Dredge Pumps


Our HydraMaster dredge pump line covers a complete range of sizes from 8-inch to 28-inch discharge and can be used for conventional or underwater service.

The HydraMaster pump offers a combination of high performance, rugged construction and a straightforward, simple design. Combine these factors with proper care and routine maintenance and the HydraMaster will provide many years of dependable, productive service.

HydraMaster wear parts are available in high Brinell Duralite which offers superb resistance to severe abrasion and moderate impact, or Permalloy which exhibits high strength and ductility when subjected to impact loading with extremely good wear at an intermediate hardness level.

  • Single, sealed bearing cartridge with heavy duty, anti-friction, self aligning spherical roller bearings.
  • Heavy duty, one-piece pump shell that can be mounted for variable discharge angles through 360°.
  • Interchangeable front and rear liners reduce your spare parts inventory.
