LEWA ecosmart®: The clever idea for plant engineering

When discharging or metering fluids, industrial system operators must often observe rigid safety and environment aspects and meet the requirements of individual processes. With LEWA ecosmart a diaphragm metering pump for intermediate requirements has been delevoped: This series offers the best price more

• VACUU•LAN® Vacuum Local Area Networks
  

  In modern chemical and pharmaceutical lab buildings vacuum supply has become a standard for each work station, just as water or gas supply. Therefore vacuum supply solutions are considered at earliest stage for new laboratory buildings and are fully integrated in the planning and layouting procedure in many cases. Demands for vacuum vary over a wide range of applications – e.g. evaporation, distillation, vacuum drying, or simply filtration and aspiration. All of these can be covered well by Chemistry Diaphragm Pumps more

• Sensors, Vol. 12, Pages 13075-13087: Electromagnetically-Actuated Reciprocating Pump for High-Flow-Rate Microfluidic Applications

  This study presents an electromagnetically-actuated reciprocating pump for high-flow-rate microfluidic applications. The pump comprises four major components, namely a lower glass plate containing a copper microcoil, a middle PMMA plate incorporating a PDMS diaphragm with a surface-mounted magnet, u more

• Microspheres as Resistive Elements in a Check Valve for Low Pressure and Low Flow Rate Conditions

  n this paper we describe a microsphere-based check valve integrated with a micropump. The check valve uses Ø20 μm polystyrene microspheres to rectify flow in low pressure and low flow rate applications (Re<1). The microspheres form a porous media in the check valve increasing fluidic resistance base more

• A study on high-output piezoelectric micropumps for application in DMFC

  In order to supply liquid fuel in DMFC (Direct Methanol Fuel Cell) system, a small but high-output micropump is needed. This study presents a design concept, fabrication and experimental results of the newly devised piezoelectric micropump by using resonance and fluid inertia. The micropump consists more
