The Swiss subsidiary of Dutch firm DSM Nutritional Products AG uses the spray drying technique when producing vitamin and carotenoid powders for the pharmaceutical and food industries. The process makes use of pump technology to convey numerous emulsions into a spray tower, the place they are dried into powder. But the feed and booster pump that was being used proved to be an uncertainty factor as a end result of the diaphragm required for the pumping process tended to tear when the pump was started up. Generally, such production interruptions could be corrected via instant maintenance and restore work.
However, it is rather expensive to switch 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 really helpful a Lewa triplex course of diaphragm pump for the spray tower software. The drive unit contains a protected start-up mode that retains the diaphragm situated within the neutral place, and steady regulation utilizing an built-in monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it is easy to satisfy the food industry’s stringent hygienic provisions.
a 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 nutritional vitamins, carotenoids, or polyunsaturated fatty acids as active ingredients,” explains Natalie Ibald, plant manager of formulations at DSM Nutritional Products AG. “As part of the method 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 earlier system, the danger of unforeseen interruptions to this process couldn’t be ruled out. As a outcome, the completely different emulsions could not be processed additional. In other phrases, it was not potential to dry them into powder. The pump diaphragm was the explanation: it was usually too delicate to withstand the stress positioned on it when beginning up the pump and would rupture. Replacing เกวัดแรงดันน้ำ lowered the system’s service life and typically meant that trouble-free operation could not be guaranteed.

In the course of searching for a dependable alternative, DSM got in contact with the Swiss subsidiary of pump producer Lewa.
“We were already acquainted with Lewa Nikkiso Switzerland as a supplier of sturdy systems with long service lives within the SFP sector. To ensure trouble-free spray drying, we thought it will be smart to hitch forces with the consultants from Lewa and provide you with a design to unravel the technical issues,” says Ibald.
DSM is dedicated to continually bettering its processes and investing in know-how. This commitment, along with prior expertise with the brief service lives of the previous pumps, led DSM to put special concentrate on dependable operate and a strong design in the course of the challenge planning phase. The list of necessities additionally included a considerable variety of stringent hygienic provisions that needed to be fulfilled.
“Certain foods have provisions relating to microbiological purity which are many occasions extra stringent than these for producing different food merchandise,” explains Ibald. “This meant that the new feed and booster pump needed to meet these more difficult conditions and each kind of contamination had to be dominated out to supply the widest attainable variety of products on the system.”

GUARANTEED SAFE START-UP OPERATION
After a go to at the firm premises to contemplate the spatial and technical parameters, Lewa Nikkiso Switzerland beneficial a type G3F triplex course of diaphragm pump for the spray tower application. This pump contains a fully secure start-up operation, since a spring constantly holds the built-in sandwich diaphragm situated in a impartial position.
This protects the diaphragm against incorrect positioning and prevents it from being damaged while the pump is beginning up, growing system availability considerably. And the Lewa triplex is managed utilizing a pressure reduction valve that’s put in in the hydraulic part and could be configured for the precise 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 long service life and clean common operation for the complete system.
THE POWER OF DESIGN
In addition to the pressure relief valve and the spring control, the design of the diaphragm also plays an necessary function in guaranteeing reliable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which may be extremely long-lasting. They are related to each other through optimistic interlocking through the discharge stroke and mechanical force-fitting through the suction stroke.
This makes the pump hermetically tight and effectively prevents external contamination. As an extra security characteristic, the DPS monitoring system from Lewa continuously screens the situation of the diaphragm. The monitoring unit promptly shows any damage to the device that results in elevated strain within the diaphragm space.
This makes it attainable 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 normally unnecessary to modify the pump off right away, which implies that neither the pumping course of nor spray drying are negatively impacted to a significant extent. If injury to a diaphragm is detected, production can continue with none issues up to a deliberate maintenance 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 process diaphragm pump does extra than just guarantee reliable steady operation. It can be a central component 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 completely clear 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) using completely different alkaline and acidic brokers and with out prior dismantling, it is possible to meet the special requirements for baby food as nicely. The provisions for baby meals are 1,000 times extra stringent than those for different products within the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we had been capable of 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 acquired in June of 2018 and in September of the same year, 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 part of manufacturing at the plant in Sisseln.
“In each part of the venture, Lewa Nikkiso Switzerland demonstrated fast response occasions and well-founded expertise, which made a key contribution to implementing the project efficiently,” says Ibald. “Our specifications with regard to high quality, robustness, and hygiene have been followed to the letter in this venture. As a end result, our production has become noticeably extra efficient and reliable.”
