About Process-Diaphragm Pumps

The LEWA process diaphragm pumps for high pressure process engineering are the standard for tightness in the high pressure range. Here also LEWA has set the standards and consistently further develops the diaphragm pump technology. With LEWA process diaphragm pumps even critical, toxic or inflammable fluids can be conveyed safely. Also extremely low viscosity, non-lubricating fluids or abrasive suspensions are handled without any problems. The pressure range goes up to 1200 bar.
