American Lewa - Metering Pumps, Process Diaphragm Pumps and Packaged Systems

LEWA is a global producer and supplier of metering pumps, process diaphragm pumps and packaged systems.

LEWA pumps and packages are used in many industries and almost all markets in the world including the chemical, oil and gas e.g.for low to high pressure chemical injection, intermittent or continuous high pressure methanol/ethanol injection, solar-, electric motor - ,gas/air driven chemical injection packages, H2 S/CO2 re-injection, condensate forwarding and re-injection, glycol injection and many other applications.

METERING PUMPS

LEWA metering pumps convey and develop pressure, and measure and provide infinitely adjustable fluid flow by varying stroke length and/or speed.

• Simplex and multiplex pumps of modular design for universal use
• Standard metering pumps for the low pressure range
• Precision metering pumps for micro metering

LEWAecoflow®: the world's broadest and most flexible line of heavy-duty building block pump components combine to meet your application requirements. Ideal for maximum flexibility and the possibility of future expansions. Especially useful in the precise setting of formulations and recipe blending applications, widely varying flow rates and large turndowns to 100:1 by both stroke length and speed. Drive elements have a built-in worm gear, which eliminates the need for bulky external gearboxes.

LEWAtriplex®: the modern approach to seal-less high pressure pumps with double containment and a unique monoblock drive element. Produced for traditional power pump services where safety, leak-free operation, low maintenance and maximum reliability are required. Their footprint is extremely compact and with an integral worm gear and vertical flange-mounted motor, no base plate is needed.

LEWAecodos®: a standard range of diaphragm metering pumps offering the ideal balance of safety, performance and value.

PROCESS DIAPHRAGM PUMPS

LEWA produces hermetically sealed process diaphragm pumps for high flowrates at high pressure, offering double safety through a sandwich diaphragm. Available in space-saving monoblock or variable modular designs.

• Leakage-free LEWA process diaphragm pumps for high flow rates are the standard for tightness in the high pressure range - the fluid conveyed is sealed from the atmosphere
• LEWAtriplex space-saving monoblock design and LEWAecoflow in a variable in-line construction assure zero-leakage, low-maintenance operation
• Proven high pressure diaphragm pump heads with metal or PTFE sandwich diaphragms guarantee high availability of the pumps
• A special feature of both LEWAtriplex and LEWAmodular is the high overall efficiency and low life-cycle costs
• Unlimited dry-running capability: the pumps are robust even in technical borderline cases and, because of their pressure firm characteristics, convey fluids very precisely even when the pressure fluctuates

PACKAGED SYSTEMS

LEWA provides solutions for metering and mixing applications from engineering to on-site commissioning through:

• Standard metering packages
• Metering packages designed for specific applications
• LEWA metering systems
• LEWA odourizing systems

LEWA packages are complete, pre-tested, ready to use assemblies for metering, proportioning, injection or continuous recipe blending and mixing.

The controlled addition of fluids in conjunction with other process steps plays an important role in many production plants relying on process technology. The trend towards increased automation for better plant control, reduced recipe volumes and fast recipe changes requires modern process displays, recording of operating data and interfacing with central process management systems.

LEWA has the experience, know-how and project management skills to meet your specific package requirements:

• Basic up-front engineering, including verification of the process steps required
• The best components to meet your design goals and plant standards
• Optimized layout of pumps, piping, accessories, instrumentation and controls
• Construction inhouse or by experienced fabricators using modern techniques
• Testing and certification of manufactured components to industry standards
• Installation assistance, start-up and service available worldwide

INDUSTRY APPLICATION AREAS

LEWA pumps and packages are used in many industries and almost all markets in the world including the chemical, oil and gas, pharmaceutical and life science industries. Other markets include food and beverages, pulp and paper, plastics, semiconductors and solar power.
