01 · Wide rivers
Heavy placer beyond what a 4-inch can handle
19 m³/h capacity and an 8-inch hose suit wide, fast rivers where smaller dredges starve out on flow.

03 — How it works
Four stages from launch to gold capture
Direct-drive powertrain, two-diver dive crew, doubled-length sluice — set up for long shifts on wide rivers.
STAGE 01
Launch & anchor
One 20-foot container delivers the complete unit. The PE hull is launched, anchored, and oriented against current — no separate barge required.
STAGE 02
Engine + pump
40 hp gasoline engine drives the P1500 pump directly. 400 m³/h flow rate produces strong suction across the full 8-inch hose at 12 m depth.
STAGE 03
Two-diver dive
GAST K263 oil-free compressor supplies air to two divers simultaneously. Jet tee with dual nozzles reduces stone-blockage probability.
STAGE 04
Doubled sluice recovery
4.8 m sluice box captures gold across a doubled riffle bed — and recovers diamonds in the same pass for combined-mineral operations.
04 — Why QRUN-GD 8IN
The lightest, quietest, most fuel-efficient class
The four design choices that put QRUN-GD 8IN ahead of competing 8-inch dredges in its weight class.
01 — PROPULSION
Direct-drive, 9 L/h fuel consumption
The 40 hp engine drives the P1500 pump directly — no clutch loss, no belt slip. The engine-pump-compressor combination is the lightest, quietest, and most fuel-efficient gold-dredge powertrain in the 8-inch class today.
02 — SUCTION
Jet tee + dual nozzles
The jet tee design maximises siphon at 12 m depth and reduces the probability of stone blockages on coarse gravel beds.
- P1500 pump · 400 m³/h flow
- Dual injection nozzles
03 — HULL
High-strength PE, weather + corrosion resistant
The floating body is high-strength PE with excellent weather and corrosion resistance — survives salt, sun, and abrasion across multi-season operations.
04 — CREW
2-diver air supply (US-made GAST K263)
Oil-free GAST K263 compressor supplies sufficient air for 2 underwater operators simultaneously. Recover gold and diamonds across the same pass with a doubled-length sluice.
05 — Application scenarios
Where QRUN-GD 8IN is the right call
Four operating profiles for QRUN-GD 8IN — wide-water, deep-water, large-team operations a 4-inch dredge cannot reach.
02 · Lakes & lagoons
Stable PE hull holds station across long shifts
Corrosion-resistant PE floating body suits brackish lagoons and lakes; doubled sluice keeps recovery flat at sustained feed.
03 · Deep-dive crews
Two-diver air supply down to 12 m
GAST K263 compressor supports coordinated two-diver shifts on bedrock-grade gravel beds.
04 · Gold + diamond combo
Doubled sluice captures both in one pass
4.8 m sluice doubles the riffle bed — combined gold + diamond recovery without a second processing line.
