Stuart Turner Pulse 40/80-F220 High-Efficiency Flanged Circulator Pump - DN40, 8m Head, 230V for Commercial Heating

The Stuart Turner Pulse 40/80-F220 High-Efficiency Flanged Circulator Pump 47415 is a robust, variable-speed cast iron pump designed for commercial heating, air-conditioning and ventilation systems, featuring ECM technology and automatic performance adjustment for maximum energy efficiency.

Product Description

The Stuart Turner Pulse 40/80-F220 is a single-head flanged circulator with DN40 connections and a 220 mm port-to-port length. It continuously monitors pressure and flow, automatically adjusting speed to the selected operating mode (automatic, proportional pressure, constant pressure or constant speed). Built with a cataphoresis-coated cast iron body, stainless steel shaft and carbon bearings, it is ideal for hot water heating, chilled water and glycol mixtures. The pump is ErP compliant (EEI ≤ 0.23) and includes insulation shell, shrouded connector and 1.3 m cable for straightforward installation.
