Stuart Turner Pulse 40/80-F220 Commercial Circulator Pump

Stuart Turner Pulse 40/80‑F220 Commercial Circulator Pump 

This is a cast iron, flanged, variable‑speed circulator engineered for commercial heating, ventilation and air‑conditioning (HVAC) applications. Designed to integrate directly into hydronic pipework, this model delivers adaptable and energy‑efficient circulation by continuously monitoring system pressure and flow, then automatically adjusting its operation to match system demand. It combines advanced motor technology, robust materials and multiple control modes for optimal performance in demanding plant‑room environments.

Key Features

• Robust cast iron housing with carbon‑graphite bearings for long‑term commercial use.

• Variable speed control with automatic, proportional pressure, constant pressure and constant speed modes for dynamic performance.

• Automatic night operation mode to reduce energy consumption during low‑demand periods.

• ECM permanent magnet motor technology for efficient operation and compliance with ErP energy efficiency standards.

• Automatic venting cycle to minimise air entrainment and improve reliability.

• LED control panel for intuitive configuration and pump status feedback.

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

• DN40 flanged connections with a 220 mm fitting length, suitable for commercial pipework integration.

• ErP compliant to align with modern efficiency requirements.

• Two‑year manufacturer’s warranty for added assurance.

Performance Summary

This circulator is engineered to provide reliable performance in medium‑to‑large hydronic systems:

• Maximum head (closed valve): approximately 8.4 metres, supporting effective pressure delivery.

• Maximum flow rate: around 12.3 m³/h, allowing efficient fluid movement across larger systems.

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

• Water temperature range: ‑10 °C to +110 °C, compatible with typical hot‑water applications.

• Minimum inlet pressure: 0.05 bar at fluid temperatures <75 °C, enabling consistent operation within system requirements.

These characteristics make the Pulse 40/80‑F220 suitable for demanding HVAC and hydronic heating installations where adaptability, efficiency and dynamic control are priorities.

Technical Information
