It has increased mobility, small size, remote control, easy to maintain and safe. The dredger is equipped with a DRAGFLOW EL1204B electric slurry pump with an agitator, with two EXEL20 rippers, a hydraulic loosening system and has a capacity of 400 m3/h for a mixture or up to 120 m3/h for solid components (sand, soil). The depth of the excavation is up to 20 m.

Technical characteristics of the pump:
Head – 37.0 m
Power – 90 kW (120 hp)
Rotation speed – 1450 rpm
The diameter of the pressure pipe is 200 mm.

➔ Main characteristics and advantages of the DRAGFLOW DRP dredger:
- The DRP dredger has a remote control. There is no need to place the dredger operator on the deck of the pontoons. Since the dredger and pump are controlled by the operator from the shore (from a safe distance of up to 100 m), there is no need to ensure its environmental protection. This convenient solution has found its effective application for pumping pulp (sludge) in hard-to-reach and heavily polluted water areas (sludge settling tanks, storage tanks, tailings storage tanks).
- The DRP dredger is equipped with lifting winches and optionally a propulsion system.
- The DRP dredger is equipped with a hydraulic loosening system (pressurized water supply through a hydraulic loosening ring), which ensures more efficient and saturated pumping of pulp in the area of the suction nozzle of the pump.
- Ground pumps are certified: EAC Declaration of Conformity;
- The option of controlling the dredger and pump from shore via a signal cable is available;
- The DRP dredger has a compact and small-sized design, which ensures its high mobility, the ability to quickly transport without dismantling to another place for work or storage.
- Quick installation (dismantling) of the dredger by two workers during the working day;
- Dredger transportation can be carried out on a standard low-bed trailer, scow and other types of transport;
- Powered by 380/50 mains (or mobile generator)
- There is a wide possibility of modification: GPS system, CCTV cameras, navigation lights, hydraulic loosening system (Jet Ring System), EXEL20 rippers, etc.
- A significant advantage of the DRP dredger is its high efficiency, short payback period, and high ROI (Return On Investment) — the return On investment ratio.
