Wilo Stratos-Pico-15/1-4-(ROW) Glandless Circulator Pump – 230v – Single Phase – 51 Ltr/min – Obsolete

The Wilo Stratos-Pico-15/1-4-(ROW) is a high-efficiency glandless circulator designed for heating and hot water circulation systems. This obsolete model uses a 230 V single-phase electronically controlled ECM motor and provides a maximum flow rate of 51 Ltr/min.

The pump offers a maximum head of 4 m and a 10 bar maximum working pressure. With a 130 mm port-to-port length and G 1 threaded connection, it was designed for compatible compact heating installations, including radiator and underfloor heating circuits.

Electronic Pump Control

The Stratos PICO 15/1-4 supports both variable differential-pressure (Δp-v) and constant differential-pressure (Δp-c) control. The electronic controller adjusts pump operation to system requirements, helping maintain efficient circulation as demand changes. Wilo documentation lists a 1~230 V supply, 130 mm installation length and G 1 connection.

Reliable Circulation for Heating Systems

The maintenance-free glandless construction supports dependable operation with low service requirements. The pump also includes an LCD display for operating information, automatic functions and integrated motor protection. These features made the model suitable for domestic heating and compatible hot water circulation applications.
