Powerful Transfer of Sludge and Drilling Waste in Harsh Environments

GN Solids Control has recently completed the shipment of a batch of solids vacuum pumps to a major oilfield service company in Africa. These pumps are purpose-built to handle the challenges of transferring thick sludge, viscous fluids, oily waste, and high-solids content slurry commonly found in oil & gas and industrial operations.

Also known as sludge vacuum pumps, GN’s units are fully pneumatic-operated, enabling use in hazardous and remote locations without relying on electric power. This makes them especially suitable for field conditions where safety, reliability, and mobility are essential.

High Solids Handling Capacity, Minimal Maintenance

The vacuum pump design is based on a high vacuum suction and pressure discharge cycle, capable of moving materials with a solids content up to 80%. It can transfer dry, wet, and even abrasive materials over long distances without clogging. Since there are no internal rotating parts in contact with the fluid, the pump offers high durability and reduced maintenance, even in the most demanding environments.

Applications include:

• Drilling waste transfer

• Oil sludge recovery

• Tank cleaning

• Mining slurry handling

• Environmental clean-up projects

This successful delivery to Africa is a testament to GN’s ability to provide practical, efficient, and field-proven pumping solutions tailored to global clients’ needs.

GN Solids Control continues to support oilfield service providers with modular, low-maintenance equipment designed to improve operational efficiency and environmental compliance.
