Wide range of materials
Our range of metallic materials
extends from simple grey cast iron
and chrome-nickel steel to highly
acid-resistant materials such as
Duplex, Hastelloy and titanium for
different conveying tasks. Ceramics
and plastics are offered for aggres-
sive and abrasive applications. Our
elastomers range from highly
abrasion-resistant natural rubber,
to oil-, acid- and alkali-resistant
elastomers as well as Aflas and
Viton. For products in which
elastomers cannot be used because
of high temperatures or for reasons
of durability, a substantial number
of solid-based stators made from
plastics or metallic materials are
available.
(See pages 20 to 23)
Broad range of applications
The pumps are primarily used with
media that have the following
features:
 Free of solids to containing solids
up to 6" / 150 mm (max.)
 Low to high viscosity (1 mPas –
3 million mPas)
 Thixotropic and dilatant
 Shear sensitive
 Abrasive
 Non-lubricating and lubricating
 Aggressive (pH 0 – 14)
 Adhesive
 Toxic
Various conveying elements
Four different rotor/stator geome-
tries variations provide the design
that is optimally adapted to your
specific task.
(See page 18 and 19)
Wide variety of shaft seals
The range of mechanical shaft
seals includes simple seals with and
without quench, double-acting seals
arranged back to back or in tandem,
and cartridge seals. For specific
applications, stuffing-box packing,
lip seals, and special seals are
available. A pump with a magnetic
coupling is available for use with

. . . and conveys
 substances with consistencies from runny to pasty, with or without
solid content.
Housing in FSIP®
design
with inspection cover
The FSIP®
design of the suction housing includes an
inspection cover which is the main differentiator from
the standard design yet the housing dimensions remain
unchanged. All installed NEMO®
BY/SY pumps in
the sizes from NM 045 to NM 105 can be upgraded
without complication. After this upgrade, you can fully
service the pump while it is installed. All wetted parts
are easily reachable. All wear parts can be accessed and
replaced in less than half the time.
Inspection cover
The inspection cover is secured by only 5 screws which
can be removed without special tools.
Stator with iFD technology
The stator consists of a reusable two-part stator
housing and an exchangeable elastomer part. The
benefits of the new technology are reduced starting
torques, higher degree of efficiency, prolonged
lifetime, easier and faster change of the wear part,
with environmentally friendly disposal. In combination
with the FSIP®
suction housing design, the rotor/stator
can be changed simply and quickly outside the pump
without pre-tensioning, after the stator housing has
been opened.
In fact, the rotating unit can simply be lifted out
leaving the pump open from flange to flange.
“Service length“ is no longer required since the pump
has a much shorter footprint. Relatively long progress-
ing cavity pumps can be installed with fewer mainte-
nance concerns. This is also valid when a standard
stator is being used.

Shaft sealing
A single acting mechanical seal in cartridge design (SiC
faces) is standard for this FSIP®
pump design, which can
be easily replaced through the large inspection opening.
Other options upon request.
Block design
The drive is flanged directly to the pedestal of the pump,
resulting in compact dimensions, low total weight,
constant axial heights irrespective of the construction
type and size of the drive. The pump requires low
maintenance, is easy to service, and is economical.
Rotor
In wear- and corrosion-resistant designs, various
materials on request.
Cartridge joint and
rotor head
For the pump in FSIP®
design, the rotor screw may be
ordered separately as a spare part. You change only
the worn part and keep the rotor head in combination
with the cartridge joint so you will save the joint
disassembly time.
Drive train and sleeve coupling
Removing the inspection cover from the FSIP® pump
allows access to a sleeve coupling which joins the rotor
to the coupling rod. Here, only one screw has to be
removed to split both elements from each other.

Sludge Cake Brochure NPA · 312
The aBP-Module®
consists of
a top hopper with two inner
spoked wheels. The spoked
wheels are located close to the
hopper walls, creating the effect
of “moving hopper walls“ which
produces a shearing effect in the
medium. The speed difference
of the spoked wheels, which is
independently adjustable, creates
the required shearing effect,
to consistently prevent bridge
building inside the hopper. The
structured surface of the spoked
wheels assist in product agitation.

up to 33 ft / 10 m. The immersion tube length can be modified by extend-
ing the pump housing, by adding a suction pipe or by combining the two.
This pump is used to empty open barrels and containers. It is fitted with
a clamp to be suspended from a crane. Immersion depth up to 10 ft / 3 m.
Performance
Depending on the specific application, various models/immersion variants
are available. The immersion depth is adapted specifically to the application.
NEMO®
Immersible Pumps are used to empty barrels, containers, tanks, sedimentation tanks, pits etc.
and where space is restricted, where there is a risk of cavitation or where there is very low NPSH.
These pumps are also used to empty containers holding materials that are hazardous to water or the
environment for which standard emptying via a flange on the bottom of the container is not permitted.

Depending on pump size, speed and immersion depth (33 ft / 10 m), an
additional support guide is available to secure the pump to the bottom or
to the wall near the bottom. Removal of the pump from a full tank is
possible because the guide units are self-centering and secure the pump.
Suction is reset upon pump re-insertion. In the variant with discharge
connection below the mounting position, the discharge connection of the
pump is below the tank lid. The product is either piped to the outside
vertically through the lid via a 90° elbow or horizontally through the tank
wall. This minimizes the dead space in the pump housing thus reducing
the overall height of the pump above the tank lid.

