Circulation pump Wilo-Yonos MAXO 40/0.5-16 PN6/10
Circulation pump Wilo-Yonos MAXO 40/0.5-16 PN6/10 2120648
Wilo-Yonos MAXO 40/0.5-16 PN6/10 circulating pump is a high-quality device designed for use in heating and cooling systems. Thanks to its efficiency, reliability and modern technological solutions, it is the ideal solution for demanding customers looking for the best products on the market
The built-in length of 250 mm allows easy and quick installation of the pump in any location, while the motor power consumption (P1) of 0.8 kW provides sufficient power for efficient operation of the device. The normative diameter of the connection on the supply side (DN 40) allows trouble-free connection to heating or cooling systems
The Wilo-Yonos MAXO 40/0.5-16 PN6/10 operates over a wide range of medium temperatures from -20 °C to +110 °C, while withstanding ambient temperatures from -20 °C to +40 °C. Failure indication is built in as standard, and the LED display indicates the set head. The pump allows infinite capacity adjustment depending on the selected operating characteristic - constant pressure (p-c) or variable pressure (p-v) mode
Additional features include integrated full motor protection, automatic venting of the impeller chamber, automatic return to the set operating parameters after restoration of voltage (in case of a failure with a power outage), and an impeller unlocking function after a period of downtime. A convenient WILO plug with pull-out protection and simple setting of operating parameters with a red Wilo dial further enhance the utility of the unit. Cataphoresis coating (KTL) on the body effectively protects against corrosion
