PMP-WSP25 Circulation pump Wilo Stratos PICO-Z 25/1-4 180mm 230V PN10 4m

Wilo Stratos PICO-Z 25/1-4, electronically controlled high efficiency pump. Maintenance-free glandless circulation pump with screwed connection, blocking-current proof synchronous motor using ECM technology (up to 90% energy saving compared to an uncontrolled pump) and built-in electronic power control for variable differential pressure control. Can be used for all HVAC applications (+2 °C to +110°C). Control mode can be selected in accordance with the radiator/underfloor heating application.

Standard-equipped with:

• Preselectable control modes for optimum load adjustment: • Δp-c (differential pressure constant), can be combined with Dynamic Adapt control function
• Automatic setback operation
• Integrated motor protection
• Operating and fault display (with error codes)
• LC display with precise menu navigation
• Display of the instantaneous power in Watts
• Display of the cumulative power consumption in kilowatt-hours
• Reset function for resetting the electricity meter or for resetting the settings to the factory settings
• “Hold” function (key lock) for disabling the settings
• Minimal consumption only 3 W
• High efficiency, TÜV tested (the certificate can be seen at www.wilo.com/legal)
• Compact design
• Automatic deblocking function
• High starting torque
• Venting routine for automatic venting of the rotor chamber
• Equipped as standard with a thermal insulation shell

Pump housing made of cast iron (or bronze depending on the type), impeller made of polypropylene, stainless steel shaft with metal-impregnated carbon friction bearings.