Operating method and conveying
principle in NEMO PUMPS®
with
different rotor/stator geometries
Modular system
NEMO®
Pumps belong to the group of rotary positive displacement pumps.
The two conveying elements are the rotor and the fixed stator, in which the
rotor eccentrically turns.
All four pump geometries have the same outer dimensions that allows a
modular design where – apart from rotor and stator – all other components
are identical. When a change in flow rate or pressure is required, installed
NEMO®
Pumps can be adapted to the new operating conditions by simply
changing rotor and stator.

Development
Elastomer research & development
is resident at NETZSCH. At its
in-house laboratory and in close
collaboration with selected materials
suppliers established over many
years, NETZSCH develops and tests
elastomer blends and optimizes
them to meet specific customer
requirements.
We offer each customer the opti-
mum quality of elastomer for the
media to be conveyed in terms of
abrasion resistance, temperature
range, dynamic load and chemical
resistance – something other
suppliers cannot offer. By only using
original NETZSCH spare parts we
can guarantee the pumps you
purchase remain reliable.
Our 60 years of experience in a wide
range of industries and processes
and 40 years of experience devel-
oping and manufacturing elasto-
mers for NEMO®
pumps has led to
the development of complex
bonded parts made of glass fiber,
metal and elastomer for the casing
liners of our new generation of
TORNADO®
T2 rotary lobe pumps.
Production
To meet the growing demand for
our pumps and the associated
demand for spare parts, NETZSCH
invested in a new 43,055 ft² / 4000 m²
production facility in Waldkraiburg
to produce elastomer parts using
the latest production methods and
the latest product standards.
Along with five extruder sets for
manufacturing conventional tube
stators, injection molding machines
and presses were acquired to
facilitate the manufacture of
iFD-Stators®
, lobes and casing
liners for rotary lobe pumps.
Specific requirements in oil
production and transfer
NETZSCH stators stand out with
their long service life, leading to a
significant reduction in operating
costs. This applies in particular to
the difficult operating conditions in
oil production.
Not only for elastomer development
but also for optimal material
selection, specific bore hole and
fluid conditions have to be consid-
ered for oil and gas operations.
NETZSCH pumps can be used as
multiphase pumps in this market
because gas-oil-water mixtures and
various solids can be conveyed
simultaneously or alternately.
For this reason, we have developed
special elastomer mixtures, for
conveying these phases in changing
and variable concentrations.
Additional challenges placed upon
these mixtures can include the
fluctuating and sometimes very high
temperatures, high differential
pressure up to 4,350 psi / 300 bar
between the suction and pressure
side, very aggressive gases (such as
H2
S and C02
) or the presence of oils
(with high aromatic content).

Having the right joint in your NEMO®
pump has a
decisive impact on operational reliability and life-cycle
costs. The optimum joint selected depends on the
application, the operating conditions and the conveyed
media. To achieve the optimum performance of a
NEMO®
pump, additional joint adaptations can be made
to better address individual conditions.
B Universal Pin Joint
The NEMO®
universal pin joint is the
standard joint for NEMO®
industrial
pumps due to its simple design and
outstanding degree of reliability.
The joint has a very long service life,
because it is oil-filled and sealed
using a NEMO®
SM®
seal. The joint
can also be used without the seal at
extremely high temperatures and
flow rates where elastomers are not
acceptable. The joint, has a mini-
mum number of components and
can be easily dismantled for
maintenance.
V Pin Joint
The operational characteristics of
the NEMO®
V pin joint are similar to
those of the B pin joint, but it has a
longer service life under tough
operating conditions because of
hardened bushings, which are fitted
into boreholes in the coupling rod
and the rotor/drive shaft head. The
V pin joint with hardened bushings
is easy to remove for maintenance.
H Sanitary Pin Joint
This open, patented pin joint has
been developed specifically for use
in NEMO®
hygienic pumps. The
joint has no crevices or dead space.
It is polished and easy to clean.
The hygienic pin joint is made in
accordance with the US 3-A Sanitary
Standards.
NEMO®
universal joints
THE RIGHT JOINT FOR EVERY APPLICATION

25
Flextec Flexible Rod
This flexible rod is wear- and
maintenance free because there are
no components moving against
each other as in other joint types.
Neither lubrication nor seals are
required. The flexible rod is suitable
for high pressures and high temper-
atures. It is free from crevices and
dead spaces which allows the
flexible rod to be used for pumping
highly sensitive products in aseptic
conditions. It is designed in accor-
dance with the US 3-A Sanitary
Standards.
Gear Joint (double sealed)
The patented gear joint was
designed for extremely arduous
industrial applications involving
constant pump running, frequent
stop/starts or shock loads. It is
kinematically designed so that the
torque and axial loads are borne by
separate elements within the joint.
The joint is oil-filled and hermetically
sealed by two seals which are resist-
ant (compatible) to the lubricant
and to the pumped substance. Filling
the space between the two seals with
oil allows the use of the joints at
pressures up to 180 psi / 12 bar.
Specially designed gear joints are
available to handle up to 1,450 psi /
100 bar.
Z Double Seal Pivot Joint
For the greatest flow rates and
pressures possible, where torques
and axial loads are at their highest
(in drive train size NM 125SY and
above), NEMO®
pumps are fitted as
standard with a cartridge type
precision pivot joint. This joint is
oil-filled and hermetically sealed
with two seals that are resistant
(compatible) to the lubricant and
to the pumped substance. It is
qualified for continuous operation.
A special design with balanced seal
is available for extremely high
pressures.
