This is a single-head variable speed circulator designed for use in commercial hot-water heating, air-conditioning and ventilation systems. Engineered as part of the Pulse range, it offers electronically controlled performance to dynamically adjust pressure and flow according to system demand, supporting efficient, energy-compliant operation in professional building services environments.
Variable speed operation with automatic, proportional pressure, constant pressure and constant speed control modes for adaptive system performance.
Automatic night mode for reduced energy consumption during low-demand periods.
ECM permanent magnet motor technology for high efficiency and compliance with ErP energy regulations.
Automatic venting cycle to minimise trapped air and improve reliability.
Robust cast iron construction with carbon-graphite bearings for durability in commercial plant environments.
LED control panel for clear status feedback and simplified configuration.
Built-in protection systems for over-current, over-temperature and over-voltage conditions.
ErP compliant to meet modern energy efficiency standards.
2-year manufacturer’s warranty for peace of mind.
The Pulse 32/80-180 delivers reliable circulation performance tailored to the needs of commercial hydronic circuits:
Maximum head (closed valve): approximately 8 metres.
Fitting length: 180 mm standard in-line dimension for ease of integration.
Connection size: G 2 threaded union connections for robust plumbing integration.
These performance characteristics make the Pulse 32/80-180 suitable for maintaining flow and pressure in demanding heating, cooling and ventilation networks where energy efficiency and control adaptability are priorities.
Power supply: 230 V AC, single phase, 50 Hz (typical for commercial installations).
Duty rating: Continuous (S1) for sustained operation.
Maximum working pressure: Up to 10 bar.
Temperature range: Suitable for typical hot-water heating systems (approx. -10 °C to +110 °C).
Bearings: Carbon-graphite type for extended service life.
Enclosure protection: Adequate for internal plant room conditions.
