Grundfos PM PLUS Automatic Pressure Controller with Adjustable Start Pressure & Dry-Run Protection (1.5–3.0 Bar)

The Grundfos PM PLUS is a sophisticated automatic pressure controller designed to manage the start/stop function of Grundfos and other domestic water supply pumps with precision and reliability. Unlike basic pump controllers, the PM PLUS offers advanced functionality including adjustable start pressure (1.5 to 3.0 bar) and dry-run protection — giving you complete control over pump performance while safeguarding your system.

This intelligent pressure manager ensures consistent water pressure by automatically activating the pump when demand is detected and stopping it when no flow is required. It is equipped with a built-in non-return valve and features automatic restart after temporary power failures, making it ideal for residential installations where uninterrupted water supply is essential.

Built for convenience and durability, the PM PLUS supports 1x115–230V power supply, handles liquid temperatures from 0°C to 60°C, and offers IP65-rated protection. With an integrated gauge and compact design, it's a plug-and-play upgrade for any domestic pressure pump installation needing improved performance, safety, and energy efficiency.
