The Liverani RID Series is a range of gear box driven柔性葉輪泵。By using a gear box with twin output shafts, double headed options are available to generate either larger flow rates or higher heads. The RID MAXI DOUBLE 2Q effectively doubles the flow of the RID MAXI 80, whereas the RID MAXI DOUBLE 2H effectively doubles the head.

柔性葉輪泵在適用於多種設計效益的應用中非常多功能。首先，由於他們的柔軟葉片，他們不僅能夠處理幹淨，輕質的流體，而且還可以處理粘稠的固體升起的漿料。其次，葉輪的多種材料是與許多液體相容的平均值。NBR用於脂肪和燃料，用於化學品和熱流體的EPDM和水基液體的天然橡膠。具有EPDM和NBR葉輪的柔性葉片泵能夠提供FDA認證，使其成為流行的電氣food grade pumpsolution. Their low shear operation also makes the ideal for handling delicate fluids that can be altered by other pump designs.

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 the emptying of tanks, sumps and other containers. The RID flexible vane pumps are widely used in transferring, filling & emptying applications for medium to high viscosity fluids or for operating at low rotational speeds for shear sensitive fluids. As the pumps are close coupled, the various inlet and outlet configurations can be better taken advantage of (a possible draw back to the GR series of flexible impeller pumps).

Flexible impeller pumps are a versatile design of pump for relatively low pressure applications, mainly with thanks to their impellers being produced in a wide range of materials for fluid compatibility including food grade applications. As the impellers are made of a supple, rubber type material that is able to bend, flexible vane pumps are also able to handle viscous fluids and those with solid content without causing damage. They also apply little shear to the pumped medium, making them suitable for shear sensitive fluids and their ability to be operated in reverse makes them ideal for tank to tank transfer. These design benefits make them suited to many applications including:
