GN Separation is delighted to announce that a batch of GNSP-20B Solids Vacuum Pumps has finished production and is fully prepared for shipment to an international customer. This shipment fully demonstrates GN Separation’s consistent dedication to providing durable, high-performance solids transfer solutions tailored to harsh and complex industrial working conditions.

Featuring a compact structure, rugged build and outstanding operating efficiency, the GNSP-20B Solids Vacuum Pump creates a maximum vacuum of 25 inHg for material suction and is capable of conveying various media over a distance of over 500 meters, depending on material characteristics and on-site system configuration. Adopting a full pneumatic driving design, the pump requires no electric power, enabling safe, stable and flexible operation in a wide range of complex industrial environments, especially in explosion-proof scenarios.
GN Solids Vacuum Pumps are available in three standard models with throughput capacities of 10 m³/h, 20 m³/h and 40 m³/h, allowing customers to choose the most suitable equipment according to their actual transfer throughput demands. For large-scale projects requiring higher processing capacity or centralized material transfer, GN Separation can also customize skid-mounted combined pump units. The integrated system combines multiple vacuum pumps and supporting auxiliary parts into a single compact turnkey unit, saving installation space and simplifying on-site operation and maintenance.
Benefiting from excellent multi-media handling capacity, GN series solids vacuum pumps are applicable to diverse industries and working scenarios. Their typical applications include thickener desilting and desludging, tunneling and TBM construction operations, sump and shaft cleaning, tailings and ash pond remediation, digester and lagoon sludge cleaning, oil spill collection and transfer, as well as conveyor belt bottom spillage cleanup. Additionally, the pumps are widely used for hazardous waste recovery, drilling mud and cuttings transfer, mining slurry and waste residue conveyance, and large-volume sludge and slime treatment.
A prominent advantage of GN Solids Vacuum Pumps is their strong adaptability to difficult-to-handle materials that cannot be effectively conveyed by traditional pumping equipment. Equipped with vacuum suction feeding and compressed air positive pressure discharging technology, the pumps perfectly handle high-solid-content sludge, abrasive slurries, sediment and various accumulated wastes, providing a reliable and efficient solution for complex solids transfer challenges.
The successful completion of this batch of GNSP-20B pumps verifies GN Separation’s mature manufacturing technology and strict full-process quality control system. Every piece of equipment undergoes comprehensive and rigorous pre-shipment inspection to ensure all technical indicators and operational performance fully meet international industry standards and customer requirements.
GN Separation has long been committed to developing practical, efficient solids handling and separation technologies for global customers. With the advantages of compact design, powerful transfer capacity and wide application adaptability, the GNSP-20B Solids Vacuum Pump serves as an ideal solution for various tough solids and sludge transfer tasks.

Moving forward, GN Separation will continue to empower global partners with high-quality vacuum loading and solids transfer equipment, delivering reliable equipment and professional solutions for mining, tunneling, wastewater treatment, oil and gas, environmental remediation and other heavy-duty industrial fields.
