Pump Shell is a main part of Dredge Pump. 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.
Casting
1)Pattern
Collection in our storehouse. Inspection of pattern in our workshop.
Pieces cast with wrong pattern due to insufficient inspection of pattern are rejected.
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
Materia
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.

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.
