NETZSCH NEMO BY NM038BY Progressive Cavity Pump
Overview
The NETZSCH NEMO BY NM038BY is a compact block-design progressive cavity pump from the world’s leading manufacturer of progressing cavity pump technology. Built around the classic NEMO rotor-stator principle, the NM038BY conveys media ranging from thin, low-viscosity liquids to thick, pasty, or abrasive substances, with or without suspended solids, at a continuous flow rate of up to approximately 18 m³/h and discharge pressures up to 24 bar. Its flanged-drive block construction keeps the footprint compact and the installation economical, while four interchangeable rotor/stator geometries let engineers precisely match the pump to a specific viscosity, solids content, and pressure requirement without redesigning the installation.
Working closely with plant engineers in the region, Seven Star LLC proudly supplies genuine NEMO BY progressive cavity pumps to water treatment operators, industrial process engineers, and EPC contractors across Oman and the wider GCC. Customers in Muscat, Sohar, and Salalah benefit from local technical support for pump sizing and rotor/stator material selection.
Operating Principle
The NM038BY is a positive displacement pump built around a single-thread helical rotor turning inside a double-thread elastomeric stator. As the rotor rotates, sealed cavities form between the rotor and stator and travel continuously from suction to discharge, moving the pumped medium at a rate directly proportional to shaft speed and largely independent of downstream pressure fluctuations. Because the cavity geometry does not compress the fluid, the pump conveys with very low pulsation and minimal shear, protecting fragile or shear-sensitive media while still handling highly abrasive slurries when the appropriate wear-resistant rotor and stator materials are specified.
This mechanism has practical benefits that matter on real plants: the NM038BY is self-priming with strong suction lift, tolerates entrained gas and fluctuating fill levels without losing prime, and can be reversed to empty lines or clear blockages. Because flow rate and pressure capability are set entirely by the rotor/stator pairing, an installed pump can be re-rated for a different duty simply by exchanging these two wear parts, without replacing the pump casing, bearing frame, or drive — a major advantage when process conditions change over the plant’s service life.
Engineering Design of the NETZSCH NEMO BY NM038BY
The NM038BY uses NETZSCH’s block design, in which the drive motor is flanged directly onto the pump body rather than mounted on a separate bearing frame, giving a shorter overall footprint and a lower parts count than bearing-housing designs. The pump housing, joint, and shaft seal are selected to match the process medium, with mechanical seal, packed gland, or magnetically coupled sealless options available depending on the hazard classification of the fluid being handled. Standard connections comply with relevant national and international flange and thread standards, simplifying integration into existing pipework.
Maintenance access is a defining feature of the range: the rotor and stator, the components most exposed to wear, can be removed and replaced without disturbing the pump’s pipe connections in most configurations, minimizing downtime during routine service. NETZSCH’s HD-Stator technology extends stator service life in demanding duties, and the wide selection of stator elastomers and rotor coatings allows the same base pump platform to be configured for wastewater sludge, process chemicals, or food-grade applications simply by changing wetted materials.
Key Features
The NETZSCH NEMO BY NM038BY delivers the reliability NETZSCH progressive cavity pumps are known for in a compact, cost-effective block format, and the NETZSCH NEMO BY NM038BY is engineered for continuous industrial duty:
- Continuous, low-pulsation, pressure-stable conveying of media from low-viscosity liquids to thick, abrasive, or solids-laden substances.
- Flow rate up to approximately 18 m³/h and discharge pressure up to 24 bar at rated speed, suitable for demanding transfer and dosing duties.
- Four available rotor/stator geometries allow precise matching of the pump to viscosity, solids content, and required pressure.
- Self-priming operation with strong suction lift, tolerant of fluctuating fill levels and entrained gas.
- Compact flanged-drive block design reduces footprint and installation cost compared to bearing-housing pump configurations.
- Rotor and stator wear parts are field-replaceable, minimizing downtime during routine maintenance.
- Wide range of wetted materials and elastomer options supports abrasive, corrosive, and hygienic media alike.
- Reversible rotation direction enables line clearing, tank emptying, and precise metering in either flow direction.
- The NETZSCH NEMO BY NM038BY is backed by genuine spare rotors and stators for fast turnaround on routine wear-part replacement.
Industrial Applications
The NETZSCH NEMO BY NM038BY is widely deployed, and the NETZSCH NEMO BY NM038BY is widely deployed in municipal and industrial wastewater treatment for sludge transfer, thickening, and polymer dosing duties, where its low-pulsation, solids-tolerant conveying protects downstream equipment and maintains dosing accuracy even as sludge consistency varies. Beyond water treatment, the same platform serves chemical processing, mining slurry transfer, and general industrial fluid handling wherever a positive displacement pump must move a difficult or abrasive medium reliably over long service intervals.

NETZSCH pump families listed here
The manufacturer groups its pumps under three main names, and one of each is listed. NEMO is the progressing cavity line, here the NEMO BY in block construction, model NM038BY. TORNADO is the rotary lobe line, with the TORNADO T2. NOTOS is the multi screw line, represented by the NOTOS 3NS three screw pump for lubricating liquids. People searching for a NETZSCH screw pump may mean either NEMO or NOTOS, so the nameplate matters. These pumps are found in wastewater, food, chemical and oil and gas service, all present in the GCC.Ordering NETZSCH pumps and parts: what we need
