This dredge pump adopts heavy-duty horizontal cantilever centrifugal construction. Wetted components including impeller, volute casing and liner are made of high-chromium alloy, Ni-hard or rubber-lined material to resist continuous scouring of sand and gravel particles. Impeller adopts 3-5 pieces of wide-blade design to improve large-particle passing capacity.We provide professional working-condition calculation, factory performance test report, installation-operation manual and complete export-oriented technical documents. OEM service and full-set interchangeable wear spare-parts are available for dredging project requirements.

Product Advantages
Superior Large-particle Passing Performance
Optimized wide-flow-channel 3-5 vane impeller greatly reduces blockage risk, stably transports sand, gravel and mixed sediment with big solid grains.
Heavy-duty Wear-resistant Structure
Key wetted-parts adopt high-chromium alloy or Ni-hard material, resisting strong particle impact and abrasion for long-term dredging continuous operation.
Flexible Multiple-unit Series Operation
Several pumps can be connected in series to satisfy long-distance and high-lift dredging slurry transportation demands.
Various Drive Options
V-belt, direct coupling, gearbox or diesel engine drive optional, adapting shore-based and floating barge installation conditions.
Multiple Shaft Seal Choices
Expeller dynamic seal, packing seal and mechanical seal for different flush-water resource conditions on dredging sites.
Convenient Maintenance & Complete Spare-parts
Back-pull-out structural design for quick disassembly inspection; full-range interchangeable wearing spare-parts support short-lead-time supply to cut field downtime loss.
Product Customization
Wetted-part Material: Custom high-chromium alloy, Ni-hard or rubber-lined components according to particle hardness and medium abrasion degree.
Performance Parameter Adjustment: Adjust impeller dimension, rotating speed and drive mode to match target flow and head; offer multi-pump series scheme design.
Shaft Seal Configuration: Configure expeller seal, packing seal or mechanical seal based on on-site flush-water supply condition.
Drive Form Selection: Select V-belt, gearbox, electric motor or diesel engine drive for barge-mounted or land-based installation.
OEM & Spare-part Service: Accept customer-branded OEM production; supply impeller, liner, throat bush and other replaceable wear parts per drawings or samples.
FAQ
Q: What factors shall be considered when selecting dredge pump for river dredging project?
A: Need to confirm required flow and head, maximum solid particle size, slurry concentration, conveying distance, installation way (barge-mounted or land-based) and flush-water supply condition.
Q: What working-condition data should be offered for quotation of dredge pump?
A: Please provide required flow rate, total head, maximum passing particle size, solid weight concentration, conveying distance, installation form and destination port information.
Q: Can this pump be installed on floating dredge barge for marine dredging work?
A: Yes. We can optimize base and anti-corrosion treatment for barge-mounted installation; diesel engine drive solution is also available for no-power offshore working sites.
