Pumps have no con-rods to ensure
cleanliness
Unlike a conventional hygienic pump fitted with con rods a hygienic pump is fitted with a titanium flexible shaft to ensure there is no possibility of product contamination from pump lubricants.
Willis Europlant, a long established supplier of bottling and packaging equipment to the food and drink, pharmaceutical and dairy industries has specified Netzsch SHF hygienic pumps for their range of carbonating and premix machines The carbonating and premix machines, which have outputs ranging from 1,000 to 30,000 litres/h, are designed to put the fizz into a variety of carbonated products for famous brand soft drinks and alcopops, by providing a high quality carbonating source for the initially uncarbonated product

Dual-stator pump has longer life
A pump's dual-stator system prolongs stator lifetime and reduces lifecycle costs thanks to its manoeuvrability within two-part reusable housing, and when worn, only the stator needs replacing.
Progressive cavity pumps are less complex
Progressive cavity pumps - built from fewer components - include a built-in reserve stator and maintenance-free drive chain, helping to set new standards for long-life and reliability.
Explaining the choice of pump, a Willis Europlant engineer says the SHF produces the pressure required for the process in conjunction with CO2 pressure and temperature monitoring systems.
This ensures CO2 stability in the product and high carbonation saturation at lower final pressures, which cures many filling problems encountered with some products.
Netzsch were also chosen for the quality and technical benefits of their pumps and because of their global presence.
Each carbonator is fitted with a single SHF which, unlike a conventional hygienic pump fitted with con rods connected with pin joints, is fitted with a titanium flexible shaft to ensure there is no possibility of product contamination from lubricants or material.
The use of titanium in the manufacture of flexible shafts also offers greater flexibility.
While a standard stainless steel shaft will do the same job as a titanium shaft, the overall pump length is greater due to its lack of flexibility.
A Willis spokesman says one of the carbonators has been installed by Caledonian Bottlers, who were so impressed by the carbonation stability, savings on product loss and running costs that they ordered two additional machines within a very short time.
