LEWA micro-metering pumps — Advantages LEWA diaphragm pumps for the smallest metered flows. The advantages at a glance. 1 High pressure levels The micro-metering pumps can be used at pressure levels up to 8,120 psig. This is made possible by the hydraulic actuation of the diaphragm pump heads. Leak-proof and reliable The pump is hermetically sealed by the diaphragm's static seal, making it incredibly reliable. The metal diaphragm is absolutely impervious to leaks caused by diffusion, completely eliminating the chance of leaks from pumped fluid or hydraulic oil. Precise Drive units free of backlash...
