Dragflow, an Italian manufacturer of heavy duty pumps and complete dredging equipment, recently installed their hydraulic pump HY85HC and 2 hydraulic excavators EXHY20 at a quarry pond in Japan.
According to Dragflow, a Japanese quarry company was in trouble – as a result of the stone and sand wash process, their collection pond was almost full of dense mud.
“Their productive capacity was at risk: they urgently needed to restore the pond’s capacity,” said Ms Doris Zaccaria, Dragflow’s marketing manager. “When the installation was over, the Japanese company breathed a sigh of relief: the pump was efficiently removing the dense mud accumulated in the pond.”
Dragflow heavy-duty pumps have been designed and built to work especially in burdensome conditions, the company said.
These pumps can be equipped with cutters, which coupled with the agitator stir up the solids settled on the bottom in order to be easily pumped out and creating a homogeneous mixture with higher percentage of solids, getting a higher efficiency.
