ITT Water & Wastewater, UK, is a provider of products, systems and processes
to move, control and treat water, wastewater and other fluids. The company’s
four key product brands are Flygt, Sanitaire, Wedeco and Leopold.
Flygt specialises in heavy duty pumping and mixing technology.
The company has extended its Flygt N-pump range of efficient wastewater
pumps, with the introduction of larger pumps – up to 300kW – suited to heavy
duty applications such as pumping
‘raw’, unscreened wastewater.
The large centrifugal pumps have
self-cleaning impellers, reducing the
risk of them being blocked. This is an
important feature in high volume, raw
wastewater pumping applications.
Steve Gilbert, market manager –
municipal transportation for ITT
Water & Wastewater, said, “The
non-clogging properties of the
Flygt N-pump reduce service call-
outs, help keep maintenance costs
down and ensure pumps continue
to run efficiently over long service
periods. These are all important
considerations for water companies.
There has been a definite need for a
clog-resistant pump in these larger
sizes.”
While the pumps are fully
submersible, they can be installed
vertically dry and are also able to operate within explosive and flammable
environments when fitted with the ‘Ex’ version of the drive unit. Existing Flygt
units can be retrofitted to the Flygt ‘N’ impeller.
In the UK and Ireland, ITT Flygt also provides rental, monitoring and control, and
aftermarket services as part of its total solutions portfolio.
