Starting Methods

There are a variety of starting methods for Fire Pump Controllers, each with a different answer for how much current will be drawn when the motor is initially started. The more the reduction of the inrush current, the more complex the equipment must be.

The links below will cover each starting method beginning with the most basic: the Across the Line controller.

Across the Line
Wye Delta Closed

Part Winding
Softstarting

Primary Reactor
Autotransformer

Wye-Delta Open
Variable Speed

Variable Speed Controller, Single or Dual Source

Inrush Current:
150%

Motor Starting Operation:
Our model MCV controller dynamically regulates the motor speed and system pressure for smooth pressure adjustments due to changing flows or suction pressure variations. They also provide both Soft Starting and Soft Stopping to reduce or avoid start up water surges and shut down water hammer.

Motor Starting Current:
Controls the starting current to a maximum inrush of 150%.

Motor Starting Torque:
Controls the torque to at least 100%.
