Diaphragm Pumps work in process chromatography.

Press Release Summary:




Sealless Hygienic Diaphragm Pumps are hermetically tight, have no moving shafts or dynamic seals, and provide low pump head volume. They handle flow rates to 6 gal/min and 280 psig per pump head at ±1% accuracy. Wide turn-down range is achievable by stroke or speed adjustment. Industrial, sanitary, and ASME BPE-1997 compliant hygienic models are available to meet upstream or downstream process, pressure, and CIP/SIP requirements.

Hygienic Diaphragm Pumps For Process Chromatography Applications



A full line of sealless diaphragm pumps for applications that require high metering accuracy and repeatability, a wide turn-down range, and the gentle handling of shear-sensitive fluids is available from AMERICAN LEWA, Inc. of Holliston, Massachusetts.

LEWA Hygienic Diaphragm Pumps are hermetically tight, have no moving shafts or dynamic seals, and provide low pump head volume; making them ideal for a variety of process chromatography applications. Featuring a wide turn-down range, achievable by stroke or speed adjustment, they are offered in industrial, sanitary, and ASME BPE-1997 compliant hygienic models to meet a full range of up- or downstream process, pressure, and CIP/SIP requirements.

Available configurations of LEWA Hygienic Diaphragm Pumps include the Ecodos Series which handles flow rates to 6 gal/min and 280 psig per pump head at ±1% accuracy, with the ability to multiplex up to six pump heads, and modular pumps for flow rates from mls/hour to thousands of gallons per pump head and pressures up to 17,500 psig at >±l% accuracy. Highly precise gradient chromatography can be accomplished by using stepping motors.

LEWA Hygienic Diaphragm Pumps are priced from $1,500. up, depending upon configuration.
