The Liverani All in One is an innovative flexible impeller pump, designed primarily for the wine making and distillery 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.

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.

Ensuring compatibility with the fluid being pumped is a vital part of flexible impeller pump specification to avoid swelling, erosion and even melting of the impellers. Our Liverani impellers are available in Natural Rubber, Neoprene, NBR, EPDM and Silicon. Upon disclosure of the fluid you are handling we will establish the best solution. Or view our chemical compatibility table here.

Yes. The pump is constructed of a 316 Stainless Steel pump head and the impellers are available in food grade NBR or EPDM. They can also be supplied with food safe Tri-clamp fittings to meet ISO 2852 and with Stainless Steel motor enclosure on request.

Unfortunately not! The fluid acts as a lubricant and coolant as the pump runs, so as well as risking the impeller melting, the mechanical seal could crack and result in leaking if it overheats. Consider a dry run protection device or float switch if there is risk of this happening.

Flexible impeller pumps are a relatively low cost solution compared to other pumps able to handle aggressive fluids, solids and viscous liquids. They are however limited in their pressure capabilities, so are usually reserved for more steady duty requirements.

Yes. Being able to operate in both directions makes flexible impeller pumps ideal for tank to tank transfer as well as returning excess liquid out of the pipework when transfer is complete.

Yes. The impellers are made of a supple rubber type material able to bend around soft solids without damage or jamming.

Yes! Thanks to the nature of the flexible vanes meaning that they maintain a tight seal with the internal pump walls they are ideal for where suction lift is required.

To ensure you get the correct Liverani pump spares, we need to identify the exact pump model you have. Please advise us of the model number and serial number (referred to as Commessa) which can be found on the pump label which is usually on the top of the pump body.

Castle Pumps can supply all Liverani pump parts detailed on the spare parts list including impellers, mechanical seals, casing and o-rings.

Liverani pumps are available with additional accessories including inverters for variable speed, trolley for portability, level sensors, control panel, remote control operation and bypass valve for nozzle dispensing.
