Single-Walled Dredge Pumps
single-walled dredge pumps are `all-round` and used in all types of dredgers. They are designed for typical pump pressures up to 16 bars, and can be excecuted with different types of pump seals such as: stuffing box, mechnical seal or hydro seal.

Double-Walled Dredge Pumps
double-walled dredge pumps are specially designed for high pressures, starting typically from 16 up to 30 bars. The double-walled pump design is based on the concept of pressure compensation between the outer-,  and inner-pump casing. All types of configurations are possible such as 3,4 and 5 vane impellers, and casted or welded outer-casings.

Underwater Dredge Pumps
The underwater dredge pumps are used in cases where the highest possible suction performance is required. They basically have the same possibilities and options as our single-walled pumps have. Depending on our clients' preference they are executed with direct motor drive or integrated gearbox, with or without pressure compensation.
