Dredge Booster Pump
- Description



Dredge booster pump is mainly used for long-distance transportation of sand, or construction mud slurry. When one pump cannot reach the discharge distance, connect two or more pumps in series, so as to meet the transportation requirements through pressurization. The products size ranges from 4 inch to 40 inch, and one single booster pump can achieve a maximum delivery distance of 5000 meters.
