GN Solids Control’s GNSB series centrifugal sand pumps have become a trusted workhorse across the South American market, serving oil & gas drilling, tunneling, piling, and environmental slurry projects from Argentina to Bolivia and beyond.
South American ProjectsSouth American job sites are demanding—remote locations, abrasive drilling mud, high solids content, and mixed voltage standards (50Hz/60Hz). GN sand pumps are built exactly for these conditions:
• Wear-resistant build: casing and impeller made from hard ductile iron alloy, with tungsten carbide mechanical seals for long service life in sandy, corrosive mud.
• Interchangeable spare parts: 100% compatible with major international brands cutting inventory cost for local service teams.
• Open impeller design: lowers axial thrust, extends bearing life, and handles high-viscosity slurry without clogging.
• Flexible models: flow from 35–320 m³/h, power from 7.5–75 kW, 50Hz/60Hz motor options.
• Drilling mud systems: feeding desanders, desilters, and mud cleaners; transfer pump between tanks; charging pump for rig mud pumps.
• Argentina mud recycling: GN 500GPM systems shipped to Argentina use GNSB5×4J sand pumps to drive the GNZY705E mud cleaner, keeping bentonite slurry clean for TBM and piling work.
• Bolivia drilling rigs: sand pumps paired with GNLW452D centrifuges and shale shakers for two rigs, handling abrasive cuttings-laden fluid.
• Wastewater & sandy slurry transfer: GN centrifugal sand pumps also move wastewater with sand/silt for mining and environmental clients.
For South American contractors, the pump is not just a component—it is the circulation heart of the solids control loop. GN sand pumps reduce downtime, simplify maintenance, and keep cones and centrifuges fed at stable pressure. Combined with GN mud cleaners, centrifuges, and screw pumps, they form a complete closed-loop mud system that cuts fluid loss and disposal cost.
With repeated orders from Argentina, Bolivia, and regional oilfield service companies, GN sand pumps are no longer “trial equipment”—they are standard-spec choices. Backed by GN’s API/ISO/ATEX certifications and Americas-side support, the GNSB platform continues to expand across the continent.
From the Andes to the Pampas, GN sand pumps keep the mud moving—reliably, efficiently, and cost-effectively.
