Vane pumps stand out for their remarkable versatility, effectively handling a diverse range of fluids, including thin liquids, non-lubricating fluids, and even liquids with entrained solids. This versatility extends to their self-priming capabilities, enabling them to draw fluid from a source without the need for an external priming mechanism. This self-priming ability makes vane pumps ideal for applications where fluid reservoirs may be located above the pump.
