The pump has two pistons connected in parallel, with a diameter 3/8”. It is suited for preparative liquid chromatography, where high pressure is needed, etc. The advantage of this pump is a very stable run even at low flow rates. Also available in configurations made of certified bio-inert materials.
This pump is designed as a standalone unit.
There is a possibility to use this pump in a high-pressure gradient mode, where two, three, or four units are controlled via PC using RS232.
The control board is mounted on the unit's backside therefore the installation is very easy. Just connect the power voltage and RS232 and the pump is ready to go.
When working with buffered solvents, it is possible to use pistons backwashing.
The pump is supported by the software ECOMAC and Clarity.
This pump does not have a pressure sensor.
This pump is equipped with the Pressure Compensation Learning algorithm. Thanks to this smart adaptive process, the pump regulates the rotation speed of the camshaft and measures its impact on pressure pulsation to minimize the output pulsation as much as possible. The algorithm, due to its adaptive capacity, is applicable for many combinations of pump working conditions (solvents, columns, etc.).
