Submersible dredge pump with cutter head is specially designed and engineered for continuous operation in tough, abrasive sand pumping applications. Our DMS Series hard wearing submersible sand pump is made of high chrome iron construction for wet end components such as the casing, agitator, wear liners and impeller which are designed for a long service life in tough applications. Submersible dredge pump with cutter head motor is fabricated with advanced double mechanical seal arrangement that operates in an oil bath away from the pumped fluid, it also has thermal overload and moisture detection float switch for safe operation. The high pressure water gun and the side cutter head system can be added for hard sand layer mixing operation, so the submersible sand pump can handle up to 50% solids per weight. Submersible dredge pump with cutter head features robust construction, steep curves, high efficient, excellent reliability and durability, high chrome wet end parts, longer service life, etc.

Customer got a coastal road construction project. The beach is about 50-100m away from the edge of the proposed coastal road. The open sea is on the right side, they planned to pump sand some 200 meters away and 3m deep to be used as sand fill materials for the proposed road and also to fill up the geotubes (the 2 layer sausage-shaped 5.5m.wide x 25m.long with a volume of 120 cu.m. per 25 meter-segment). They want to fill 1 segment of geotube (120 cu.m. sand) with sand within half an hour. So they are looking for a submersible dredge pump with capacity  600m3/h.

We studied the drawings sent by the customer. In order to improve efficiency, we recommended that  two submersible dredge pumps with cutter head with capacity of 300m3/h can be applied for the project. Because if it is a 600m3/h pump, there is only one sand pumping point. If using two submersible dredge pumps with cutter head, there can be two sand pumping points. This will improve the efficiency of sand pumping and reduce loss rate. When one submersible dredge pump with cutter head stops working, the other submersible dredge pump with cutter head can keep running. Finally we choose the model ZJQ 300-20-37 Submersible dredge pump with cutter head. The cutter head power is 5.5 KW. After nearly 15 working days, all the products are ready.
