With the LEWA homogenizer test system, the aseptic operation of a homogenizer based on a hygienic hermetic process diaphragm pump can be tested and flexibly adapted to the requirements of different emulsions thanks to an equally hygienic homogenization valve. (Source: LEWA) Flow rate and pressure required for the homogenization of the process fluid at the two-stage, dynamically controllable homogenization valve are achieved by a LEWA triplex process diaphragm pump. (Source: LEWA) All system components are selected according to hygiene requirements and mounted on a common base frame, making the system particularly suitable for pilot or small batch processes thanks to its compact and space-saving design. (Source: LEWA) The system can be operated both in a circuit and continuously in the customer process. Fluid is supplied either via the heatable vessel or a separate media connection.

(Source: LEWA) Infant formula for newborns contains a special mixture of nutrients and attempts to partially replace the natural supply via breast milk. The industrial manufacturing process is very complex due to the stringent requirements with regard to sterility, often aseptic, and includes the homogenization and spray tower pump.

To be able to flexibly cover this large adjustment range, five LEWA ecodos hygienic pumps are integrated into the system, driven by mechanically actuated multilayered sandwich safety diaphragms (examples of other systems in the image). (Source: BACHEM) To be able to flexibly cover this large adjustment range, five LEWA ecodos hygienic pumps are integrated into the system, driven by mechanically actuated multilayered sandwich safety diaphragms (examples of other systems in the image). (Source: BACHEM) The Swiss technology company Bachem already uses pumps in hygienic design from pump manufacturer LEWA. (Source: BACHEM) Due to the GMP environment, hygienic designs with certified construction materials (FDA, USP) were selected, with all wetted metallic parts electropolished and having a surface roughness of Ra ≤ 0.5 µm.

LEWA ecodos LED3 with PMSM (Source: LEWA GmbH) The PMSMs newly added to the portfolio feature a control range of 1:200, enabling a wider range of applications to be covered by the same drive or pump. (Source: LEWA GmbH) The PMSM also has a constant torque, i.e., the entire torque can be accessed at 0 rpm. This ensures a particularly smooth and gentle start-up of the system, as each process can be initiated with a conveyance rate of 1 percent instead of the usual 10 percent. (Example: Metering omega-3 fatty acids in the production of baby food) (Source: Adobe Stock) The constant torque of the PMSM allows for continuous operation at low speeds, unlike the depicted ASM. Oversizing for the required starting torque of the pump has become unnecessary due to the high overload capacity of the PMSM. (Source: LEWA GmbH) In contrast to the ASMs shown, the constant torque of the PMSM enables continuous operation at low speeds. Oversizing for the required pump starting torque has become unnecessary due to the high overload capability of the PMSM. (Source: LEWA GmbH) Like the asynchronous motor, the PMSM can be controlled via a standard frequency converter (NORD, Danfoss, etc.) with special parameterization, so that users can rely on common parts. (Source: Getriebebau NORD GmbH & Co. KG) Decentralized solutions in which the frequency converter is installed directly on the PMSM are also already possible with the PMSMs selected by LEWA. (Source: Getriebebau NORD GmbH & Co. KG) Decentralized solutions in which the frequency converter is installed directly on the PMSM are also already possible with the PMSMs selected by LEWA. (Source: Getriebebau NORD GmbH & Co. KG) Already in 2020, LEWA conducted initial functional tests with the NORD PMSM prototype and an ecodos pump on the pump test stand. Especially in the lower speed range, the PMSM successfully demonstrated the advantages of constant torque: the ecodos test pump could be operated in a range of 1:480 up to 5 bar. (Source: LEWA GmbH)

In order for vaccines to be produced reliably and in sufficient quantities, depending on the production method, the appropriate technical equipment, such as hygienic and high-precision pumps, is required. (Source: Gerd Altmann, pixabay) To avoid mixing errors, the pumps were designed in the triplex variant, i.e., with three pump heads per pump and motor. This meant that a pulsation damper was not necessary.

The chemical injection package for pumping sodium hypochlorite solution was delivered by LEWA NIKKISO Middle East to Zirku Island in the United Arab Emirates. It was part of an order that included a total of 13 injection packages. (Source: LEWA NIKKISO Middle East FZE) The two-compartment sodium hypochlorite tank was made of fiberglass-reinforced plastic (FRP). All other wetted parts were made from corrosion-resistant titanium material. This material is especially well-suited for the pumped fluid at the design temperature of 85 °C. (Source: LEWA NIKKISO Middle East FZE) The material for the piping is titanium (Grade 2); a total of 58 meters of pipe with diameters from ½ to 2 inches. A total of 339 welds have been completed. To meet the high standards for weld quality, LEWA NIKKISO Middle East built its own cleanroom. (Source: LEWA NIKKISO Middle East FZE) During welding, an auxiliary welder held the shield diffuser, ensuring optimal coverage of the heat-affected areas with pure argon gas.
