Build the selection around your duty
Mixture and solids
Sand/gravel grading, maximum particle, liquid and solids density, and concentration range.
Related resources: Desilting and sediment transfer applications
Dredging system
Suction geometry, dredging depth, discharge elevation, pipeline length and diameter.
Equipment package
Operating speed, driver, base, transmission, sealing utilities, spares and required drawings.
The industrial brochure supplies a family overview, not a model-specific performance table. Its broad flow and head envelopes are not combined into a duty point.
Need a model-specific curve?
Provide the actual slurry and operating point so the proposed model, speed and material can be reviewed together.
Heavy-Duty Dredging Pump construction and operation
The heavy-duty dredging direction is presented in the supplied industrial brochure for sand, gravel and abrasive-mixture transfer. A dredging duty joins the pump to a changing suction source and a discharge pipeline, so the whole transport system needs review.
Describe the mixture flow, solids grading, concentration, dredging depth, suction layout and discharge distance. The brochure gives a broad family overview rather than independently verified model curves. A proposed pump needs an applicable curve, maximum passage, operating speed, pressure limit and arrangement drawing before its driver and installation can be finalized.

Components, materials and seals
Impeller
Review impeller construction and material against the solids, speed and hydraulic duty. Use the selected model parts schedule.
Casing & wear parts
Wear-material schedule to be agreed for the dredged mixture and selected pump.
Shaft sealing
Select the applicable seal around inlet pressure, liquid chemistry and utility availability. Seal options require the selected assembly.
Bearing assembly
Coordinate shaft support, alignment, lubrication and transmission loads. Keep access for inspection and maintenance.

Define the changing suction conditions and the discharge pipeline route through the project.
Sand and gravel movement
Use the complete grading and density range to review passage, wear material and absorbed power.
Sediment handling
Include debris screening, sediment condition, operating cycle and the extraction arrangement.
