Pneumatic high-pressure pump

with 100 ml pump head (stainless steel) for max. 1000 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 1000 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 (A50751) has a 100 ml stainless steel pump head and can be operated at maximal 1000 bar back pressure for solvent delivery.
