Liverani Miniverter Flexible Impeller Pump

The Liverani MiniverterFlexible Impeller Pumpoffers all the advantages of the FEP MINI and MIDEX pumps but with integrated variable speed control. This combined with the SS316 materials of construction and various sealing and impeller material options, enables these flexible vane pumps to be used in a plethora of different applications.

Flexible impeller pumps are very versatile in applications that are suitable for thanks to several design benefits. Firstly, thanks to their supple vanes they are able to handle not only clean, light fluids, but also viscous, 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 electricfood grade pumpsolution. Their low shear operation also makes the ideal for handling delicate fluids that can be altered by other pump designs.

It is possible to adjust the speed range of the Miniverter flexible impeller pump from 285 to 1400 rpm, and to choose the direction of flow using the integrated potentiometer and rocker switch fitted to the terminal box whilst still retaining its standard IP55 protection rating. Carrying handles and trolleys are available as optional accessories to increase the Miniverter flexible vane pumps’ portability when being used for a variety of site applications.

The beauty of the Mininverter flexible impeller pump is it's versatility. Thanks to the following features it is an option that can be applied to many application requirements.

• Handles solids up to 5mm –年代upple impellers bend to pass viscous fluids and slurries up to 50,000 CP and solids without damage to the pump
• Applies low shear– Ideal for delicate, shear sensitive fluids that can be damaged or altered by other pump types such as cream that gets thicker when whipped.
• Reversible operation– Allows cleaning solution to be ran through after use for hygienic pump applications, and tank to tank transfer applications.
• FDA approved– EPDM and NBR impellers with FDA certification for food grade pump assurance. Stainless sanitary enclosures and Tri-clamp couplings available.
• 年代mooth, steady pumping– Provides a consistent flow ideal for dosing ingredients, chemicals and process fluids and filling finished product into packaging.
• 年代elf-priming up to 6m– Enables the emptying of tanks and drums without a non-return valve or regular manual priming being required.
• Various moutning positions- Allows for versatile installation to fit the pipework at hand
• Various accessories available- Trolley for portability, bypass valve for nozzle dispensing, control panel, variable speed drive, level sensors and dry run protection

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:
