GN Separation has recently completed the assembly and final packaging of a batch of Vacuum Pumps. These fully pneumatic units, engineered for high-efficiency conveying, are now en route to a key client in the Middle East. They will be deployed to handle oily sludge, one of the most challenging byproducts of oil and gas operations.

A Pneumatic Powerhouse: How the GN Solids Vacuum Pump Works

At the core of this technology lies a 100% air-driven pump designed to transport a wide range of materials safely and reliably. Unlike conventional mechanical pumps with rotating parts prone to abrasion and frequent maintenance, GN’s Vacuum Pump operates entirely on compressed air. This eliminates the need for electricity, significantly reducing maintenance costs and improving safety in hazardous environments.

The pump operates on a cyclical “suction–discharge” process. During suction, compressed air creates a strong vacuum that draws in materials such as liquids, slurries, powders, or aggregates. Once the chamber is filled, the airflow reverses, discharging the collected material through an outlet pipe. This simple yet robust design ensures consistent performance, even with highly viscous or abrasive media.

Versatile Applications Across Industries

The GN Solids Vacuum Pump has proven its value in diverse industries, offering efficiency and safety in applications where traditional pumps often fail:

Environmental Protection – Sludge Pool Cleanup
In wastewater and effluent treatment, sedimentation tanks often accumulate heavy, viscous sludge. GN Separation’s vacuum pump streamlines removal, transferring sludge directly to dewatering units or disposal sites while reducing manual labor and safety risks.

Mining – Reliable Slurry Transfer
Mining slurries containing abrasive minerals pose major challenges for mechanical pumps. The vacuum pump’s clog-resistant design and strong suction capacity make it ideal for moving high-solid-content mixtures over distance with minimal downtime.

Oil & Gas – Oily Sludge Management
For the Middle Eastern project, the pump will be used to extract oily sludge from pits and separators. The pneumatic design is intrinsically safe, preventing ignition risks in explosive environments while ensuring compliance with international safety standards.

Sustainable Engineering with Practical Benefits

By replacing energy-intensive pumping methods with a pneumatic, wear-resistant design, the GN Solids Vacuum Pump reduces reliance on fossil fuels, minimizes waste, and aligns with global sustainability goals. At the same time, clients benefit from lower operating costs, longer service life, and reliable performance under harsh conditions.

GN Separation’s commitment to combining robust engineering with environmental responsibility continues to drive innovation in industrial material handling, delivering practical solutions for the world’s most demanding applications.

News from GN company this week: Recently, 1 series of oil solids Vacuum Pumps have been manufactured as stock and ready to meet the spot sales and we can start shipping the pumps to support clients’ urgent projects.

To make sure the vacuum pumps will provide a reliable performance and every parts and components of all the equipment will run smoothly for a long term operation, our technical department, production department and quality control department have paid a lot of attention to the material selection, material preparation, every step of production and the inspection in each step.

If you need any support about the operation and maintenance of Vacuum Pump, please feel free to contact GN company for our engineers’ best experience and knowledge in the relevant industry. We will do our best to assist your project because just in this way we can establish a stable and long term cooperation. And we can provide on-line support and site instruction for specific situation if needed.

As a leading manufacturer of separation equipment and conveying equipment, GN always pay high attention to the product quality and consider the long-term benefits for our users. We would also like to introduce GN as a professional manufacturer in decanter centrifuge field, GN pays a lot of attention in the selection of raw materials, high-quality centrifugal casting or forging stainless steel materials are used, and for wearing parts, hard alloy protection is used.

GN high-end CNC lathes, CNC centers, and CNC gantry milling machines can better ensure the machining accuracy of centrifuge parts. In terms of the dynamic balance of the decanter centrifuge, in addition to the ordinary low and medium speed dynamic balance, GN also applies a high speed dynamic balance process, which can dynamically balance the centrifuge screw and bowl at the actual working speed of the centrifuge. In terms of market applications, GN decanter centrifuges are widely used in the industry, and the products are exported to more than 60 countries and regions in the world, and have won high praise from customers.
