The GRUNDFOS PM START Automatic Pressure Control Kit is an intelligent pump control device designed to automatically manage start and stop operations of water pumps based on water demand. It converts a standard pump into a fully automatic pressure system, making it ideal for residential, villa, and light commercial water supply applications.

The unit automatically starts the pump when pressure drops (water tap opened) and stops the pump when flow stops (tap closed). It also includes built-in protection features such as dry-run protection, preventing pump damage when no water is available.

The PM START is designed for clean water systems and supports stable pressure operation within a typical cut-in pressure range of around 1.5 bar (model dependent), ensuring smooth and reliable water delivery.

It is commonly used with booster pumps, surface pumps, and small water supply systems where automatic operation is required.
