Over time, the sand from the shore is carried into the water. Rains, waves, feet of beachgoers. Therefore, it becomes necessary to return the sand to the shore.
Sand can be brought from another quarry by dump truck. But sometimes it’s easier to get sand from the bottom.
The Piranha mini dredger can help us with this.
But if you are not engaged in large volumes of work, then you can use other motor pumps for dirty water. These can be motor pumps for dirty water from well-known companies.

Wacker Neuson, Honda, Koshin, Daishin, Robin-Subaru, Tsurumi

When using domestic dirty water pumps for pumping abrasive mixtures, the manufacturer’s warranty period is reduced. This must be remembered in order not to make claims to the manufacturer of motor pumps. But their use for pumping sand is justified, because the cost of a motor pump is paid off by the cost of the pumped dry residue.

For efficient operation, two motor pumps are required. One for dirty water, and the second motor pump is a high-pressure clean water motor pump for hydraulic washing.

suction head for mini dredge

For the operation of a mini dredger, we recommend the Bagermaster suction nozzle, which increases work efficiency by 10-20% in the presence of algae and debris in the water.
