Reliable, Durable Aseptic Process Pump Makes Key Contribution to Success

The Swiss subsidiary of Dutch company DSM Nutritional Products AG uses the spray drying technique when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The process makes use of pump technology to convey numerous emulsions into a sprig tower, where they are dried into powder. But the feed and booster pump that was being used proved to be an uncertainty factor because the diaphragm required for the pumping process tended to tear when the pump was began up. Generally, such production interruptions may be corrected through quick upkeep and repair work.
However, it is extremely expensive to exchange a diaphragm or a whole system. DSM was seeking an alternate and finally made a discover after they talked to the pump specialists at Lewa Nikkiso Switzerland, who beneficial a Lewa triplex course of diaphragm pump for the spray tower utility. The drive unit features a secure start-up mode that keeps the diaphragm situated in the impartial position, and continuous regulation utilizing an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it’s simple to satisfy the meals industry’s stringent hygienic provisions.
“Pump expertise performs a central position in drying oil-in-water emulsions for the food and pharmaceutical industries. These emulsions include substances similar to vitamins, carotenoids, or polyunsaturated fatty acids as active components,” explains Natalie Ibald, plant supervisor of formulations at DSM Nutritional Products AG. “As part of the process chain, each pump is one hundred pc built-in into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With the previous system, the chance of unexpected interruptions to this course of couldn’t be dominated out. As a result, the different emulsions couldn’t be processed further. In other words, it was not possible to dry them into powder. The pump diaphragm was the rationale: it was usually too sensitive to resist the stress placed on it when beginning up the pump and would rupture. Replacing the diaphragm lowered the system’s service life and generally meant that trouble-free operation could not be assured.
In the course of searching for a dependable different, DSM obtained in touch with the Swiss subsidiary of pump manufacturer Lewa.
“We have been already familiar with Lewa Nikkiso Switzerland as a supplier of sturdy techniques with long service lives in the SFP sector. To ensure trouble-free spray drying, we thought it might be good to affix forces with the experts from Lewa and provide you with a design to unravel the technical problems,” says Ibald.
DSM is dedicated to continually enhancing its processes and investing in expertise. This commitment, along with prior experience with the short service lives of the previous pumps, led DSM to put special concentrate on dependable function and a strong design in the course of the challenge planning part. The list of requirements additionally included a considerable variety of stringent hygienic provisions that needed to be fulfilled.
“Certain meals have provisions relating to microbiological purity which might be many times more stringent than these for producing different meals products,” explains Ibald. “This meant that the new feed and booster pump needed to meet these more challenging situations and each type of contamination had to be dominated out to provide the widest attainable number of products on the system.”

After a visit at the firm premises to suppose about the spatial and technical parameters, Lewa Nikkiso Switzerland recommended a type G3F triplex process diaphragm pump for the spray tower software. This pump includes a completely secure start-up operation, since a spring continuously holds the built-in sandwich diaphragm located in a impartial position.
This protects the diaphragm towards incorrect positioning and prevents it from being damaged while the pump is starting up, increasing system availability substantially. And the Lewa triplex is managed utilizing a pressure reduction valve that’s installed in the hydraulic half and could be configured for the specific situation. Therefore, the pump could be tailored to different operational conditions so as to prevent any overloads which will arise. This ensures that the unit has an extended service life and easy regular operation for the entire system.
In addition to the strain aid valve and the spring management, the design of the diaphragm also performs an necessary function in guaranteeing reliable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms that are extremely long-lasting. They are connected to one another via constructive interlocking through the discharge stroke and mechanical force-fitting through the suction stroke.
This makes the pump hermetically tight and successfully prevents exterior contamination. As a further safety function, the DPS monitoring system from Lewa continuously displays the condition of the diaphragm. The monitoring unit promptly displays any harm to the system that results in elevated strain within the diaphragm space.
This makes it attainable to hold out preventive maintenance and restore work before the diaphragm even begins to rupture and doubtlessly contaminates the pumped fluid. Thus, it is normally unnecessary to change the pump off instantly, which means that neither the pumping course of nor spray drying are negatively impacted to a significant extent. If harm to a diaphragm is detected, production can proceed without any problems as much as a deliberate upkeep cease. The parts can then be replaced rapidly and easily by releasing the cassette for the assembly.
The hermetically tight design of the process diaphragm pump does more than just ensure reliable continuous operation. It is also a central component for fulfilling the stringent hygiene provisions that the spray tower software is topic to. The Lewa triplex maintains a hermetically tight house with out dynamic seals, guaranteeing fully clear and aseptic manufacturing circumstances. All pump heads that come into contact with the product are also electropolished, which makes it attainable to ensure FDA-compliant pump operation.
Because pressure gauge trerice ราคา could be cleaned in place (CIP) utilizing completely different alkaline and acidic agents and without prior dismantling, it is possible to satisfy the particular necessities for child food as properly. The provisions for baby food are 1,000 occasions more stringent than those for other products in the food sector. Thanks to the hermetically tight design, electropolishing, and CIP cleaning, we have been able to rule out any contamination of the pumped medium and clearly meet the required hygiene commonplace.
The first quote was acquired in June of 2018 and in September of the same year, DSM Nutritional Products AG positioned an order for the triplex course of diaphragm pump. In operation since April 2019, the pump has become an indispensable a part of production on the plant in Sisseln.
“In every phase of the challenge, Lewa Nikkiso Switzerland demonstrated quick response instances and well-founded experience, which made a key contribution to implementing the challenge efficiently,” says Ibald. “Our specs with regard to quality, robustness, and hygiene have been adopted to the letter in this challenge. As a result, our production has turn out to be noticeably extra efficient and dependable.”
