Enquiry

We received an enquiry from a Marine Dredging company that required a self-priming pump for transferring sea water containing small amounts of sand. They specified to us that the casing material be cast iron to save costs, we normally recommend bronze for sea water applications. They required the sea water dredging pump to have 4” ports and transfer 75m³/hr at 12m head.

Solution

We selected a horizontal self-priming centrifugal pump with a cast iron casing and bronze impeller from our CA range. The impeller type fitted to this pump allows passage of 10% sand content in the sea water. This sea water pump has a 4” suction and discharge and we fitted a hard faced mechanical seal to cope with the abrasive sand content.
