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 method when producing vitamin and carotenoid powders for the pharmaceutical and food industries. ร้านซ่อมเครื่องวัดความดัน makes use of pump expertise to convey varied emulsions into a sprig tower, where they are dried into powder. But the feed and booster pump that was getting used proved to be an uncertainty factor as a end result of the diaphragm required for the pumping course of tended to tear when the pump was started up. Generally, such production interruptions could be corrected through quick upkeep and repair work.
However, it is rather expensive to switch a diaphragm or a whole system. DSM was seeking an alternate and at last made a discover once they talked to the pump specialists at Lewa Nikkiso Switzerland, who recommended a Lewa triplex course of diaphragm pump for the spray tower software. The drive unit features a secure start-up mode that retains the diaphragm positioned in the impartial position, and continuous regulation using an built-in monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it is straightforward to satisfy the meals industry’s stringent hygienic provisions.
“Pump expertise plays a central function in drying oil-in-water emulsions for the food and pharmaceutical industries. These emulsions contain substances corresponding to nutritional vitamins, carotenoids, or polyunsaturated fatty acids as lively elements,” explains Natalie Ibald, plant manager of formulations at DSM Nutritional Products AG. “As part of the method chain, each pump is 100 percent integrated into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With the earlier system, the chance of unexpected interruptions to this course of couldn’t be ruled out. As a end result, the completely different emulsions couldn’t be processed further. In other words, it was not potential to dry them into powder. The pump diaphragm was the rationale: it was usually too delicate to resist the stress positioned on it when beginning 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 assured.
In the course of looking for a dependable various, DSM obtained in touch with the Swiss subsidiary of pump manufacturer Lewa.
“We were already acquainted with Lewa Nikkiso Switzerland as a provider of sturdy systems with lengthy service lives in the SFP sector. To ensure trouble-free spray drying, we thought it might be sensible to hitch forces with the specialists from Lewa and give you a design to solve the technical issues,” says Ibald.
DSM is dedicated to continually improving its processes and investing in technology. This commitment, together with prior expertise with the quick service lives of the earlier pumps, led DSM to position special concentrate on reliable operate and a strong design through the venture planning part. The record of requirements additionally included a considerable number of stringent hygienic provisions that had to be fulfilled.
“Certain foods have provisions relating to microbiological purity which may be many occasions 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 difficult situations and each type of contamination had to be ruled out to provide the widest potential number of products on the system.”

After a visit on the company premises to consider the spatial and technical parameters, Lewa Nikkiso Switzerland really helpful a type G3F triplex process diaphragm pump for the spray tower application. This pump contains a utterly secure start-up operation, since a spring repeatedly holds the built-in sandwich diaphragm situated in a neutral place.
This protects the diaphragm against incorrect positioning and prevents it from being broken whereas the pump is beginning up, growing system availability considerably. And the Lewa triplex is managed utilizing a strain relief valve that is put in within the hydraulic part and could be configured for the specific state of affairs. Therefore, the pump can be tailored to completely different operational situations to have the ability to stop any overloads that may arise. This ensures that the unit has an extended service life and smooth common operation for the entire system.
In addition to the pressure aid valve and the spring management, the design of the diaphragm additionally plays an essential role in guaranteeing dependable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which may be extraordinarily long-lasting. They are related to one another via optimistic interlocking through the discharge stroke and mechanical force-fitting during the suction stroke.
This makes the pump hermetically tight and effectively prevents exterior contamination. As a further security function, the DPS monitoring system from Lewa constantly monitors the condition of the diaphragm. The monitoring unit promptly displays any damage to the gadget that leads to elevated stress within the diaphragm house.
This makes it potential to carry out preventive maintenance and repair work before the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it’s normally pointless to change the pump off immediately, which signifies that neither the pumping process 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 maintenance cease. The elements can then get replaced rapidly and simply by releasing the cassette for the assembly.
The hermetically tight design of the process diaphragm pump does extra than just ensure dependable steady 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 house without dynamic seals, guaranteeing utterly clean and aseptic production circumstances. All pump heads that come into contact with the product are additionally electropolished, which makes it attainable to make sure FDA-compliant pump operation.
Because the pump can be cleaned in place (CIP) utilizing different alkaline and acidic brokers and without prior dismantling, it is potential to fulfill the particular requirements for baby food as nicely. The provisions for baby meals are 1,000 times more stringent than those for other merchandise in the food sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we have been able to rule out any contamination of the pumped medium and clearly meet the required hygiene commonplace.
The first quote was received in June of 2018 and in September of the identical 12 months, DSM Nutritional Products AG placed an order for the triplex course of diaphragm pump. In operation since April 2019, the pump has turn out to be an indispensable part of manufacturing on the plant in Sisseln.
“In each part of the venture, Lewa Nikkiso Switzerland demonstrated fast response instances and well-founded experience, which made a key contribution to implementing the project successfully,” says Ibald. “Our specs with regard to quality, robustness, and hygiene were followed to the letter in this project. As a end result, our production has turn into noticeably more environment friendly and reliable.”
Lewa develops applied sciences and provides solutions for the huge array of applications amongst its customers. Its products are used mainly in the oil and fuel business, in fuel odorization, in refineries and petrochemicals, as nicely as within the manufacturing of plastics, detergents, and cleaners. Additional utility areas include the chemical industry, cosmetics industry, prescribed drugs and biotechnology, meals and beverage industry, and power utilities. For extra information, go to
