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 food industries. The process uses pump expertise to convey varied emulsions into a twig tower, the place they are dried into powder. But เกจ์วัดแรงดันแก๊ส and booster pump that was getting 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 started up. Generally, such production interruptions may be corrected via instant maintenance and restore work.
However, it is rather costly to exchange a diaphragm or an entire system. DSM was looking for an alternative and eventually made a find once they talked to the pump specialists at Lewa Nikkiso Switzerland, who really helpful a Lewa triplex process diaphragm pump for the spray tower software. The drive unit features a protected start-up mode that keeps the diaphragm situated in the neutral position, and continuous regulation using an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it is simple to meet the meals industry’s stringent hygienic provisions.
“Pump know-how plays a central position in drying oil-in-water emulsions for the meals and pharmaceutical industries. These emulsions contain substances such as nutritional vitamins, carotenoids, or polyunsaturated fatty acids as lively elements,” explains Natalie Ibald, plant supervisor of formulations at DSM Nutritional Products AG. “As a part of the process chain, every 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 earlier system, the chance of unforeseen interruptions to this process couldn’t be ruled out. As a end result, the totally different emulsions couldn’t be processed further. In different words, it was not attainable to dry them into powder. The pump diaphragm was the reason: it was usually too delicate to withstand 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 guaranteed.
In the course of trying to find a dependable different, DSM obtained in touch with the Swiss subsidiary of pump producer Lewa.
“We had been already acquainted with Lewa Nikkiso Switzerland as a supplier of sturdy systems with long service lives within the SFP sector. To guarantee trouble-free spray drying, we thought it might be good to join forces with the consultants from Lewa and give you a design to unravel the technical problems,” says Ibald.
DSM is committed to repeatedly bettering its processes and investing in know-how. This commitment, together with prior expertise with the quick service lives of the earlier pumps, led DSM to place particular focus on reliable operate and a robust design during the project planning part. The listing of requirements also included a considerable variety of stringent hygienic provisions that needed to be fulfilled.
“Certain foods have provisions regarding microbiological purity that are many times extra stringent than those for producing other food merchandise,” explains Ibald. “This meant that the new feed and booster pump had to meet these tougher conditions and every type of contamination needed to be dominated out to supply the widest potential number of products on the system.”

After a go to on the company premises to assume about the spatial and technical parameters, Lewa Nikkiso Switzerland really helpful a kind G3F triplex process diaphragm pump for the spray tower application. This pump includes a fully safe start-up operation, since a spring constantly holds the integrated sandwich diaphragm positioned in a neutral position.
This protects the diaphragm in opposition to incorrect positioning and prevents it from being broken while the pump is starting up, growing system availability considerably. And the Lewa triplex is managed using a stress reduction valve that’s put in in the hydraulic part and may be configured for the precise state of affairs. Therefore, the pump could be adapted to totally different operational situations so as to prevent any overloads that may arise. This ensures that the unit has a protracted service life and easy regular operation for the entire system.
In addition to the pressure relief valve and the spring management, the design of the diaphragm also plays an necessary position in ensuring dependable 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 during the suction stroke.
เกจวัดแรงดันน้ำ makes the pump hermetically tight and effectively prevents exterior contamination. As a further safety characteristic, the DPS monitoring system from Lewa continuously screens the situation of the diaphragm. The monitoring unit promptly displays any injury to the gadget that results in increased pressure within the diaphragm area.
This makes it potential to hold out preventive upkeep and repair work earlier than the diaphragm even begins to rupture and doubtlessly contaminates the pumped fluid. Thus, it’s usually pointless to modify the pump off right away, which signifies that neither the pumping course of nor spray drying are negatively impacted to a significant extent. If damage to a diaphragm is detected, manufacturing can continue with none problems up to a deliberate upkeep cease. The elements can then get replaced rapidly and simply by releasing the cassette for the meeting.
The hermetically tight design of the process diaphragm pump does more than just ensure reliable steady operation. It can be a central component for fulfilling the stringent hygiene provisions that the spray tower application is subject to. The Lewa triplex maintains a hermetically tight area without dynamic seals, guaranteeing fully clean and aseptic production circumstances. All pump heads that come into contact with the product are also electropolished, which makes it possible to make sure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) utilizing different alkaline and acidic brokers and with out prior dismantling, it is potential to fulfill the particular requirements for child food as nicely. The provisions for baby food are 1,000 instances extra stringent than those for other products in the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we were in a place to rule out any contamination of the pumped medium and clearly meet the required hygiene normal.
The first quote was obtained in June of 2018 and in September of the same yr, DSM Nutritional Products AG placed an order for the triplex process 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 phase of the project, Lewa Nikkiso Switzerland demonstrated quick response instances and well-founded experience, which made a key contribution to implementing the challenge efficiently,” says Ibald. “Our specifications with regard to quality, robustness, and hygiene were followed to the letter in this venture. As a outcome, our production has turn into noticeably more environment friendly and reliable.”
Lewa develops applied sciences and supplies options for the huge array of purposes amongst its customers. Its merchandise are used mainly within the oil and gas business, in gas odorization, in refineries and petrochemicals, in addition to in the manufacturing of plastics, detergents, and cleaners. Additional utility areas include the chemical business, cosmetics industry, prescribed drugs and biotechnology, meals and beverage industry, and power utilities. For more information, visit
