The Liverani EP MINI range of close-coupled stainless steel flexible impeller pumps are a popular choice due to their compact and cost-effective design. The operation of these pumps is similar to the centrifugal design, but as the impeller vanes are a flexible polymer, they bend as they force the liquid through.
Flexible impeller pumps are very versatile in applications that are suitable for thanks to several design benefits. Firstly, thanks to their supple vanes, Liverani EP MINI flexible vane pumps are able to handle not only clean, light fluids but also viscious, solid laden slurries. Secondly, the multiple materials the impellers are made out of mean they are compatible with many fluids e.g. NBR for fats and fuels, EPDM for chemicals and hot fluids and natural rubber for water-based liquids. Flexible vane pumps with EPDM and NBR impellers are able to be supplied with FDA Certification, making them a popular food grade pump solution. Their low shear operation also makes them ideal for handling delicate fluids that can be altered by other pump designs.
Liverani EP MINI flexible impeller pumps are renowned for their dry self-priming capability, making them ideal for applications where good suction lift capacity is needed, such as emptying tanks, sumps, and other containers. The flexible vane pumps are widely used in transferring, filling & emptying applications, but when used in conjunction with a carrying handle and their integral on/off reversing switch, they are also a very reliable utility pump solution popular for a tank to tank transfer.

FAQs
Flexible impeller pumps are part of the positive displacement pump family. They consist of a rotating rubber impeller with supple vanes attached. As the casing is smaller than the vanes, they must bend and then straighten as the impeller turns to conform to shape of the pump internal walls. The vacuum created push the fluid round from the inlet to the outlet.
