The benefits of NOV Mono’s
EZstrip technology have been
highlighted by a new order
from a Danish wastewater
treatment plant. When
sourcing pumps for a new
sludge dewatering process,
maintenance engineers at the
Odense WWTP in Southern
Denmark opted for 8 Mono
EZstrip cake pumps and 16
Compact C Range progressing
cavity (pc) pumps.

The company says the
decision was based on the
reduction in maintenance the
pumps offer, together with
speed of delivery from Mono.

These benefits led the plant’s
engineers to specify Mono’s
EZstrip and Compact C
Range pumps for use on new
polymer dosing equipment.

“When we were invited to
tender for pumps on the
sludge dewatering process,
we took an EZstrip
demonstration pump to the
plant,” explains product
manager Michael Roug, from
AxFlow A/S, Mono’s
distributor in Denmark who
supplied the pumps. “We
explained how the pump
could be disassembled, deragged
and maintained insitu,
all in a fraction of the
time that process takes with a
normal pc pump. Coupled
with the fact that Mono was
competitive in terms of cost
and speed of delivery, this
made it an easy decision for
the maintenance engineers.”
The pumps were ordered
in a variety of sizes for use on
different parts of the process.

They can reduce the time
needed to replace a rotor,
stator, coupling rod and drive
train by up to 95%, cutting
maintenance down to 30min.
