Single piston pump with flow rate 0.01–9.99 ml/min and limit of pressure 40(20) MPa is suited for columns washing and columns regeneration process of chromatographic columns in liquid chromatography. It is designed with piston diameter of 1/8”.
This pump may be used in classical analytical applications where pulsation does not matter (is not possible to use with RI detectors). Pulsation should be eliminated by pulse dampers. More then one pumps controlled by ECOMAC can produce high-pressure gradient.
Quite new concept of electronic and pump drive allow using it as standalone unit, just as in PC controlled systems.
New piston suspensions and its easy replacement prolong working life and simplify maintenance.
Intuitive operating using simple keypad allows easy functions chosen:
LED display allows to watch (also from a distance) actual pressure or flow-rate settings.
By work with buffered solvents is possible to use pistons back washing.
