Drive Handles Water and Wastewater Applications

abb1104

ABB has launched its first water and wastewater industry-specific drive as a cornerstone product. Designed for extremely fast and easy set-up, the new ACQ550 drive now is available from 1 to 550 hp. The drive seamlessly integrates as a NEMA1, drip-proof NEMA-12, or outdoor-rated NEMA-3R solution.

It comes with a library of pre-programmed start-up assistants for commissioning submersible, centrifugal, or positive-displacement pumps, and application macros for configuring inputs, outputs, and parameters.

Based on the Affinity Laws of physics, which define the relationship between pumps and the power they require, the new drive is suited for the simplest pumping application through the most demanding, resulting in significant cost savings.

On centrifugal pump applications, for example, the power requirement of the pump varies by the cube of the speed. Electronically reducing the pump speed by 20 percent via the drive will typically cut energy costs in half.
