What is a key advantage of a flexible vane pump?

A flexible vane pump is designed with the ability to self-prime, which is a significant advantage. This characteristic allows the pump to start drawing fluid without the need for external priming assistance or flooding the pump with liquid before operation. Self-priming is particularly beneficial in applications where the pump may need to operate in conditions where the fluid source is lower than the pump level or where the system requires rapid start-up times.

While low maintenance, handling high pressures, and efficient operation with low noise may be relevant features of other pump types, they do not specifically highlight the unique advantage associated with flexible vane pumps. The self-priming capability enhances their versatility and ease of use, making them ideal for various industrial applications where maintaining fluid flow is critical from the moment the pump is activated.
