Why This Product

Wet-Rotor Construction — No External Bearings

Wet-rotor design runs the rotor in the pumped fluid — the fluid lubricates and cools the rotor bearings directly. No external bearings, no bearing lubrication, no bearing replacement. Service life of 20,000+ hours in normal HVAC service.

AutoAdapt — Automatic Speed Optimisation

AutoAdapt technology continuously adjusts pump speed to match the actual heating demand of the system — reducing energy consumption by 30-50% compared to fixed-speed circulators in typical residential and commercial heating systems.

IE5 Ultra-Premium Efficiency

IE5-rated permanent magnet motor exceeds the requirements of IE4 Super Premium. At typical HVAC partial-load operating points, IE5 efficiency is maintained at speeds well below the design point — unlike induction motors that lose efficiency at reduced speed.

Compact In-Line Design

Compact in-line design fits directly into existing pipework — no baseplate, no special support, no change to pipe routing. Flanged and threaded connection options for direct retrofit of existing circulators.

Low Noise — Suitable for Residential Installation

Wet-rotor design with no mechanical bearings in air produces significantly less noise than dry-rotor pumps. Grundfos circulators are rated for residential mechanical room and under-floor installations where noise is a concern.

Grundfos GO App Integration

Compatible with the Grundfos GO mobile app for wireless commissioning, pump setting, and energy data review — no special tools or proprietary interface equipment required for installation, commissioning, and service.

Important Notices
Electrical Requires correctly rated supply — 440-480V, 3-Phase, 50, 60 Hz. Install with correctly rated circuit protection and motor starter.
Temperature limits Do not exceed max fluid temperature 194°F or max ambient temperature 131°F. Operating outside these limits will damage seals and motor insulation.
Dry running Do not run dry. CME 5-5 pumps use the pumped fluid to lubricate the shaft seal — dry running destroys the seal within seconds. Install dry-run protection on all automatic installations.
Maintenance Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance intervals. Contact PumpStop for documentation.
