ABB water/wastewater drives
ACQ550, 1 to 550 HP
A reliable system is critical
to protecting, supplying
and recycling water. What
you choose matters. The
world trusts you to make
good decisions and you
take that responsibility
seriously. We’ll help
safeguard your system to
the value and dependability
you demand.
With this in mind, we designed our variable
speed AC drives specifically for Water/
Wastewater environments and applications.
These devices are available, as standard, for
panel-mounting or factory direct NEMA-1,
drip-proof NEMA-12 or outdoor-rated
NEMA-3R enclosures.
A water industry start-up assistant resides
within the intuitive, full graphic display panel to
aid in commissioning submersible, centrifugal
or positive displacement pumps. This control
panel can also be mounted remotely, or on
the cover of the drive, and used to upload,
store and download parameters in multiple
drive setups.
troubleshooting, the drive uses a realtime clock, which allows for accurate
time stamps on faults, resets and more.
Two integral option slots, that can be
configured for additional relay outputs (i.e.
drive status indications, timed or pump
staging applications) or a variety of different
communication bus adapters, are at your
Cost savings
applications, the power requirement of the
pump varies by the cube of the speed.
Electronically reducing the pump speed by
20% will typically cut energy costs in half.
Designed for water
The ACQ550 - which ranges from 1 to 550
HP - is well-suited to meet your needs, from
the simplest pumping applications, through
the most demanding.
We designed our solutions to give you the
most flexible motor control performance
through two standard modes: Scalar (V/Hz)
for typical pumps and Sensorless Vector for
the more demanding applications. Through
either of these, you will have accurate speed
control of any standard induction motor.
Application control
Save energy by applying variable electronic
speed control to your pumps and pumping
systems. These savings can be achieved
The extensive library of pre-programmed,
water-specific application macros allows
rapid configuration of inputs, outputs, and
parameters to maximize convenience and
minimize start-up time. To simplify
over bypass or valve-operated flow control,
traditional diesel driven systems or across the
line operations. The Affinity Laws of physics
define the relationship between pumps and
the power they require. On centrifugal pump

System reliability, pump efficiency and a
suite of industry-specific controls enable
you to successfully maintain a reliable
water cycle management system.
