DREDGE PUMP SELECTION CHART

WN300 Dredge Booster Pump

Note: Approximate Performance For Clear Water, To Be Used For Primary Selection Only.

√ WN300 Dredge Booster Pumps are the heart to the dredgers according to its capacity, working efficiency, transferring distance, suction depth. DOD Dredge Pump is designed with features of resistance to wear and malfunction, and general robust and reliable character, which are highly successful proven in the abrasive sand dredging industry.
√ Dredge Booster Pump offers a complete range of single-or double-walled, inboard or submerged, which are available for different uses. They can be used in the inboard or submerged by single and double-walled types.
√ Dredge Booster Pump has a robust and proven design, which has been successful in many dredgers in all circumstances, which takes the large capacity of fine sand, long-distance pipeline transportation, high suction depth, more working efficiency.
√ The high-efficiency dredge pump has been optimized to upgrade pump production and suction characteristics, and reduce wear, through unique design on the impeller, door, and liners. The higher efficiency to dredge pump, the lower costs to engine power, as well as the improvement to the cost-effectiveness of production and reduction to cost-cycle.
√ Booster is a new type of dredge pump with gearbox by using one base and shaft, by joint-design with “China Advance Gear Box Group”
√ Dredge Pump Spare Parts include impeller, casing, frame plate liner insert and throat bush are all used in material of high chrome alloy for high efficiency in working during the life of sand dredging.
