Is a premium cast iron circulator engineered to deliver adaptable and energy-efficient performance in commercial and light industrial hot water heating, cooling, ventilation, and hydronic circulation systems. As part of the official Stuart Pulse range, this single-head variable speed pump continuously monitors system pressure and flow, adjusting its operation automatically to maintain optimal hydraulic performance with low energy consumption, a solution well-suited to modern mechanical plant installations.
Variable speed control with automatic, proportional pressure, constant pressure and constant speed operating modes to match system demands.
Automatic night mode for energy savings during low-load periods.
ECM permanent magnet motor technology offering high efficiency and compliance with ErP energy directives.
Automatic venting cycle to reduce entrapped air and improve reliability.
Robust cast iron housing with corrosion-resistant finish designed for commercial plant environments.
Continuously rated (S1) for sustained operation in demanding systems.
Built-in protection against over-current, over-temperature and over-voltage conditions.
LED control panel for intuitive setup and status feedback.
ErP compliant to meet modern efficiency regulations.
The Pulse 25/100-180 is designed to maintain flow and pressure across commercial hydronic circuits, adapting dynamically to changes in system demand:
Maximum head: approx. 10 metres closed valve.
Maximum flow capacity: typically up to ~11.8 m³/h (subject to system conditions).
Maximum operating pressure: up to 10 bar.
Operating modes: automatic, proportional/constant pressure, constant speed and night mode.
These performance attributes support efficient circulation in multi-zone systems and contribute to energy-efficient HVAC and heating installations.
Power supply: 230–240 V AC, single phase, 50 Hz.
Duty rating: Continuous (S1).
Fitting length: 180 mm standard commercial dimension.
Connection type: G 1½ threaded union.
Enclosure protection: IP42 suitable for internal plant environments.
Pump body material: Cast iron with corrosion-resistant coating.
Bearing type: Carbon/graphite type for durability and smooth operation.
Warranty: 2 years manufacturer’s warranty.
