Robust pre-assembled
panel systems for
pumping applications
T
he range of pump panel systems
from EM not only reduce
energy costs, but also conserve
water and maximise productivity,
comments Automation Manager
William Cameron. Additional benefits
are automatic ‘sleep’ and ‘wake’ functions,
and enhanced motor and pump protection
such as Class II surge protection.
The standard features of the irrigation
pump panels are: a panel mount
isolator, drive and control circuit
breakers, power and control terminals,
manual off/automatic selector switch,
run and trip indication, cooling fans and
vents, and a rotary setpoint selector.
Typical applications are irrigation,
domestic water supply, fish farming,
water livestock, solar-powered
fountains, sprinklers, misters, and
soakers, ground dewatering for
excavation, and construction sites.
The standard features of the solar
or photovoltaic pump panels are: a
multi-status indicator lamp, an on/
off selector switch, DC fuse protection
(including a spare), no-flow input and
underload protection, and maximum
power point tracking software and
manual override.
“Using Huba’s 528 pressure
transducers, and Delta’s CP2000
pump-purpose drive, creates a robust
combination that is exactly what
the industry demands,” Cameron
stresses. The drive’s customised
keypad layout means operational
data is displayed on one screen,
while sub-menu settings are easy to
navigate. simplify installation, commissioning,
and servicing. With virtually every panel builder
in South Africa using ubiquitous
technology distributed exclusively by
EM, the supplier continues to build
on its strategy of providing the right
product at the right price, for the correct
application and specification at hand.
The pump panel systems are enclosed
in weather-tight sheet-metal enclosures
that are available in various sizes and
variations, depending on the particular
requirements of the installation. The
uncluttered panel layout means there
is sufficient working space in order to Preconfigured Variable Speed Drives
(VSDs) reduce the energy drawn by
the pump motor controlling the speed,
while maintaining a constant pressure on
the line. This is critical in terms of overall
efficiency, as even a small reduction in
speed result in significant cost-savings. Cameron concludes that the niche
irrigation and solar pump panel system
market is aimed at not only diversifying
into additional markets, but to be able
to offer the full benefits of its latest
technology and products to the full
spectrum of South African industry.
