The "MAP Dredging System" may look like a commonly used Sand Pump. But it is NOT. Its "Smaller Engine Efficiency" provides more dredging volumes with less fuel consumption. You can dredge FASTER, CHEAPER, DEEPER and MORE VOLUMES. This dredging system improves your PRODUCTIVITY AGAINST TIME & COST. Check out the slides and learn all the advantages you can take.

with other commonly used Sand Pumps or/and
Vacuum Suction Pumps. Although the MAP
system is designed as a dredging pump, its
features and performances are different.
