LEWA micro-metering pumps — Introduction

LEWA micro-metering pumps — Introduction LEWA offers a comprehensive line of micro-metering pumps with diaphragm technology for metering fluids in laboratories and test centers. This includes solenoid-driven diaphragm metering pumps covering an extensive range of applications with seven different solenoid power sizes. In addition, we offer a pump plus control system installed in a space-saving housing for your laboratory bench. The innovative LEWA intellilab is a high-pressure micro-metering pump with integrated drive and control technology. The motorized FC micro-metering pumps put the...

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...
