Reliable, Durable Aseptic Process Pump Makes Key Contribution to Success

The Swiss subsidiary of Dutch company DSM Nutritional Products AG makes use of the spray drying methodology when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The procedure uses pump expertise to convey various emulsions into a sprig tower, the place they’re dried into powder. But the feed and booster pump that was getting used proved to be an uncertainty issue as a outcome of the diaphragm required for the pumping process tended to tear when the pump was began up. Generally, such manufacturing interruptions can be corrected via quick upkeep and repair work.
However, it is extremely costly to replace a diaphragm or a whole system. DSM was seeking an alternative and finally made a discover after they talked to the pump experts at Lewa Nikkiso Switzerland, who really helpful a Lewa triplex course of diaphragm pump for the spray tower application. The drive unit features a secure start-up mode that keeps the diaphragm located in the impartial place, and continuous regulation utilizing an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it is simple to fulfill the meals industry’s stringent hygienic provisions.
“Pump know-how performs a central role in drying oil-in-water emulsions for the food and pharmaceutical industries. These emulsions comprise substances similar to nutritional vitamins, carotenoids, or polyunsaturated fatty acids as energetic elements,” explains Natalie Ibald, plant manager of formulations at DSM Nutritional Products AG. “As part of the process chain, each pump is 100 percent built-in into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With the previous system, the danger of unexpected interruptions to this process couldn’t be dominated out. As a result, the totally different emulsions could not be processed additional. In different words, it was not attainable to dry them into powder. The pump diaphragm was the explanation: it was usually too delicate to resist the stress positioned on it when starting up the pump and would rupture. Replacing the diaphragm lowered the system’s service life and sometimes meant that trouble-free operation couldn’t be guaranteed.
In the course of looking for a dependable alternative, DSM got in touch with the Swiss subsidiary of pump producer Lewa.
“We were already acquainted with Lewa Nikkiso Switzerland as a supplier of strong methods with lengthy service lives in the SFP sector. To guarantee trouble-free spray drying, we thought it will be good to join forces with the experts from Lewa and provide you with a design to resolve the technical issues,” says Ibald.
DSM is dedicated to continually enhancing its processes and investing in technology. This commitment, along with prior expertise with the quick service lives of the earlier pumps, led DSM to place special give consideration to reliable function and a robust design in the course of the project planning phase. The list of requirements additionally included a substantial variety of stringent hygienic provisions that needed to be fulfilled.
“Certain foods have provisions regarding microbiological purity that are many occasions extra stringent than those for producing different meals merchandise,” explains Ibald. “This meant that the new feed and booster pump had to meet these more difficult conditions and each sort of contamination needed to be dominated out to supply the widest possible number of merchandise on the system.”
Royal DSM is a worldwide science-oriented company that’s especially active in the areas of nutrition, well being, and sustainable dwelling. pressure gauge ราคา ’s mission is to enhance the lives of all.

After a visit on the company premises to contemplate the spatial and technical parameters, Lewa Nikkiso Switzerland beneficial a kind G3F triplex process diaphragm pump for the spray tower application. This pump features a completely safe start-up operation, since a spring continuously holds the built-in sandwich diaphragm located in a impartial place.
This protects the diaphragm in opposition to incorrect positioning and prevents it from being broken whereas the pump is beginning up, rising system availability considerably. And the Lewa triplex is managed using a strain relief valve that is installed within the hydraulic part and can be configured for the specific state of affairs. Therefore, the pump may be tailored to different operational situations so as to prevent any overloads that will come up. This ensures that the unit has a long service life and clean common operation for the complete system.
In addition to the strain relief valve and the spring control, the design of the diaphragm also plays an important position in guaranteeing reliable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which would possibly be extraordinarily long-lasting. They are related to one another through constructive interlocking in the course of the discharge stroke and mechanical force-fitting through the suction stroke.
This makes the pump hermetically tight and effectively prevents external contamination. As an additional safety function, the DPS monitoring system from Lewa repeatedly screens the condition of the diaphragm. The monitoring unit promptly displays any harm to the device that leads to increased strain within the diaphragm space.
This makes it potential to hold out preventive maintenance and repair work before the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it is often unnecessary to switch the pump off instantly, which signifies that neither the pumping process nor spray drying are negatively impacted to a major extent. If injury to a diaphragm is detected, manufacturing can proceed without any problems as a lot as a deliberate upkeep stop. The elements can then get replaced rapidly and easily by releasing the cassette for the meeting.
The hermetically tight design of the method diaphragm pump does extra than just ensure dependable continuous operation. It can be a central part for fulfilling the stringent hygiene provisions that the spray tower application is subject to. The Lewa triplex maintains a hermetically tight area with out dynamic seals, guaranteeing fully clean and aseptic production circumstances. All pump heads that come into contact with the product are additionally electropolished, which makes it potential to make sure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) utilizing completely different alkaline and acidic agents and with out prior dismantling, it’s possible to fulfill the particular necessities for baby food as properly. The provisions for child meals are 1,000 instances more stringent than these for other merchandise within the food sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we have been capable of rule out any contamination of the pumped medium and clearly meet the required hygiene standard.
The first quote was acquired in June of 2018 and in September of the identical yr, DSM Nutritional Products AG positioned an order for the triplex process diaphragm pump. In operation since April 2019, the pump has turn into an indispensable part of manufacturing on the plant in Sisseln.
“In each phase of the venture, Lewa Nikkiso Switzerland demonstrated fast response times and well-founded expertise, which made a key contribution to implementing the project successfully,” says Ibald. “Our specifications with regard to high quality, robustness, and hygiene were adopted to the letter on this venture. As a outcome, our production has become noticeably extra environment friendly and dependable.”
Lewa develops technologies and offers solutions for the huge array of applications among its customers. Its merchandise are used mainly within the oil and gasoline industry, in gasoline odorization, in refineries and petrochemicals, as properly as within the manufacturing of plastics, detergents, and cleaners. Additional application areas embrace the chemical industry, cosmetics business, pharmaceuticals and biotechnology, meals and beverage trade, and vitality utilities. For extra data, visit
