“Full Service in Place“ Pump service without removing the pump from the system
The NEMO® Progressing Cavity Pump in FSIP® design is available…
in sizes NM 045 to NM 105 for flow rates from 8.8 to 880 gpm / 2 to 200 m³/h for differential pressures from 90 psi / 6 bar (1 stage) up to 180 psi / 12
bar (2 stages)in various materials, from steel to chromenickelsteel, various other
materials on requestwith various stator elastomers, from highly abrasionresistant natural
rubber, to oil, acid, and alkaliresistant elastomers, to Aflas and Vitonin all 4 geometries, S, L, D, and P to be customized optimally to your
application
. . . and conveyssubstances 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 twopart stator housing and an exchangeable elastomer part. The benefits of the new technology are reduced starting torques, higher degree of efficiency, prolonged lifetime, and easier/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 pretensioning and 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, the pump has a much shorter footprint – relatively long progressing cavity pumps can be installed with much less of a maintenance concern. This is also the case when a standard stator is being used.

Shaft sealing
A singleacting, cartridge design mechanical seal (with 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 corrosionresistant 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.

Operational Characteristics and Conveying Principle ofNEMO® Pumps in Different Geometries
Modular Design S/L Geometry
NEMO® Pumps belong to the group of rotary positive displacement pumps. The conveying elements consist of the rotor which rotates within the fixed stator.
All four pump geometries have the same outer dimensions. This modular design was established so that, apart from rotor and stator, all other components are identical. If 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.
The single helical screw/rotor has a circular cross section, an extremely long pitch and large thread depth which oscillates when the rotor is turned within the fixed stator. The cross section of the stator is the same profile as that of the rotor, however, the stator is a 180° internal twin start thread. As a result of the 1/2 ratio lobe geometry, cavities are formed between the rotor and stator when the two are put together. The turning movement of the rotor the progressing cavities between rotor and stator transports the fluid in a smooth and continuous manner from the suction side to the discharge side of the stator. The flow rate is determined by the pitch of the rotor/stator, the
diameter, eccentricity and the speed of the pump. The pressure capability depends on the number of stages and the differential pressure per stage up to 85 psi / 6 bar. The 2stage NEMO® Pump in S geometry can reach a differential pressure up to 180 psi / 12 bar with a flow rate of 100%. A singlestage NEMO® Pump in L geometry, has the same outer dimensions as the 2stage pump in S geometry and the same diameter and eccentricity but a pitch double that of the S geometry rotor/stator. This pump configuration produces a flow rate of 200% when compared to the S geometry at a differential pressure of up to 90 psi / 6 bar.
S Geometry
� Very smooth conveyance � Compact dimensions despite high number of stages
� Large cross sections of rotor inlet � Low flow velocity � Low NPSHr � Conveyance of compacted products possible
� Conveyance of large solid particles
L Geometry
� Greater volumetric efficiency/long service life due to long seal lines between rotor and stator
� Compact dimensions along with high flow rates
� 1/2 lobe � Double stage
� Flow rate: 100% � Differential pressure: 180 psi / 12 bar � Multistage design available for pressures up to 4,350 psi / 300 bar
� 1/2 lobe � Single stage � Flow rate: 200% � Differential pressure: 90 psi / 6 bar
17
D/P Geometry
The twin start helical rotor has an elliptical cross section, a long pitch and large thread depth. It moves within a circular eccentric rotation inside the fixed stator, the form of which is the same geometry as the rotor, however, the stator is a triple start internal thread with 120° interval starts. As a result of the 2/3 ratio lobe geometry, cavities are formed between the rotor and stator when the two are put together. The turning movement of the rotor creates the progressing cavities between rotor and stator which transports the fluid in
a smooth and continuous manner from the suction side to the discharge side of the stator. The flow rate is determined by the pitch of rotor/stator, elliptic diameter and eccentricity and the speed of the pump. The pressure capability depends on the number of stages with the differential pressure being up to 90 psi / 6 bar per stage. In D/P geometry the cavities are approximately 75% of the size of the S/L geometry however they open twice per revolution compared to once per revolution in 1/2 stage geometries. Therefore D/P geometry
rotors/stators have a 50% increase in the flow per revolution compared to S/L geometry. The 2stage NEMO® Pump in D geometry can reach differential pressures of up to 180 psi / 12 bar at a flow rate of 150% over that of the S geometry. A singlestage NEMO® Pump in P geometry, has the same outer dimensions as the 2stage pump in D geometry, the same ellipse and eccentricity but a pitch double that of the D geometry rotor/stator. Therefore the pump produces a flow rate of 300% over that of the S geometry at a differential pressure of up to 90 psi / 6 bar.
D Geometry
� Extremely compact dimensions despite high pressures and flow rates capabilities
� Almost pulsation free conveyance � High metering accuracy
P Geometry
� Compact dimensions in conjunction with very high flow rates
� Almost pulsation free conveyance � High metering accuracy � Good volumetric efficiency/long service life due to long seal line between rotor and stator
� 2/3 lobe � Double stage � Flow rate: 150% � Differential pressure: 180 psi / 12 bar � Multistage design available for pressures up to 4,350 psi / 300 bar
� 2/3 lobe � Single stage � Flow rate: 300% � Differential pressure: 90 psi / 6 bar

Elastomer research and development is in-house at NETZSCH. At our 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.
Developing new blends Manufacturing blends
We offer each customer the best 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 dependable.
Our 60 years of experience in a wide range of industries and processes and 40 years of experience developing and manufacturing elastomers for NEMO® pumps has also 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 / 4,000 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 also acquired to facilitate manufacture of iFDStators®, 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 developmentbut also for optimal materialselection, specific bore hole and fluid conditions have to be considered for oil and gas operations. NETZSCH pumps can be used as multiphase pumps in this market because gasoilwater mixtures and various solids can be conveyed simultaneously or alternately.
Extruder with stator for oil production Injection molding machine for iFDstators®Press with casing liners for TORNADO® T2
For this reason, we have developedspecial elastomer mixtures, for conveying materials in variable and changing concentrations.Other challenges we consider are the fluctuating and sometimes very high temperatures of the conveyed materials and the high differential pressure (up to 4,350 psi / 300 bar) between the suction and pressure side, as well as the very aggressive gases (such as H2S and C02) or oils (with high aromatic content) that can be present.

Functioning principle
The TORNADO® rotary lobe pump is a positive displacement pump. The pumping action is generated by the contrarotation of two rotors within the pump chamber which are synchronized externally. The product enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.

Ease of service
“Full Service-In-Place” instead of ”Maintenance-In-Place”
Servicing a rotary lobe pump has never been so easy and without the need for any special tools. Rotors can be removed and replaced very quickly because they are not bolted or keyed to the shafts within the pump head but fixed with quickfit, nonproductwetted taper lock assemblies that are positioned and accessed from outside the pump head. The geometry of the rotors allows independent fitting and removal. There are no keys dictating unique rotor positioning which results in faster, easier, and cleaner rotor removal and replacement. For rotor
synchronization, a setting device is included as an integral part of the pump's front cover. The benefit of all these features is the service time. TORNADO® T2 service has been reduced to significantly less than half the time required for servicing a conventional rotary lobe pump. The preset cartridge mechanical seals are fitted directly into the rotor and mounted on the shafts as one assembly. Various cartridge mechanical seals are available that all fit into a common housing allowing for seal upgrades without modification.
