Flender gear units play KEE role May 1st 2011 Wastewater treatment solution
provider, KEE Process has specified
Flender gear units from Siemens
Drive Technologies for a number of
years, due to their reliability, low
maintenance requirements, high
torque and ongoing low power
demands.
One of KEE's latest UK projects
was the installation of rotating
biological contactors (RBCs),
modular treatment plants for
treatment of medium scale capacity.
The 4.5m units incorporate Flender
FZG gear units (size H3DH11),
combined with Motox units (size
KAF108K4-1LA9) and highefficiency
Siemens eff1 motors (size
113-4KA). This combination drive
design was selected to achieve high
ratios for low-speed operation –
around 1rpm output speed – with
4kW power and 63,500Nm gearbox
rating.
KEE Process contracts engineer,
Alastair McInnes said the units were
virtually silent in operation, due to
being driven by direct coupled
geared motors."We cannot fault
these gear units and geared motors;
their performance and reliability is
very impressive.We also obtain good
after-sales service support from
Siemens, which is an important part
of our contracts for customers all
over the world." More articles from Siemens Industry Automation & Drive Technologies (Flender): |
