WASTEWATER
WANGEN PUMPS:
FUTURE-PROOFING WASTEWATER SYSTEMS
City and district councils are increasingly challenged by budgetary constraints and environmental concerns.
Wangen wastewater pumps offer solutions designed to meet these needs today and well into the foreseeable
future. That’s thanks to low life-cycle costs and some of the most advanced engineering in the world.
Wangen Pumpen, manufacturer of pumps in
the historic German city of the same name,
was founded in 1969. The company has from
its start been driven by a desire for achieving
extreme precision, resilience, and long life in all its
products.
It’s a particular source of satisfaction for the
company that a Wangen Pump owned by an
Austrian client, Mr Maier, has run for 35 years
without the need for repairs.
Prime Pump chose Wangen pumps for the
New Zealand wastewater market, specifically
because of this superior design and the very low
maintenance.
Ben Petrie, Prime Pump industrial sales manager,
says the brand is very dominant in Europe and is
rapidly gaining acceptance here. Systems have
already been commissioned in this country, and
more are about to come on stream soon.
Ben says that the pumps’ slow running
significantly reduces wear and importantly that
means a lot less downtime. “It’s very reliable, very
efficient and very cost effective. In the wastewater
industry; that’s vital.”
He says the system also enables councils to
customise to meet individual requirements.
The pumps' ingenious modular construction and a
wide range of standardised components, available
for all series, makes customising pumps to meet
individual needs and environments, if not straight
forward - entirely possible.
The Wangen Xpress progressive cavity pump is
designed to minimise maintenance while at the
same time offering maximum operational safety
and low cost of ownership.
This is the first progressive cavity pump with
complete, in-place maintenance, underscoring
Wangen’s position as a market leader.
This means that the system operator is able to
replace all of the pump’s wear parts without the
dismantling of pipe connections that is usually
required, thanks to the unique X-Lift quick change
system developed by Wangen. This design
enables the easy removal of the rotor and stator,
and the entire drive section (cardan shaft & joints)
in just four simple steps. That means less space
and time is needed during servicing.
Only four standard tools are required for routine
maintenance. Even the shaft seal can be replaced
in just a few actions, and once again, like the rotor
and stator, the seal change can be carried out
with the pump still in place. Due to the compact
dimensions of the pump series, all work can be
performed by just one person.
A unique feature of the Wangen Xpress pump
is that complete in-place maintenance will not
impact operational safety. The in-place solutions
previously available in the market are provided with
an additional pressure port in the pump’s interior.
They enable a rotor and stator replacement in
installed condition, but also increase the risk of
leakage. By contrast, thanks to revolutionary
X-Lift discharge flange, the design of the Wangen
Xpress pump is completely without sealing joints.
Consequently, failures cannot be caused due to
the leakages.
The final step, in wastewater treatment, are
Wangen high performance hopper feed pumps.
These are ideal when conveying demanding
products, pumping to large heights and distances
and when high dosage accuracy is required.
They are utilised in numerous industries all over
the world, including wastewater treatment plants.
The pumps have the ability to transfer dewatered
sewage sludge with a solid content of up to 45%.
Numerous versions and sizes as well as a modular
pump construction ensure that you are able to
obtain a pumping solution that is tailored to your
individual needs.
In many industry sectors, slurries are often
conveyed at high pressure and fast rotational
speeds, or in continuous operation. With
conventional pumps, this high strain frequently
leads to breakdowns due to join breaks, for
example. For this reason, Wangen only use topquality,
robust components across the entire pump
range. Years of optimisation have ensured that
these are designed down to the finest details.
This means Wangen pumps guarantee lowmaintenance
operation which is almost fault-free.
