LEWA intellidrive diaphragm metering pump

LEWA intellidrive®
diaphragm metering pump

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.

LEWA intellidrive® diaphragm metering pumps

Metering pumps for special fluid kinematics.

Fluids with special kinematics are pumped in many filling tasks and high-precision chromatography processes in the pharmaceutical industry. We developed the LEWA 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 synchronization.

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.

Pumps for metering of highly viscous fluids

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.

Integrated control rule systems

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.

Pumps with a wide dynamic range

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.

Suction, discharge, stroke

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.

Pulsation reduction

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.

    Customized valves

    LEWA uses numerous special types of valves such as specially hardened valves for liquified gases or valves with minimal dead space for the food and pharmaceutical production.

    Diverse connection geometries

    Our pumps are equipped with all common connection geometries such as DIN standard, BASF's high-pressure standard, American ANSI, JIS, or your individual requirements. Customized configurations are possible.

    Heating and cooling jacket

    With heating and cooling jackets, our pumps are suitable for almost any temperature and can convey fluids at low temperatures or extreme heat.

    Special design materials

    If the process demands it, wetted parts such as pumps heads and valves will be made of special materials such as stainless steel 316/316L (1.4401/1.4404), Hastelloy or Duplex steel and PVC.

    Diagnostic connection

    Our pumps and systems have connections that facilitate the diagnosis of their performance. This is done by a service technician on site or via remote monitoring.

    Integrated pressure relief valve

    An integrated pressure relief valve prevents potential overload situations. The valve is individually adjustable and can be adapted to different operating situations.

    Sanitary & hygienic design

    LEWA pumps and systems in sanitary & hygienic design are available for applications that require extremely high purity, such as food production and the pharmaceutical industry.


    CIP and SIP capability

    Many LEWA pumps, systems and units can be cleaned (Cleaning in Place) and sterilized (Sterilization in Place). To carry this out, it is not necessary to disassemble the equipment.

    Complete documentation

    In the process of documentation, we consider your requirements and provide inspection records, print samples, diagrams of output characteristics and registration papers on request.
