LEWA diaphragm metering pumps are reciprocating positive displacement pumps that offer high metering accuracy and are the standard for safety and hermetical tightness, especially when conveying critical fluids. A diaphragm separates the fluid conveyed from the drive unit. LEWA’s principle of construction assures that the diaphragm always moves in the optimum working range. To maintain the lowest stress possible on the diaphragm it is hydraulically actuated in these LEWA metering pumps which, in connection with the diaphragm Protection System (DPS), guarantees an extremely long diaphragm service life combined with an easy start-up even under adverse suction conditions.

•		Flow rates up to 68 l/h per pump head
•		Discharge pressures up to 560bar
•		Micro-metering pumps with hydraulically actuated metal diaphragm of the LEWA Micro-Flow Metering Pumps series are precise, reliable, leakage- and maintenance-free
•		They are mainly used in the laboratory and for process development in pilot plants; integrated or separate controls are available
•		The pumps have very pressure stiff characteristics, this means that the system pressure has little influence on the flow rate
