Key Features of a Dredge Pump

The defining features of a high-performance dredge pump include:

High-Chrome Alloy Construction: Critical components like the impeller and volute are cast from wear-resistant materials to withstand constant abrasion.

Large Internal Clearances: The pump's internal passages are widened to allow large rocks and debris—sometimes up to 15 inches in diameter—to pass through without clogging.

Agitator or Cutter Attachments: Many models feature external agitators or jetting rings to break up compacted sediment, turning it into a "pumpable" slurry.

Low Rotational Speed: By operating at lower RPMs compared to water pumps, dredge pumps significantly reduce the rate of internal erosion.
