The selection of marine centrifugal pumps is a complex and meticulous process that requires consideration of multiple factors to ensure that the selected pump can meet the specific needs of the ship.

Diesel self-priming pumps and electric self-priming pumps each have their own characteristics and advantages, and they need to be weighed according to specific usage scenarios and needs when choosing.

The flow range of centrifugal pumps is usually large, and the flow adjustment methods are flexible and diverse, which is suitable for large flow and high head occasions; while the flow range of positive displacement pumps is relatively small, and the flow stability is better, which is suitable for small flow and occasions that require precise flow control.
