Wilo - Yonos Maxo-D 40/0.5-12 PN6/10 Circulator Pump - 230V - Single Phase - 250mm

The Wilo - Yonos Maxo-D 40/0.5-12 PN6/10 Circulator Pump - 230V - Single Phase - 250mm is a circulator pump designed to circulate water through heating, cooling, or hot water systems.

With single-phase power and 230V supply, it is built to support efficient system movement and dependable temperature control.

High-efficiency pump Wilo-Yonos MAXO-D, electronically controlled. Glandless twin-head pump, synchronous motor according to ECM technology and integrated power control for continuous differential pressure control. can be utilised for all heating, ventilation and air-conditioning applications.

Each pump can be operated in individual operation (main/standby operation). The connection module Yonos MAXO can be utilised for automatic fault-actuated switchover.
