Reliable, Durable Aseptic Process Pump Makes Key Contribution to Success

The Swiss subsidiary of Dutch company DSM Nutritional Products AG uses the spray drying method when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The procedure uses pump expertise to convey varied emulsions into a twig tower, where they’re dried into powder. But the feed and booster pump that was being used proved to be an uncertainty issue as a end result of the diaphragm required for the pumping course of tended to tear when the pump was began up. Generally, such manufacturing interruptions could be corrected via immediate maintenance and restore work.
However, it is very costly to exchange a diaphragm or a complete system. DSM was seeking an alternate and at last made a find once they talked to the pump specialists at Lewa Nikkiso Switzerland, who really helpful a Lewa triplex course of diaphragm pump for the spray tower software. The drive unit contains a secure start-up mode that retains the diaphragm situated in the impartial place, and steady regulation using an built-in monitoring system. Since เกจวัดแรงกด are electropolished and CIP-approved, it is easy to fulfill the food industry’s stringent hygienic provisions.
“Pump expertise performs a central role in drying oil-in-water emulsions for the meals and pharmaceutical industries. These emulsions contain substances corresponding 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 method chain, every 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 earlier system, the risk of unforeseen interruptions to this process couldn’t be ruled out. As a outcome, the completely different emulsions couldn’t be processed further. In other phrases, it was not attainable to dry them into powder. The pump diaphragm was the rationale: it was often too sensitive to face up to the stress positioned on it when beginning up the pump and would rupture. Replacing the diaphragm lowered the system’s service life and typically meant that trouble-free operation couldn’t be assured.
In the course of trying to find a dependable various, DSM obtained in touch with the Swiss subsidiary of pump producer Lewa.
“We have been already acquainted with Lewa Nikkiso Switzerland as a supplier of strong techniques with long service lives in the SFP sector. To เกจวัดแรงดันน้ำ10บาร์ -free spray drying, we thought it might be sensible to join forces with the experts from Lewa and come up with a design to resolve the technical problems,” says Ibald.
DSM is dedicated to repeatedly bettering its processes and investing in know-how. This commitment, along with prior expertise with the quick service lives of the previous pumps, led DSM to put particular focus on dependable perform and a sturdy design in the course of the challenge planning phase. The listing of necessities additionally included a substantial variety of stringent hygienic provisions that had to be fulfilled.
“Certain meals have provisions relating to microbiological purity which may be many occasions more stringent than these for producing different meals merchandise,” explains Ibald. “This meant that the model new feed and booster pump needed to meet these more challenging circumstances and every sort of contamination had to be ruled out to provide the widest possible variety of products on the system.”

After a go to on the company premises to assume about the spatial and technical parameters, Lewa Nikkiso Switzerland beneficial a kind G3F triplex course of diaphragm pump for the spray tower utility. This pump features a utterly safe start-up operation, since a spring constantly holds the integrated sandwich diaphragm located in a neutral 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 controlled using a strain aid valve that’s installed in the hydraulic part and can be configured for the precise situation. Therefore, the pump can be tailored to completely different operational conditions to be able to prevent any overloads that will come up. This ensures that the unit has a protracted service life and easy regular operation for the complete system.
In addition to the pressure reduction valve and the spring management, the design of the diaphragm also plays an important role in guaranteeing dependable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which are extraordinarily long-lasting. They are connected to each other by way of optimistic interlocking in the course of the discharge stroke and mechanical force-fitting in the course of the suction stroke.
This makes the pump hermetically tight and effectively 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 damage to the device that leads to elevated stress within the diaphragm house.
This makes it potential to carry out preventive maintenance and repair work earlier than the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it is often pointless to switch the pump off instantly, which means 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 issues up to a planned upkeep cease. The components 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 simply ensure dependable continuous operation. It can be a central part for fulfilling the stringent hygiene provisions that the spray tower software is subject to. The Lewa triplex maintains a hermetically tight house with out dynamic seals, guaranteeing utterly clear and aseptic manufacturing situations. All pump heads that come into contact with the product are additionally electropolished, which makes it potential to ensure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) using completely different alkaline and acidic agents and without prior dismantling, it is possible to fulfill the special requirements for baby food as properly. The provisions for baby food are 1,000 instances more stringent than these for other merchandise in the food sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we were capable of rule out any contamination of the pumped medium and clearly meet the required hygiene standard.
The first quote was received in June of 2018 and in September of the identical yr, DSM Nutritional Products AG positioned an order for the triplex course of diaphragm pump. In operation since April 2019, the pump has turn out to be an indispensable a part of production at the plant in Sisseln.
“In each part of the project, Lewa Nikkiso Switzerland demonstrated quick response instances and well-founded experience, which made a key contribution to implementing the venture successfully,” says Ibald. “Our specifications with regard to high quality, robustness, and hygiene were adopted to the letter in this venture. As a outcome, our manufacturing has turn out to be noticeably extra efficient and reliable.”
Lewa develops technologies and supplies solutions for the vast array of functions among its clients. Its products are used mainly within the oil and fuel industry, in gasoline odorization, in refineries and petrochemicals, in addition to within the production of plastics, detergents, and cleaners. Additional software areas embody the chemical trade, cosmetics industry, pharmaceuticals and biotechnology, meals and beverage industry, and vitality utilities. For extra data, visit
