Reliable, Durable Aseptic Process Pump Makes Key Contribution to Success
The Swiss subsidiary of Dutch firm DSM Nutritional Products AG uses the spray drying method when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The process makes use of pump technology to convey varied emulsions into a spray tower, the place they are dried into powder. But the feed and booster pump that was getting used proved to be an uncertainty issue because the diaphragm required for the pumping process tended to tear when the pump was began up. Generally, such production interruptions could be corrected by way of immediate maintenance and repair work.
However, it is very expensive to exchange a diaphragm or a complete system. DSM was looking for another and finally made a discover after they talked to the pump experts at Lewa Nikkiso Switzerland, who recommended 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 neutral position, and continuous regulation using an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it's easy to satisfy the meals industry’s stringent hygienic provisions.
one hundred PERCENT INTEGRATION

“Pump know-how plays a central position in drying oil-in-water emulsions for the food and pharmaceutical industries. These emulsions contain substances similar to vitamins, carotenoids, or polyunsaturated fatty acids as active elements,” explains Natalie Ibald, plant manager of formulations at DSM Nutritional Products AG. “As part of the method chain, each pump is one hundred pc integrated 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 course of couldn’t be dominated out. As a outcome, the completely different emulsions couldn't be processed further. In other phrases, it was not possible 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 generally meant that trouble-free operation couldn't be guaranteed.
FINDING THE RIGHT PARTNER

In the course of looking for a reliable various, DSM received in contact with the Swiss subsidiary of pump producer Lewa.
“We were already conversant in Lewa Nikkiso Switzerland as a provider of robust methods with lengthy service lives in the SFP sector. To guarantee trouble-free spray drying, we thought it would be good to hitch forces with the consultants from Lewa and give you a design to solve the technical problems,” says Ibald.
DSM is dedicated to continually bettering its processes and investing in know-how. This commitment, along with prior experience with the brief service lives of the earlier pumps, led DSM to position special concentrate on reliable operate and a strong design through the project planning phase. The list of requirements additionally included a considerable number of stringent hygienic provisions that needed to be fulfilled.
“Certain meals have provisions concerning microbiological purity which are many occasions extra stringent than these for producing different meals merchandise,” explains Ibald. “This meant that the brand new feed and booster pump needed to meet these tougher circumstances and each kind of contamination had to be dominated out to provide the widest attainable variety of products on the system.”

GUARANTEED SAFE START-UP OPERATION

After a go to on the firm premises to consider the spatial and technical parameters, Lewa Nikkiso Switzerland recommended a kind G3F triplex course of diaphragm pump for the spray tower application. This pump contains a fully safe start-up operation, since a spring continuously holds the built-in sandwich diaphragm positioned in a impartial place.
This protects the diaphragm against incorrect positioning and prevents it from being broken while the pump is starting up, rising system availability substantially. And the Lewa triplex is managed utilizing a strain reduction valve that's installed in the hydraulic part and can be configured for the specific scenario. Therefore, the pump can be adapted to different operational conditions to be able to stop any overloads which will arise. This ensures that the unit has a protracted service life and smooth regular operation for the entire system.
THE POWER OF DESIGN

In addition to the pressure aid valve and the spring control, the design of the diaphragm additionally performs an necessary position in making certain dependable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which are extremely long-lasting. They are related to each other by way of constructive interlocking during the discharge stroke and mechanical force-fitting through the suction stroke.
This makes the pump hermetically tight and successfully prevents external contamination. As pressure gauge weksler ราคา , the DPS monitoring system from Lewa continuously monitors the condition of the diaphragm. The monitoring unit promptly shows any damage to the system that leads to increased strain in the diaphragm space.
This makes it attainable to carry out preventive maintenance and restore work earlier than the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it's often unnecessary to modify the pump off right away, which implies that neither the pumping process nor spray drying are negatively impacted to a major extent. If harm to a diaphragm is detected, manufacturing can continue with none problems as much as a deliberate upkeep cease. The parts can then get replaced quickly and simply by releasing the cassette for the assembly.
ASEPTIC, FDA-COMPLIANT OPERATION

The hermetically tight design of the method diaphragm pump does more than just ensure reliable steady operation. It can be a central part for fulfilling the stringent hygiene provisions that the spray tower utility is subject to. The Lewa triplex maintains a hermetically tight house with out dynamic seals, guaranteeing fully clear and aseptic manufacturing situations. All pump heads that come into contact with the product are also electropolished, which makes it attainable to ensure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) using completely different alkaline and acidic brokers and without prior dismantling, it's attainable to satisfy the special requirements for baby food as well. The provisions for baby food are 1,000 instances extra stringent than these for other merchandise in the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we had been able to rule out any contamination of the pumped medium and clearly meet the required hygiene standard.
QUICK RESPONSE TIMES AND WELL-FOUNDED EXPERTISE

The first quote was obtained in June of 2018 and in September of the identical yr, DSM Nutritional Products AG placed 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 occasions and well-founded experience, which made a key contribution to implementing the challenge efficiently,” says Ibald. “Our specifications with regard to high quality, robustness, and hygiene have been adopted to the letter in this challenge. As a outcome, our manufacturing has turn out to be noticeably extra environment friendly and reliable.”
