Dredge pumps

Double-walled and single-walled dredge pumps

Single-walled pumps - a compact, economic and robust design with a long effective operating life and easy maintenance.

Double-walled pumps - fitted with an external pump housing which allows the internal pump housing to be made in extra wear-resistant material. This means a smaller part of the wall thickness is needed for mechanical strength and a larger part is available for wear losses. The outer housing also offers optimal security. In case of fracture of the internal pump housing the outer housing prevents flooding of the pump room.

Conventional pumps

The IHC conventional pumps are those which made IHC pumps famous and are still popular because of their combination of large sphere passage, suction properties and price.

High efficiency pumps

High efficiency pumps are those that receive extra design refinement to reduce flow resistance. They are currently the norm for newbuilding projects and are well known for their high efficiency, wear resistance and compactness.

Cutter special pumps

Cutter special pumps are specifically designed to combine a large sphere passage with good suction properties and maintaining a high efficiency.

Important characteristics of IHC dredge pumps
- long working life in abrasive conditions
- wear-susceptible parts available in abrasion-resistant materials
- wear susceptible parts can be simply replaced
- wide sphere passage between vanes to minimise blockages
- easy disassembly for inspection and repair
- limited influence of wear on pump performance
- low net positive suction head requirement (NPSHr) IHC Parts & Services dredge pumps are manufactured for suction diameters from 250 to 1400mm and for low (1-5 bar), medium (2-8 bar) and high (4-15 bar) operating pressures (to 40 bar in series).
