Product description
Stuart Turner Pulse 25/100-180 Commercial Circulator Pump
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.
Key Features
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.
Performance Summary
