The double-walled pump design is based on the principle of pressure compensation between the outer and inner pump casings. Various configurations are available, including 3, 4 and 5-vane impellers, with options for cast or welded outer casings.

The outer casing of the DW pumps is lightweight and cast in two halves that fit securely around the inner pump casing.
