Dragflow Dredges & Pumps
Engineered for abrasive loads, remote sites, and tough NZ conditions.
Built for NZ Conditions
Underwater extraction and harvesting processes are inherently complex, with New Zealand’s unique geography adding to these challenges. Dragflow dredges and pumps are specifically engineered to operate reliably in demanding conditions, providing efficient, safe, and cost-effective extraction of material, sludge, and slurry. Whether managing sediment in quarries or other extractive environments, Dragflow offers proven solutions designed to meet rigorous operational requirements.
Smarter Dredging for NZ Locations
Dragflow dredges pump directly from the point of extraction, requiring less energy. Their modular pontoons are remote-controlled or autonomous, offering practical solutions to dredging challenges.
- Local operators have quantified energy cost savings of over 90% versus traditional extraction.
- Pumping from the extraction site eliminates suction lift limitations – reducing energy consumption.
- Remote operation improves safety and reduces downtime.
- Fewer machines = fewer quarry movements and reduced labour costs.
Solutions for Every Site
From digger-mounted pumps to autonomous dredges, Dragflow offers modular, scalable systems for NZ’s quarries, mines, and waterways.
- Submersible dredge pumps with optional jetting rings and side cutters.
- Mini dredges for tight locations or small waterways.
- Remote-controlled DRP dredges for improved safety.
- DRH cable dredges for deep operations.
- Harvesters for pond and channel cleaning.
