Flexible vane pumps for handling viscous fluids
The flexible impeller pump, or flexible vane pump as it is otherwise referred to, is part of the positive displacement pump family renowned for its excellent dry self-priming ability. Thanks to this, it is commonly used when the installation means that a good suction lift capacity is required. Flexible impeller pumps are suitable for viscous fluids, slurries and liquids containing solids gas in low pressure applications. Read our guide to flexible impeller pumps here.
Flexible impeller pumps are commonly utilised in the following markets:
Shipping and marine
The impellers of flexible vane pumps can be made from a variety of materials to make them compatible with a range of fluids e.g. EPDM for hot fluids and nitrile for fats and oils. Thanks to its steady pumping mechanism, a flexible impeller pump provides a smooth flow at an even flow rate making it useful for filling and transfer applications. A flexible impeller pump can be ran dry for very short periods of up to 30 seconds in order to obtain a suction lift.
