The customer contacted us requiring 4 x self-priming sea water injection pumps in stainless steel 316. The customer could not accept bronze material for this application, which is usually the recommended material due to its lower cost and quicker lead times. 


We selected 4 of our CA 150-25 long coupled self-priming centrifugal pumps in stainless steel 316. The long coupled design separates the pump from the motor allowing easier maintenance and also reducing the risk of any fluid entering the motor in the event of a mechanical seal failure. These sea water pumps are fitted with 4 pole motors running at 1450RPM, the slower motor speed reduces the wear on the centrifugal pump in the long term, making them perfect for 24/7 applications such as this. We also supplied a 2 year recommended spare parts package to further avoid any potential issues for the customer.
