The preparative HPLC pump 1521 works in a delivery range from 3 – 300 ml /min at working pressures up to 200 bar. The solvent delivery happens via a serial 2 piston arrangement (Modell 1511 with one piston only) with an inlet and an outlet valve. The pump heads are made of stainless steel, PEEK or titanium with an intergrated prime/purge valve.

The settings of flow rate, minimum and maximum pressure limits are done via a digital switch. The current back pressure is permanently shown via a LED display. Computer optimised cam shaft with integrated precondensing decreases the pulsation which allows a good pressure profile even at flow rates of 3ml/min. Error messages and pressure profiles are fitted to a higher control unit.
