    the impressive result Important products and technologies have been introduced by this department LEWA triplex process pumps the metering pumps LEWA ecoflow high pressure diaphragm pump heads with PTFE diaphragms and the LEWA CMS Condition Monitoring System To view the its youtube overlay please enable javaScript LEWA Pumpen Systeme Animation force progression Shared development Our team maintains relationships over years with a variety of colleges scientific facilities and many customers We see this early involvement and close collaboration in the development process as an investment in long term customer relationships for mutual success Do you have a special concern Let s think about it together and try out new things We specialize in customer specific development Latest in methods and the latest in equipment In our department we work with the latest in methods and equipment In the past many good products have been developed on a trial and error basis but today we rely on modern simulation processes like FEM Finite Element Methods for analysis of the stress and deformation of parts under high load and CFD computational fluid dynamics for the analysis and subsequent optimization of flows in our products The combination of modern simulation systems with decades of experience in the test field and successful operations in customer systems is the key to successful product development For example one product was developed using FEM simulation that was essentially unique The exact knowledge of the stresses and deformations provided by FEM the comparison with practical experience and some measurements with strain gauge led to a geometry that simply wouldn t have been possible to arrive at on a trial by error basis The animation above shows the clamping point of the diaphragm in the fastening area of a high pressure diaphragm pump head As the pump goes through

    new and further development are the foundation of our position as technology market leader in this sector Variable eccentric With this system already patented in 1974 the stroke length of the pump is set where it originates directly on the crankshaft The system has almost no hysteresis and very low adjustment force since the force transfer is not done via the adjustment elements Through permanent oil bath lubrication and optimum bearing selection an enormous overload safety is achieved The adjustment principle is so successful that with slight modifications in 2003 it is still today the state of the art M5 diaphragm pump head with position control A detailed description of the technology is found here The patent was granted in 1973 and was an important milestone for the development of operationally reliable and universally applicable diaphragm pump heads with plastic diaphragms Due to their well thought out technology they are still installed today with enormous success on LEWA process pumps Sandwich diaphragm with continuous monitoring LEWA diaphragm pumps are frequently used for metering or conveying very hazardous liquids Leaks caused by diaphragm damage are not permissible For this reason LEWA already developed and patented a reliable and simple sandwich diaphragm technology in 1968 The basic principle is so tried and proven that it is still standard equipment today on almost all LEWA diaphragm pumps M9 diaphragm pump head with DPS Diaphragm Protection System A detailed description of the technology is found here The patent for this innovative pump head technology was granted in 2001 parallel to the introduction of the LEWA ecoflow metering pump series As the further development of the M5 technology the M9 pump head is comparatively durable and proven however it has more safety reserves especially when starting up the pump The core of the patented DPS
