What characteristic makes flexible impeller pumps particularly suited for marine applications?

Flexible impeller pumps are especially well-suited for marine applications due to their self-priming capability. This feature allows the pump to create a vacuum that brings liquid into the pump without requiring prior filling with fluid, making them highly effective for applications where the pump may be located above the fluid level or where air can become trapped within the system.

Self-priming pumps are advantageous for marine environments, such as bilge pumping, where rapid removal of water is often necessary to maintain safety and prevent sinking. The ability to quickly and efficiently start pumping without needing additional setup or priming procedures makes flexible impeller pumps a practical choice for boaters and marine operators.

In the context of marine systems, the ability to handle various conditions, including low gravity and different fluid levels, is critical. This emphasizes why self-priming capability is a defining feature of flexible impeller pumps in such applications.
