The Liverani All in One is an innovative flexible impeller pump, designed primarily for the wine making market as a system to monitor and schedule all transfer operations. It is supplied mounted onto a stainless-steel trolley meaning it can be easily transported and used throughout the winery, and is supplied with inverter drive to allow the user to vary the motor speed to change the flow capacity.

Complete with 7” multi-function touch screen control panel, this flexible vane pump allows the operator to programme the amount to be transferred as well as record and review actual transfer applications that have taken place. The start/stop, speed variation and rotation of this complete flexible impeller pump solution can also be remotely operated from a radio control.

The following operations can be undertaken:

  1. Free transfer – where the user would manually stop the pump after they’ve dispensed what they want to
  2. Preset volume transfer – where the user sets how much they want to transfer, and the pump will automatically stop once it reaches that amount
  3. Barrel filling - repeated filling of a preset volume to fill multiple barrels
  4. Pump over - can be set up pause cycles and to empty pipes after transfer is over

For traceability, it is possible to record and save each transfer operation along with the operation name, type of wine or reference batch. This data can be exported from the control panel onto a USB for analysis on a computer. There is also the ability to connect to additional devices such as a press, filter, or bottling.

The Liverani All in One includes a high precision magnetic food grade flow meter for monitoring the amount of fluid that has been dispensed in that operation, as well as give an indication of flow rate. This flexible impeller pump also benefits from dry run detection which will stop the pump to prevent damage.

The flexible impeller design is ideal as a wine transfer pump as its supple vanes allows the handling of solids which may be present such as grape skin and seeds. The EPDM and NBR impellers are able to be supplied with FDA Certification, making them a popular food grade pump solution.

We received an enquiry from a contract winemaker based in the UK. They required a food grade pump to transfer wine at temperatures between 2 and 65⁰C, with a maximum flow rate of 15,000 litres per hour and ideally the option of variable speed to enable more control. Due to the nature of their application and the specifications required, we supplied the Liverani All in One Flexible Impeller Pump which was a perfect fit for their requirements.
