Wilo Stratos-Pico-25/1-6-130-(ROW) Glandless Circulator Pump – 230v – Single Phase – 61 Ltr/min – OBSOLETE

The Wilo Stratos-Pico-25/1-6-130-(ROW) Glandless Circulator Pump – 230v – Single Phase – 61 Ltr/min – OBSOLETE was developed to provide reliable water circulation for domestic central heating, underfloor heating, and closed-loop cooling systems. Its electronically controlled ECM motor automatically adjusted pump performance to match changing system demand. As a result, it reduced electricity consumption while maintaining consistent circulation and efficient system operation.

Although this model has now been discontinued, many units remain installed in existing heating systems. Additionally, modern Wilo replacement circulators offer higher energy efficiency, improved electronic controls, and easier installation for replacement projects.

Wilo Stratos-Pico-25/1-6-130-(ROW) High-Efficiency ECM Technology

The advanced ECM synchronous motor continuously adjusted pump speed according to heating demand. Furthermore, the integrated electronic controller supported variable differential pressure (Δp-v) control, helping optimise performance for radiator and underfloor heating systems.

Moreover, the pump delivered up to 90% energy savings compared with conventional uncontrolled circulators. Consequently, homeowners and building managers benefited from lower electricity costs and improved overall heating efficiency.

Wilo Stratos-Pico-25/1-6-130-(ROW) Reliable Heating Performance

This glandless circulator delivered a maximum flow rate of 61 Ltr/min while maintaining reliable circulation throughout domestic heating systems. In addition, the compact 130 mm installation length made it ideal for installations where space was limited.

The maintenance-free glandless design eliminated the need for mechanical shaft seals. Likewise, the blocking-current proof motor and automatic deblocking function improved operational reliability and helped prevent pump seizure after long periods of inactivity.

Wilo Stratos-Pico-25/1-6-130-(ROW) Replacement Information

Although the Wilo Stratos-Pico-25/1-6-130-(ROW) Glandless Circulator Pump is now obsolete, it continues to operate in many existing heating systems. Therefore, customers replacing this model should consider the latest Wilo high-efficiency circulator pumps, which provide enhanced electronic controls, lower energy consumption, and improved system compatibility.
