operation. As standard, functions are available to select the type of regulation: maintaining a constant differential pressure or variable pressure regulation. In addition, the LED display allows you to set the setpoint and quickly identify messages about possible failures
Main functions and advantages
- Electronic control: Allows infinite differential pressure control for optimal adjustment of unit operation to system load.
- Choice of control mode: Can be set to fixed-pressure or variable-pressure mode.
- LED display: Facilitates the setting of the setpoint and indicates the status of the unit.
- Robust design: Grey cast iron body, impeller made of PPS material with glass fiber additive, stainless steel shaft and graphite bearings ensure long-lasting operation.
- Electrical connector: Standard equipped with a Wilo brand plug for easy installation and reliable electrical connection.
- Fault signaling system: An indicator light and a contact for collective fault indication increase the safety level of the unit.
