Since this Metron diesel fire pump controller is compact and lightweight, it works great for commercial purposes. It meets the standards NFPA20, UL218, and FM 1321/1332 for diesel engine fire pump controllers.

Metron Electric Fire Pump Controller

Their dedication to quality is not confined to diesel variants; you get even more with Metron electric fire pump controllers

Metron MPT electric fire pump controllers are basically the latest microprocessor-based controllers. As the name suggests, they have been designed to operate with electric motor driver fire pumps

The controller triggers whenever there is a drop in pressure in the water mains or in the case of other demand signals. When this period is over, the motor can be stopped manually or electrically, depending on various scenarios

Fire pump controllers that come with integral automatic transfer switches are beneficial in bringing emergency power to the fire pump in the event of power loss

This arrangement would have taken a lot of space with traditional designs, but Metron solved it with its latest series of models having 32” wide dimensions.

Besides, the series provides various controller starting methods, so the limitation eliminates altogether

The starting methods included with this are MPT300 – Across-the-line starting, MPT420 – Part Winding, MPT430 – Wye-Delta Open Transition, MPT435 – Wye Delta Closed Transition, & more.

No wonder Metron is known for constantly enhancing the efficiency and technical proficiency of its electric fire pump controllers. You can find different models housing different arrangements and features to suit various applications and requirements.
