SEW-EURODRIVE sales representative
Willem Strydom elaborates that
its extensive experience and track
record in the wastewater-treatment
innovations
involves removing the sludge with
dewatering machines. Manufacturing
equipment
for
thickening
and
dewatering
applications
is
a
particular area of expertise for the
Wamechsi Group. “We supply turnkey
installations, in addition to consulting
and after-sales services,” Niemand
points out.
The main reason that we have been so successful in
this industry to date is largely due to our innovation
and the reliable product range.
industry means it is able to offer
flexible and highly reliable total
solutions. “Our industrial gear units
are ideal for applications where a
high performance level is required
for mixing and agitating liquid or
paste-type
substances.”
Apart
from wastewater treatment, this
also includes chemicals, food-and-
beverage, and mining.
“With
aerator
and
mixing
applications, our projects and
engineering teams have to double-
check all of the loads and bending
moments. These loads are supplied
to us by the client, based on their
designs. We then ensure that the
gearboxes selected are suited to
the application at hand,” Strydom
highlights.
This goes hand-in-hand with
commissioning and maintenance
support as required. SEW-EURODRIVE
employs a special program designed
specifically to determine if the
gearbox selection is adequate, based
on the loads and bending moments.
This is particularly important when
it comes to aerators and mixers. It
therefore selects the optimal gearbox
for the application at hand. 
Established in 1997, the Wamechsi
Group has transformed into the largest
manufacturer of its kind in South
Africa. Its extensive manufacturing
capability includes state-of-the-art
laser and plasma cutting, CNC lathes
and milling machines, submerged-arc
and robotic welding, and ancillary
equipment such as twenty-four 5t
overhead cranes. The group acquired
its first products from the German OEM
treatment process at a wastewater-
treatment
plant,
ranging
from
mechanical screens to washers and
screw presses that wash and compact
the material to be removed. Ancillary
mechanical equipment includes screw
pumps, surface aerators, and clarifiers.
The biological aspect of the
treatment process results in sludge
that is processed further by digesters.
