The demanding environments of African oilfields require robust, reliable, and efficient equipment, especially for handling challenging materials like drilling mud, sludge, and solids-laden waste. We are pleased to announce the supply of a batch of specialized Sludge Vacuum Pumps (also known as Solids Transfer Pumps) specifically designed to meet these rigorous needs.

What is a Sludge Vacuum Pump?

This advanced pneumatic vacuum pump is engineered for the tough job of transferring liquids, slurries, and – critically – dry solids. It stands out as a High Vacuum Loading Solids Transfer Pump, making it uniquely suited for harsh oilfield conditions where performance and minimal downtime are paramount.

Key Advantages for African Oilfield Operations:

High Vacuum Performance: Excels at loading and transferring difficult materials, including sticky sludge and dry solids.

Exceptional Solids Handling: Capable of transferring materials with high specific gravity and high density. Crucially, it handles slurries with solids content up to an impressive 80%.

Rugged & Reliable: Built to perform consistently in tough environments, minimizing operational disruptions.

Low Maintenance: Designed for simplicity and durability, reducing service requirements and operational costs – a vital factor in remote locations.

Versatile Transfer: Efficiently moves liquids, viscous slurries, and dry bulk solids using the power of vacuum.

Why This Pump is Ideal for Oilfield Sludge & Solids:

Traditional pumps often struggle with the abrasive, dense, and highly solid-laden materials common in oilfield waste streams (like tank bottoms, pit cleaning, and drill cuttings). The GNSP series Solids Vacuum Pump overcomes these challenges:

Handles High Solids Content: The ability to pump slurries with up to 80% solids content is a game-changer for efficient waste transfer and tank cleaning.

Dry Solids Capability: Easily transfers dry bulk materials like bentonite, barite, or dried drill cuttings.

Vacuum Loading: Simplifies the process of picking up material directly from sumps, tanks, or pits without complex priming systems.

Pneumatic Operation: Safe for use in potentially hazardous environments (no electric motors sparking) and requires only compressed air.

Reduced Clogging: Designed to minimize blockages when handling challenging solids mixtures.

This supply of GNSP series Solids Vacuum Pumps provides our African oilfield service client with a powerful, reliable, and low-maintenance solution for their critical sludge and solids transfer operations. By choosing this high-vacuum technology, they are equipping their teams to handle the toughest materials efficiently, ensuring smoother operations, reduced downtime, and lower maintenance burdens in the challenging African oilfield environment.

We are proud to announce the successful customization and delivery of Two Sets GN Container-Type Cuttings Dryer Systems for an overseas client, designed to optimize drilling waste management and enhance environmental compliance. This integrated system combines advanced technology, robust performance, and modular portability, making it ideal for oil and gas drilling operations. Below, we break down the key components and features of this cutting-edge solution.

1. GNCD930G-GP Vertical Cuttings Dryer
At the core of the system lies the GNCD930G-GP, a single-stage, continuous-operation horizontal scraper discharge centrifuge from the GNCD Series. This vertical cuttings dryer is engineered to efficiently recover oil-based components from drilling cuttings, reducing the Oil-on-Cuttings (OOC) content to below 5% post-treatment.

Processing Capacity: 30–50 tons per hour (up to 50 tons/hr for GNCD930G-GP).

Versatility: Compatible with oil-based mud (OBM), synthetic-based mud (SBM), and composite-based mud.

Adaptability: Performance correlates with mud viscosity, which is influenced by factors such as solid content, particle size, drilling fluid type, and temperature.

Safety Certifications: Offers multiple explosion-proof certifications, including ExdIIBt4, IECEx, and ATEX, ensuring safe operation in hazardous environments.

This dryer works seamlessly alongside other solids control equipment (e.g., shale shakers, decanter centrifuges, hydrocyclones) to deliver a comprehensive waste management solution.

2. Liquid Storage Tank (1.5m x 2m x 1.2m)
The system includes a durable 1.5m x 2m x 1.2m liquid storage tank for temporary containment of recovered drilling fluids. This tank ensures efficient fluid recycling and minimizes waste, supporting sustainable operations.

3. Progressive Cavity Pump
A high-performance screw pump (progressive cavity pump) is integrated into the system to ensure smooth transfer of drilling mud and cuttings. Its wear-resistant design guarantees reliability in handling viscous or abrasive fluids.

4. Containerized Design
The entire system is housed within a standardized shipping container, enabling easy transportation, rapid deplo  yment, and minimal on-site installation. This modular design is ideal for remote or offshore drilling sites.

5. Screw Conveyor
An automated spiral conveyor efficiently transports dried cuttings to designated disposal or storage areas, reducing manual handling and streamlining workflows.

Why Choose the GN Container-Type Cuttings Dryer System?

Eco-Friendly: Reduces OOC to <5%, meeting stringent environmental regulations.

High Efficiency: Processes up to 50 tons/hr, minimizing downtime.
