Circulation pump Wilo-Yonos MAXO 25/0.5-7 PN10
Circulation pump Wilo-Yonos MAXO 25/0.5-7 PN 10
The Wilo-Yonos MAXO circulating pump is an electronically controlled device designed for use in heating, ventilation and air-conditioning systems. Thanks to the use of a synchronous motor based on ECM technology and an integrated capacity control system, the pump allows infinitely variable differential pressure control, which guarantees optimal adjustment to the system load
The unit is throttle-free, making it easy to integrate into circulating systems. Standard features include a selectable control mode - constant pressure (Δp-c) or variable pressure (Δp-v), 3 speed stages, an LED display for setting the setpoint and indicating fault messages, and an electrical connector with a Wilo plug. In addition, the pump is equipped with a fault indicator light and a contact for collective fault indication
Thanks to its robust design and high-quality materials, the pump guarantees reliability and durability. Ease of installation is ensured by G 1½ connections on the suction and discharge sides, as well as a standard installation length L0 of 180 mm
