Stuart Turner Pulse 32/120-F220 Commercial Circulator Pump

Stuart Turner Pulse 32/120‑F220 Commercial Circulator Pump

This is a robust, electronically controlled variable‑speed flanged circulator engineered for professional hydronic applications including hot‑water heating, air‑conditioning and ventilation systems. Part of the Stuart Pulse cast iron flanged range, it continuously monitors system pressure and flow then automatically adjusts performance to deliver efficient, energy‑compliant operation and reliable circulation in demanding plant‑room environments.

Key Features

• Adaptive variable speed control supporting automatic, proportional pressure, constant pressure and constant speed modes for precise system performance.

• Automatic night mode to reduce power consumption during off‑peak periods.

• ECM permanent magnet motor technology for high energy efficiency and ErP compliance.

• Automatic venting cycle to help minimise trapped air and improve ongoing reliability.

• Durable cast iron construction with carbon bearings designed for commercial plant‑room environments.

• Flanged DN32 connections and 220 mm fitting length for secure inline system integration.

• Built‑in protections including over‑current, over‑temperature and over‑voltage safeguards.

• LED control panel for straightforward configuration and status feedback.

• ErP compliant to meet current energy efficiency regulations.

• Two‑year manufacturer’s warranty for installed confidence.

Performance Summary

The Pulse 32/120‑F220 delivers dependable circulation for commercial hydronic systems:

• Maximum head (closed valve): approximately 12.1 metres, providing strong pressure delivery where required.

• Maximum flow rate: around 10.8 m³/h, enabling efficient fluid movement in larger circuits.

• Maximum working pressure: up to 10 bar, suitable for high‑pressure commercial heating systems.

• Water temperature range: –10 °C to +110 °C, supporting typical hot‑water system conditions.

• Minimum inlet pressure: 0.05 bar at fluid temperatures <75 °C.

These performance characteristics support efficient, reliable circulation across commercial HVAC and hydronic heating networks where adaptive control and energy efficiency are priorities.
