Wilo-Yonos MAXO-D high-efficiency pump, electronically controlled. Double wet rotor pump, synchronous motor according to ECM technology and integrated power regulation for modulating differential pressure control. Can be used in all heating, ventilation and air-conditioning applications.

 

Each pump can be operated in individual mode (main/standby operation). To enable automatic exchange of the pumps in the event of a blockage, a suitable switchgear is required on site.

 

Standard with:

• Preselectable control modes for optimum load adaptation: ?p-c (constant differential pressure), ?p-v (variable differential pressure)
• 3 speed stages (n = constant)
• LED indicator for setting the setpoint and displaying error messages
• Electrical connection with Wilo connector
• Error signal and contact for cumulative blocking signal
  
   

With flanged pumps - versions with flange:

• Standard version for DN 32 to DN 65 pumps: combined flange PN 6/10 (PN 16 flange according to EN 1092-2) for PN 6 and PN 16 counter flanges
• Standard version for DN 80 / DN 100 pumps: PN 6 flange (sized PN 16 according to EN 1092-2) for PN 6 counter flange.
