Pneumatic high-pressure pump


with 250 ml pump head (stainless steel), for max. 200 bar

The Smartline Pneumatic Pump 1950, powered by compressed air, has been designed for solvent delivery in process chemistry, column packing or preparative chromatography. Application areas:

  • packing of HPLC columns at pressures up to 200 bar
  • metering against constant pressure

The delivery flow rate depends on the compressed air supply and the back pressure of the column or system. Maximum delivery flow rate can be reached at minimum liquid pressure (below 1 bar). The minimum liquid flow rate (approx. 5 ml/min) is achieved at highest back pressure. The Smartline Pneumatic Pump 1950 (A50761) has a 250 ml stainless steel pump head and can be operated at maximal 200 bar back pressure for solvent delivery.
