Optimizing Slurry Supply: The Versatility and Efficiency of GN Screw Pumps for Centrifuges

The screw pump stands out as the optimal apparatus for supplying slurry to centrifuges due to its unique features in a waste fluid treatment system. It avoids shearing or mixing the slurry, maintaining a low internal flow rate along the shaft, and ensuring consistent capacity, and stable pressure without causing vortices or stirring. Its composition revolves around two distinctive geometric components: the screw shaft (rotor) and the screw sleeve (stator). These elements work in tandem, generating extrusion that guides the slurry along the shaft.

GN Solids Control is a leading screw pump supplier that our screw pumps boast enhanced durability and reliability compared to most Chinese-made counterparts Crafted with components from leading German brands and assembled in China. Through strategic agreements with NETZSCH, we can provide these pumps at a more cost-effective price than the official site.

Among the favored models is the GNG30B-075C, catering to the GNLW363D centrifuge, boasting a flow rate of 30.3/h, a 7.5kW motor, and DN100 inlet and outlet specifications.

When opting for a screw pump, selecting the right model is crucial for optimal performance. To tailor the choice to the specific physical and chemical characteristics of the media and operational requirements, we encourage users to submit pump operation data. Our team of professionals can then recommend a suitable selection, which is subject to customer confirmation.

The model selection process requires essential operational data:

Transport Medium: Name, corrosiveness, abrasiveness, viscosity, solid content, working temperature.

Operating Parameters: Flow rate or range, maximum pressure, continuous or intermittent operation.

Installation Environment: Horizontal or vertical orientation, fixed or mobile setup, special requirements for connecting pipelines, electrical systems, and explosion-proof protection.

As a progressing cavity pump, the screw pump consists of a helical rotor and stator. The rotor, featuring a large pitch, depth, and a specific cross-section, works in conjunction with a stator with a two or three-start thread, allowing continuous movement of the medium from the inlet to the outlet.

When in need of a centrifuge and feed pump, we recommend choosing the screw pump as your feeding pump. For further information, kindly reach out via email to samuel@gnsolidscontrol.co.

Comparation of GN Screw Press and Centrifuge in Dewatering.

In the field of solids control and waste management, particularly in industries like waste water treatment, the demand for effective dewatering solutions is crucial. Among the technologies that stand out in this domain are the GN Screw Press and the Decanter Centrifuge. Both play pivotal roles in separating liquids from solids, each employing distinct mechanisms tailored to different needs. Let’s delve into a comprehensive comparison of these two technologies to understand their strengths and applications.

GN’s Screw Press  stands as an effective dewatering solution crafted to clarify liquids across various industries. This innovative technology leverages screw extrusion, employing the robust squeezing force generated by the alteration of screw diameter and pitch, along with the minute gap between the floating ring and the fixed ring. 

A primary advantage of the GN Screw Press lies in its low energy consumption. Operating at a lower speed, typically around 2-5 RPM, it consumes less power compared to traditional centrifuges. This not only leads to cost savings but also positions it as a more environmentally friendly option. However, it’s important to note that its primary application is in water treatment projects, and its capacity is relatively less than a centrifuge of similar size.

GN Decanter Centrifuges , on the other hand, are longstanding and widely adopted technologies for dewatering applications. Operating on the principle of centrifugal force, the high-speed rotation of the drum or bowl effectively separates liquids and solids based on their densities.


Decanter Centrifuges are recognized for their rapid dewatering capabilities, ideal for applications where time is a critical factor. GN offers dewatering centrifuge models such as 224, 364, and 554, with a length-to-diameter (L/D) ratio of 1/4. In industries like oil drilling, where swift clarification of drilling fluids is essential, centrifuges excel in delivering rapid results with a L/D ratio of 1/3. Additionally, decanter centrifuges prove proficient in separating oil-based fluids.

However, the efficiency of centrifuges comes at a cost, both in terms of energy consumption and maintenance requirements. These machines typically have a higher energy consumption rate, requiring substantial motor power. Furthermore, the high-speed rotation can lead to increased wear and tear, necessitating higher maintenance for the bowl and conveyor components. And the recommended feed pump is GN screw pumps for low speed, and steady pressure supplying.

When deciding between the GN Screw Press and a Centrifuge, several factors should be considered. These include the nature of the material being processed (solids particles, density, etc.), the required level of dewatering, energy efficiency goals, and maintenance considerations.


It’s worth noting that if equipment needs to be placed outdoors, protective measures, such as sun and rain shields, are advisable for the Screw Press, whereas the Decanter Centrifuge can be exposed directly to the elements.

Recently, GN Solids Control, a leading manufacturer of solids control equipment and mining vibrating screens in China, made a significant impact at the 2023 Indonesia Exhibition for Mining and Oil. The visitors around the world came to learn about GN equipment at our stand.

The range of products, including shale shakers, decanter centrifuges, and HDD & CBM equipment packages, has found widespread adoption among Indonesian and other clients around the world. The shale shaker is the first step in solids separation equipment for coarse particles. and the centrifuge used to separate fine particles around 2-5 um. Besides, for the HDD and CBM equipment packages, we also introduce our mud system including skidded equipment and vacuum pump, which need the air supply but have very strong suction ability, for high solids materials.


2023.09.18 Indonesia Exhibtion

Besides, a great part of the equipment at the exhibition was our collaboration with GN Separation, including mining screens and screen panels. GN equipment was first welcomed in the oil and gas industry, and now also share a commitment to advancing the field of environmental waste treatment and mining industry. The GN booth attracted many local professors and managers, who were eager to engage in discussions about the latest industry projects and share our knowledge.
