Flensted is owned by Wersing Feinkost GmbH, one of the largest deli salads manufacturers worldwide, with production plants in 7 countries and 4.000 employees.
Flensted has turned to MasoSine Certa pump technology. Indeed, Certa pumps have become the de facto standard for handling the delicate ingredients used in these increasingly popular products – such as chicken, mayonnaise, coleslaw and chickpeas – offering a low shear, gentle pumping action.
Located between Esbjerg and Herning in mainland Denmark, Flensted produces a wide range of popular deli salad products.
“To help pump ingredients such as coleslaw, chicken, mayonnaise, chickpeas, mustard spread and barbecue sauces, we rely on eight Certa pumps, which are located on small trolleys so they can be easily moved around the large production floor, and into different manufacturing halls,” explains maintenance manager Martin Kristensen.
First choice pump
There are many reasons why Flensted opted for MasoSine Certa pumps, not least because they are able to cope with varying viscosities up to 8 million centipoise. In addition, the single rotor design of MasoSine pumps maintains constant volumetric displacement throughout the pumping cycle, providing a smooth and consistent flow profile without the pulsation spikes associated with rotary pumps.
Sine pumps also offer advantages over many other types of positive displacement pumps, such as piston pumps, which are prone to damaging solids, while AODD (air operated double diaphragm) pumps have a pumping action that frequently ‘splits’ bases such as mayonnaise. Ultimately, a trouble-free manufacturing process is a must at deli salad plants as downtime can have costly implications for both the end product and production.
The low shear and gentle action of a MasoSine Pump is unrivalled in its ability to preserve and maintain the integrity of solids such as diced vegetables, fruit, nuts, coleslaw and eggs, as well as bases like mayonnaise and dressings.
Further benefits of Certa pumps include up to 50% less energy consumption for the same flow in comparison with other pump types, and superior suction that cavitation is eliminated.
Quick and efficient
“We are very happy with our six Certa pumps, which get the job done quickly and efficiently,” states Mr. Kristensen.
Deli salads at Flensted need to be manufactured in high volumes, and due to the nature of the ingredients, shelf life is often relatively short. Food plants using Certa pumps will immediately see increased yield and higher efficiency; in fact, flow rates can be adjusted to suit specific production requirements.
Cleanliness and ease of cleaning is another advantage of Certa pumps. Offering EHEDG Type EL Class I as well as EHEDG Type EL Aseptic Class I and 3A certification, the pumps provide full CIP (clean-in-place) capability.
As well as minimising downtime, this quick cleaning procedure also ensures that chemical and water use is reduced, which in turn means that less wastewater requires disposal and the production uptime is increased. So the entire system can carry on manufacturing instead of losing time with cleaning cycles.
“The ease of pump cleaning is outstanding,” concludes Mr Kristensen. “We have semi-CIP cleaning procedures in place, and the Certa pumps are always cleaned quickly, even after pumping very viscous mayonnaise at 20,000 cP.”
