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.
Efficiency, Safety, and Cost Control
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.
Fit-for-Purpose Equipment
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.

Frequently asked questions
Selecting the right dredging equipment is critical for maintaining efficiency, safety, and cost control in demanding environments. Dragflow dredges and dredge pumps are engineered to provide reliable performance where traditional systems may struggle, from handling abrasive materials to operating with fewer personnel and reduced downtime. The FAQs below address key questions about how Dragflow technology supports consistent, high-quality results in New Zealand’s extractives sector.
What makes Dragflow pumps more efficient than traditional dredging systems?
Submersible design eliminates suction lift limits, reducing energy use and improving throughput.
Can Dragflow equipment handle abrasive materials?
Yes. Pumps are designed for high solids concentrations (up to 70% by weight) and abrasive loads.
Are remote operation available?
Absolutely. DRP series dredges offer remote and autonomous control for safer, more efficient dredging.
