The Liverani bareshaft S/P and hydraulically driven MID flexible impeller pumps are a type of rotary positive displacement pump. Their working principle is similar to that of a centrifugal pump however the impeller vanes are made of a flexible and durable polymer, which deform slightly as they move the liquid. This action enables fragile, shear sensitive fluids including high viscosity mediums containing particles. The SP and MID flexible vane pump models are frequently used on trucks, tractors and boats for a variety of transfer and offloading applications.
Part of the positive displacement pump family are flexible impeller pumps, otherwise known as flexible vane pumps. This pump type is renowned for its ability in dry self-priming. These pumps are therefore most commonly used within applications that are required to have good suction lift capacity. Flexible impeller pumps are ideal for viscous fluids, slurries and liquids containing solids and gas in low pressure applications. Due to their hygienic construction they are also popular as a sanitary pump.
PTO drives are available for the S/P models and the MID flexible impeller pumps can be supplied with an Orbital Hydraulic Motor (50 CC) or with a coupling suitable for a Hydraulic Motor.
