In CIP applications, the pumps can be arranged in a series to take advantage of their unique “disc/cylinder” design. Because the pressure at the pump inlet is higher than at the outlet, the disc lifts from the pump cylinder, permitting passage of the water or cleaning solutions to flow through the pump, thoroughly cleaning the pump chambers. This unique feature eases the cleaning process and reduces cycle times so the pump can be put back into operation as quickly as possible.

Meeting the Regulatory Needs of Food Processors

Recognizing that food processors require the best, most reliable pump technology in order to satisfy the EC 1935/2004 regulation, as well as other food-processing regulatory standards, Mouvex has created the SLS Series Seal-less Drive Eccentric Disc Pump. These pumps have been designed for use in the food, cosmetic and pharmaceutical industries, all of which require extremely hygienic operations.

What sets the SLS Series pumps apart is an innovative new design that incorporates a double-wall bellows into the pump’s construction, along with monitoring that is done via pressure switch. By mounting the pressure switch on the bellows flange, the bellows becomes an independent subassembly within the pump, resulting in easier and safer operation. The design has helped the SLS pumps earn approval from EC 1935/2004, along with 3A, FDA and EHEDG, for use in food-processing applications.

Other improvements in the SLS Series pumps include the ability to handle differential pressures up to 10 bar (145 psi) and high-quality machined parts for optimum surface finish, which are also compatible with SMS, DIN11851, DIN11864 and ASME-BPE clamp flanges.

Along with these advancements, the SLS Series pumps offer the features that Mouvex eccentric disc pumps have become known for, including:

completely seal-less design,

low shear rate,

self-priming and dry-run capabilities,

exceptional volumetric consistency,

strong vacuum and compression effect for line stripping,

only two wear parts,

maintenance that can be performed while the pump is online,

optional heating jacket.

Mouvex is currently offering the SLS Series pumps — which replace the landmark C Series pumps that were introduced in1996 — in SLS1, SLS2, SLS3, SLS4 and SLS8 sizes, with the SLS12, SLS18, SLS24 and SLS36 models expected to be released to the market in 2014.

The Do's and Dont's of Food Process Pumps

Conclusion: There are many potential pitfalls in food processing. Leaks lead to an unrecoverable loss of product and create unexpected cleanup costs. As mentioned, contamination during production brings with it a whole slew of far-reaching problems for the processor. Because of the ironclad need to produce food of the highest quality in every batch, strict regulations have been put into place to help ensure that both the producer and consumer are protected. Thanks to an innovative design that has stood the test of time for more than a century, eccentric disc pump technology stands ready to help food processors confidently overcome every challenge they may face.
