This is a single‑head, variable speed flanged circulator designed to meet the demanding requirements of commercial hot‑water heating, air‑conditioning and ventilation systems. Part of the Stuart Pulse Cast Iron Flanged range, this pump continuously monitors and adjust pressure and flow to optimise hydraulic performance while delivering energy‑efficient operation and compliance with current efficiency (ErP) standards. Its robust construction and advanced control capabilities make it suitable for professional plant‑room installations where reliable circulation and flexibility are required.
Variable speed operating modes including automatic, proportional pressure, constant pressure and constant speed for adaptive system control.
Automatic night mode to enhance energy savings during periods of reduced demand.
ECM permanent magnet motor technology for high efficiency and TrP/ErP compliance.
Automatic venting cycle helps prevent air locks and improves continuous reliability.
Robust cast iron body with carbon‑graphite bearings designed for commercial HVAC environments.
Flanged DN32 connections and 220 mm fitting length, ideal for inline integration in pipework.
Built‑in electrical protections including over‑current, over‑temperature and over‑voltage safeguards.
LED control panel simplifies configuration and provides system feedback.
ErP compliant to meet modern efficiency regulations.
Two‑year manufacturer’s warranty for added peace of mind.
The Pulse 32/80‑F220 delivers dependable performance tailored to the needs of commercial hydronic circuits:
Maximum head (closed valve): approximately 8.4 metres.
Maximum flow rate: up to around 12.3 m³/h, depending on system conditions.
