Introduction
In industries requiring efficient transfer of solids, sludge, slurry, or powders, GN Separation’s GN Solids Vacuum Pump (also called sludge vacuum pump) stands out as a compact, robust, and versatile solution. Fully powered by compressed air, it offers an efficient and reliable method for material transfer without the need for electricity, making it ideal for a variety of challenging applications, including hazardous and explosion-proof environments.
What is GN Solids Vacuum Pump?
The GN Solids Vacuum Pump is a vacuum-loading solids transfer pump powered entirely by compressed air. It works by creating a high vacuum of 25″hg (85Kpa) to suction materials and uses positive pressure to discharge them. This pump can transfer materials over 500 meters, making it an ideal solution for long-distance operations.
Available in three models—GNSP-10B, GNSP-20B, and GNSP-40B—the GN Solids Vacuum Pump can handle flow rates ranging from 10 m³/h to 40 m³/h. GN can also design Group Pump Units on a single skid for higher flowrate requirements.
Key Features of GN Solids Vacuum Pump
- Fully Air-Powered
- Requires no electricity—powered solely by compressed air.
- Safe for explosive or hazardous environments such as oil, gas, and coal industries.
- High Performance and Versatility
- Handles solids content up to 80% and maximum solid sizes of up to 75mm.
- Capable of transferring materials over distances of up to 1000 meters (GNSP-40B).
- Suitable for sludge, slurry, powder, and other challenging materials.
- Compact and Robust Design
- Portable, lightweight models are available for easy transportation and operation.
- Durable construction ensures reliable performance in tough industrial environments.
- Automatic and Manual Operation
- Large pumps like GNSP-40B can operate in manual or automatic mode.
- Smaller pumps, including GNSP-10B and GNSP-20B, operate automatically.

- Bulk powder (sand, cement, bentonite) transfer
From industrial clean-ups to bulk material handling, GN Solids Vacuum Pumps are trusted solutions for high-volume and challenging material transfer.
Working Principle of GN Solids Vacuum Pump
The pump operates in a two-phase cycle using compressed air:
- Vacuum Phase:
Compressed air creates a high vacuum inside the pump tank, which suctions material into the tank through the suction line. - Discharge Phase:
The valve switches to introduce positive air pressure, pushing the material out through the discharge line.
This simple yet highly effective mechanism ensures continuous and reliable operation.
