Rugged, Pneumatic Transfer Solution for Sludge and High-Solids Waste

GN Solids Control has recently delivered a batch of solids vacuum pumps to an oilfield service company in Africa, further strengthening its presence in the region’s energy sector. These pumps, also referred to as sludge vacuum pumps or solids transfer pumps, are well-suited for tough field conditions where high-viscosity, high-density, or abrasive materials need to be transferred safely and efficiently.

Powered by compressed air, GN solids vacuum pumps feature a fully pneumatic design, eliminating the need for electricity and making them ideal for remote sites or hazardous zones. With no rotating parts in contact with the material, the pump structure is simple, durable, and requires very low maintenance.

Designed for Versatility and Performance

GN vacuum pumps can handle materials with up to 80% solids content, including drilling cuttings, oil sludge, tank bottom residue, sand, and other heavy slurries. Thanks to their high vacuum loading capacity, these pumps offer strong suction power and long-distance discharge capabilities, making them extremely effective in a wide range of industries such as:

• Oil & gas drilling waste management

• Mining tailings and slurry transfer

• Industrial tank cleaning

• Environmental cleanup and remediation

The pumps shipped to Africa will be deployed in challenging onshore oilfield operations, where reliable and low-maintenance equipment is critical to project efficiency. This delivery reflects GN’s ongoing commitment to supporting international customers with robust, application-driven solids handling solutions.
