Exploring the Capabilities of GN Solids Vacuum Pump: Revolutionizing Industrial Waste Management

At GN SEPARATION, we take pride in our new solutions for industrial waste management. One of our flagship products, the GN Solids Vacuum Pump, also known as the sludge vacuum pump, is an innovation in the field of solids transfer. This vacuum loading solids transfer pump is fully powered by compressed air, making it an efficient and reliable solution for transferring solids, powder, slurry, and sludge.

What Makes GN Solids Vacuum Pump Stand Out?

The GN Solids Vacuum Pump is designed to be compact, robust, and incredibly efficient. It utilizes a powerful vacuum of 25″ hg to load materials and is capable of delivering them over distances of up to 500 meters. Available in three different capacities (10 m3/h, 20 m3/h, and 40 m3/h), these pumps can also be customized as Group Pump Units on a single skid, offering versatile and scalable solutions for various industrial needs.

Key Applications

The versatility of the GN Solids Vacuum Pump makes it suitable for a wide range of applications, including:

  • Thickener De-sludge: Efficiently removes sludge from thickeners.
  • Tunneling & TBM Applications: Ideal for tunnel boring machines and excavation projects.
  • Sump and Shaft Cleaning: Cleans sumps and shafts effectively.
  • Tailings and Ash Pond Cleaning: Handles the cleaning of tailings and ash ponds in power stations.
  • Oil Spill Capture and Transfer: Captures and transfers oil spills efficiently.
  • Hazardous Waste Recovery: Safely recovers and transfers hazardous waste.
  • Drilling Mud and Cuttings Transfer: Transfers drilling mud and cuttings in oil and gas operations.
  • Mining Slurries and Offal Transfer: Moves mining slurries and waste materials.
  • Bulk Transfer: Handles bulk transfer operations, both loading and unloading.

Working Principle of the GN Solids Vacuum Pump

The GN Solids Vacuum Pump operates on a simple yet powerful principle. Compressed air is fed into the pump, creating a high vacuum inside the pump tank. This vacuum draws materials into the tank through the suction line. After a few seconds, the valve changes the air direction to create positive pressure, pushing the material out of the pump tank through the discharge line.

The GNSP-40A, a larger model, offers both manual and automatic modes, while the smaller models, GNSP-10A and GNSP-20A, operate automatically. This pneumatic operation ensures safety and reliability, especially in hazardous environments like the oil, gas, and coal industries, where explosion-proof equipment is essential.

GN Vacuum Cleaner for Industrial Waste

In addition to the GN Solids Vacuum Pump, we offer the GN Mini Vacuum Cleaner, designed for tough industrial clean-up jobs. This mobile and lightweight suction tool is air-operated, producing a high vacuum for efficient suction and can switch to positive pressure for discharge. Operators can set up automatic suction and discharge cycles, enhancing efficiency and ease of use.


The GN Solids Vacuum Pump and GN Mini Vacuum Cleaner are at the forefront of industrial waste management technology. Their robust design, efficient operation, and versatility make them invaluable tools for a wide range of applications. At GN SEPARATION, we are committed to providing innovative solutions that meet the evolving needs of our clients.
