Lobe and piston pumps traditionally used in the food processing industry
deliver excellent benefits including good sanitary qualities and flexibility of
application across multiple products. However, food manufacturers are also
aware of the limitations of this technology. High maintenance costs, low
accuracy, poor volumetric consistency and significant product loss have been
accepted by the food manufacturing industry as inevitable.
All these problems are caused by constant rebuilds, leaking seals, and
leftover product at the bottom of tanks and in pipes.
Eccentric disc pumps offer the most efficient solution for this
situation. Operating on the eccentric movement principle with the disc placed
inside a pump cylinder rotating and creating two distinct pumping chambers, the
pump produces a regular flow rate with low pulsations, low cavitation, and
limited slip or shear even when handling delicate products.
Eccentric disc pump manufacturer Mouvex lists out the advantages of
their pump technology over competing technologies. These include self-priming
design, effective line-stripping, high volumetric consistency against varying
pressure, viscosity changes and wear, no mechanical seals or pulsation, dry-run
capability, totally hygienic (CIP, 3A, EHEDG approved), and low shear
Eccentric disc pumps have proved their worth in various applications in the
food processing industry with their ability to reduce operational costs via
product recovery capability.
A manufacturer of cookies was losing about 50kg of white chocolate
coating per week, and was also forced to clean the pump several times each month.
After changing over to an eccentric disc pump, the manufacturer was able to
achieve trouble-free 24/7 operation.
A sauce manufacturer was rejecting 15-20% of the pouches for not meeting
the pre-determined weight due to poor volumetric consistency of an ECP pump. Changing
to Mouvex’s eccentric disc pump allowed the manufacturer to save on time and
money and significantly reduce product losses.
A yogurt manufacturer was losing more than $100,000 in product per line
per year. The Mouvex eccentric disc pump helped recover over 70% of the product
and significantly improved their bottom line.
Mouvex eccentric disc pumps are also used by
Australian manufacturers to pump chocolate, glucose, galacto-oligosaccharides
(GOS), yoghurt, cream and sauces.
