Product description
Circulation pump Wilo-Yonos MAXO 80/0.5-12 PN6 is a modern device with the highest efficiency, dedicated to heating, ventilation and air conditioning systems. The model with a flange connection is equipped with an automatic unblocking function, which guarantees reliability and operational safety. The device offers three modes of operation, allowing smooth adjustment of performance to current operating conditions, so you can use pressure regulation in both constant-pressure (p-c) and variable-pressure (p-v) modes
Key features and advantages
- Automatic impeller unblocking: The function allows for the removal of any blockages after a period of downtime, which contributes to a trouble-free startup.
- Three operating modes: Allows the pump's operating characteristics to be adjusted to the plant load - a choice between constant pressure (p-c) and variable pressure (p-v) modes.
- LED display: Allows monitoring of the set head and quick recognition of emergency signals.
- Automatic venting function: Ensures efficient removal of air from the impeller chamber to increase pump performance.
- Built-in full motor protection: Ensures protection against damage and return to set operating parameters when voltage is restored in case of failure.
- Flange design: Allows 1:1 dimensional interchangeability with older, standard pumps, making it easy to upgrade installations.
- Cataphoretic coating (KTL): On the pump body prevents corrosion from condensation, extending the life of the unit.
