LEWA intellidrive®: Specialized Kinematic Diaphragm Metering Pump for Chromatography
Metering pumps for special fluid kinematics.
The LEWA intellidrive® metering pump is the pinnacle of innovation for special kinematic applications, such as high-precision chromatography in the pharmaceutical sector. This advanced technology, featuring a dynamic servomotor, provides infinitely variable stroke times, enabling the customization of pumping characteristics to meet the specific kinematic needs of your system and process.
Its intelligent motion control excels in metering highly viscous fluids and executing precise, small-volume dosing across extensive control ranges. When paired with a secondary pump, the intellidrive technology ensures near-pulsation-free volume flows through meticulous synchronization.
Available in both LEWA ecoflow and ecodos models, the intellidrive® system adapts to special metering requirements, offering unparalleled precision and control for chromatography processes and other applications where exact fluid kinetics are crucial."
Key Advantages of LEWA intellidrive®: Special Kinematics Metering Pump for Chromatography
LEWA intellidrive pumps stand out as mechatronic diaphragm metering pumps equipped with special intelligent drive technology, tailored for precise kinematics in chromatography applications. The innovative servomotor drive offers numerous advantages over conventional drive technologies, enhancing metering accuracy and reliability.
Fluids with high viscosities
Through the decelerated suction stroke, the LEWA intellidrive is very well suited for fluids with high viscosities up to 100.000 mPa∙s e.g. honey. This characteristic makes LEWA intellidrive unique in comparison to other pumps.
Easy integration into higher-level process control systems
Interfaces such as Ethernet and Profibus ensure problem-free system integration. Pumps can be integrated as field equipment in the higher-level process control technology. Prefabricated plugs on the pump motor connect the supply and signal lines with the control unit. Analog inputs and outputs, for example for valve control, can be expanded.
Large adjustment range
Precision is our strength: The drive of the LEWA intellidrive metering pump can be configured in an extremely large control range of at least 1:150. This allows us to fulfill the most stringent requirements for sensitive metering tasks, for example in the pharmaceutical industry.
Individual suction and discharge stroke characteristics
The LEWA intellidrive technology can be used to model, program and save individual suction and discharge stroke characteristics. Using various suction and discharge stroke frequencies, high-viscosity fluids are drawn in slowly and with low pressure loss via the smaller valve nominal width – and then quickly fed to the process in the discharge stroke.
Synchronization of pumps for pulsation reduction
By using two synchronized intellidrive pumps, a virtually pulsation-free volume flow can be generated. Therefore, the piping system, in some cases, can make do without pulsation dampers. These are often hard to clean, particularly in hygienic applications.
Precise filling tasks and fluid chromatography
Infinitely variable stroke times permit fluids with special kinematics to be moved successfully. This makes it terrifically well suited as a metering pump in filling tasks or in highly precise chromatography systems in the pharmaceutical area.
Suitable for the smallest flow rates
The LEWA intellidrive implements extremely small flow rates up to 1 ml/h with precision. No other industrial pump reaches the degree of precision often required in pharmaceutical and biotechnological processes.
API 675 standard
The intellidrive series fulfills the internationally valid quality standard of the American Petroleum Institute API 675. In this standard, all requirements for a displacement pump in industrial settings are defined with respect to design, construction and performance. We would be happy to present you with further certifications, if desired.
LEWA Smart Monitoring
With digital pumps for more efficiency, system availability and profitability of the entire production.
LEWA Smart Monitoring is a monitoring system consisting of sensors, a programmable logic controller (PLC), an industrial PC (IPC) and data analysis for new and existing pumps. The system determines characteristic values and key performance indicators. There is no intervention in process control or direct contact between the sensor system and the conveyed fluid.
With key performance indicator-based condition monitoring, you detect and monitor operating statuses proactively. You can also optimize the overall output and robustness of your pump and pipe systems. This will increase the efficiency of your entire production plant. You can access the data conveniently via your corporate network. Or you use the LEWA cloud with extended analysis and service offers.
