Why We Use Membrane Pumps

Our extractors don’t use piston pumps or compressors, we use diaphragm metering pumps only.

Although the cost is higher compared to a simple gas booster or piston pump, the advantages are considerable. In fact, diaphragm metering pumps are not affected by supercritical fluid because process fluids are completely separated from the mechanical part of the pump. Diaphragm metering pumps meet the highest requirements and demands of the chemistry, cosmetics, pharmaceutical and biotechnology industries, or food and beverage industries. Some of most important advantages are:

  • High energy-efficiency ratio
  • Low maintenance costs
  • Extremely long service life for diaphragms
