PRIME PUMP: THE PUMP
VERSION OF HARE VS
TORTOISE – SAME RESULT
Slow-running, high
performance Wangen
pumps offer outstanding,
dedicated wastewater
management solutions thanks to
low life-cycle costs and some of the
most advanced engineering in the
world.
These pumps could provide some
much-needed answers for the
increasing number of under-pressure
New Zealand cities whose ageing
wastewater infrastructures are
now reaching the end of their lives.
Already deployed very successfully
in one major city, Wangen delivers
a much more cost-effective and
enduring solution compared to the
all-too-common, and ultimately very
expensive, fall backs of short-term
repairs or the relatively short-life
options of competing pump brands.
Sourced from Germany by innovative
New Zealand company Prime Pump,
hard-wearing Wangen progressive
cavity pumps are already very
well-established in Europe. But
far-sighted locals are also catching
on. That’s according to Ben Petrie,
Prime Pump key account manager.
“Once clients have tried Wangen,
they’ll never go back.”
His view is backed-up by users in
other industries such as the agricultural
effluent sector.
One key client says almost as soon
as Prime Pump brought Wangen
into New Zealand, he thought it
was worth a look. And it’s more
than rewarded his confidence. In
two years, his company has seen
some “fairly catastrophic” failings
with other pumps of the same age,
but none with German-engineered
Wangen.
“The whole Wangen design is
better,” he says highlighting the
durable Cardan universal joint, in
particular.
“They’re a really nice pump. And
being slower running is a real
advantage. It’s quiet, performs very
well and it’s just logical that anything
running slower will last longer.”
There is a very solid history behind
Wangen’s success. Wangen
Pumpen, which manufactures the
pumps in the historic German city
of the same name, located on the
Bodensee, was founded in 1969.
The region has a legacy of manufacturing
that goes back to the Middle
Ages and Wangen, as a company,
has continued that venerable
tradition. At the same time, it’s
driven by a desire for continual
improvement, extreme precision,
resilience, and a dedication to
ensuring long life in all its products.
Prime Pump are committed to
travelling the world to find the
best quality pumps, designed and
manufactured to suit New Zealand
conditions, and they back them up
with guarantees and service. They
say Wangen has more than met
their expectations, not least because
of its extreme hardiness. (There
are well-documented examples of
pumps running intervention-free for
over three decades. One Wangen
pump owned by an Austrian client,
Mr Maier, has run for 35 years,
without the need for repairs.)
The extended life of Wangen pumps
comes from some significant design
advantages over and above others
in the market.
One of those keys to the Wangen
pumps’ performance is the Cardan
joint; a critical design feature.
This universal joint-like system is
superior to the conventional pin
joint. The pin joint wears, often
rapidly, resulting in characteristic
“sloppiness” and ultimately the need
for regular replacement. In contrast
the Cardan joint operates smoothly
and seamlessly, lasting the lifetime
of the pump. The design, which
has the same diameter as the rotor
ahead also avoids constraint in the
flow, and the problem of settling,
which effectively removes the
issues related to fibres becoming
wrapped around the shaft.
A one-piece cartridge mechanical
seal, filled with oil, rather than a
traditional two- piece mechanical
seal, is also far easier and quicker
to fit while the oil, again, helps
extend the life of the seal.
An extra bearing housing between
the gear box and pump adds
additional rigour to the structure
and supports reliable performance.
The system also enables councils
to customise to meet individual
requirements thanks to the pumps'
ingenious modular construction
and a wide range of standardised
components. Available for
all Wangen series pumps, this
makes customising pumps to meet
individual needs and environments,
if not straight forward - entirely
possible.
