The LEWA intellidrive technology can be used to design the pump’s suction and discharge stroke and individually model the pumping characteristics!
The highly dynamic servomotor modulates the pump’s stroke according to the demands of your system and process. The stroke adjustment normally required for metering pumps can then be omitted. The LEWA intellidrive diaphragm metering pumps implement flow volumes up to 4 m³/h and discharge pressures up to 1000 bar.
Metering pumps for special fluid kinematics.
Fluids with special kinematics are pumped in many filling tasks and high-precision omatography processes in the pharmaceutical industry. LEWA has developed the intellidrive technology for this purpose. The highly dynamic servomotor makes it possible to regulate the pump’s stroke times in an infinitely variable manner, thus modeling individual pumping characteristics according to the demands of your system and process.
This intelligent motion control also enables the metering of highly viscous fluids and facilitates metering of very small volumes, even over very wide control ranges. In combination with a second pump, nearly pulsation-free volume flows can be generated through accurate synonization.
Intellidrive technology is available as either a LEWA ecoflow diaphragm metering pump or ecodos diaphragm metering pump.
Good reasons for a LEWA intellidrive®
LEWA intellidrive pumps are mechatronic diaphragm metering pumps with intelligent drive technology via servomotor. The innovative servomotor drive features various advantages compared to other drive technologies.
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 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.
Synonization of pumps for pulsation reduction
By using two synonized intellidrive pumps, a virtually pulsation-free volume flow can be generated. Therefore, the piping system, in some cases, can do without pulsation dampers. These are often hard to clean, particularly in hygienic applications.
Precise filling tasks and fluid omatography
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 omatography 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.
