Dredging Pump

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.

Free delivery of pattern (in good condition) with last cast piece of order to our client or stored in our workshop for future new production but with time-limited or quantity-bound.
2)Cast pieces
Material
The use of the cast pieces requires other chemical analysis and mechanical properties (unless otherwise mentioned on drawing). 
Cast pieces group S (Wear) : 
Impellers, pumphousings, dredge lines (bends, branchpipes, etc.)
Cast pieces group C (Construction) :
Other pieces as pivots, rod eyes, wire sheaves etc.

3)Inspection
Cast pieces are presented in our workshop, for inspection of dimensions and hardness after sandblasting and machining but before conservation and painting. Measurements are carried out by our services and deviations are sanctioned as follows:
At stress concentration area, MT&PT to check the crack, the qualified standard is no crack at these area.
