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.

As the official authorized partner and exclusive regional representative for NETZSCH, 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 not only from authentic NETZSCH hardware backed by full manufacturer warranty, but also from local technical support for pump sizing, rotor/stator material selection, and commissioning — assurance that unauthorized resellers cannot provide.

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.

As the officially authorized partner for NETZSCH, Seven Star LLC distributes the NETZSCH NEMO BY NM038BY and the wider NEMO BY range to municipal utilities, desalination plants, and industrial facilities throughout Oman and the GCC, including wastewater infrastructure projects in Sohar’s industrial zone and process plants in Salalah’s free zone. Regional plant operators value the pump’s proven reliability under continuous-duty conditions and the availability of genuine spare rotors and stators through Seven Star LLC’s local stock, reducing the lead time associated with importing parts directly from Europe.
