The pump for sand (the deep pump Dragflow)
The Dragflow company the producer of submersible centrifugal pumps for extraction of sand, dredging works, transfer of a pulp.
The pumps "Dragflow" allow:
- To perform works at depths up to 35 m;
- To work with productivity up to 350 m3/hour on dry material (1200 m3/hour on a pulp), with transportation of a pulp more than 1 kilometer.
- To use the electric and hydraulic drive;
- To pump over the accumulating slimes thanks to a hydraulic washing-out or rykhlitelny excavators with the maintenance of firm particles to 50% on volume and 70% on weight;
- To pump over a pulp with a density up to 2.2 kg/dm3;
- To pump over high-abrasive mixes with the changing density percent;
- To resist to wear of flowing part of the pump thanks to the low speed of rotation and use of material with a hardness up to 650 units according to Brinell
