Description
The HPLC-Pump PN1021 is a dual piston solvent delivery system, which relies on short piston stroke technology and two check valves only. This technology provides the low pulsation of a dual piston pump combined with the reliability of a single piston pump (difficulties in solvent delivery systems are caused mainly by malfunctioning of the valves).
The delivery piston works with a stroke length of 2 mm, the compensation piston with 1 mm. The nearly pulse-less solvent discharge of the PN1021 results from the high stroke frequency/low stroke volume (20 m L) and the use of a compensation piston. While the delivery piston discharges the solvent volume, the compensation piston, located on the pressurized side, collects half of the volume. During the return movement of the delivery piston, the collected volume is discharged from the compensation piston.
The use of a digital speed converter to control speed control leads to a highly stable DC motor operation. As the linearity of the flow range depends on the back pressure of the system, the measured back pressure is used as an additional control element. The pressure is part of the electronic speed control and compensates the reduced solvent flow at high back pressure. This results in a constant flow delivery independent of the back pressure.
All parameters can easily be controlled or changed with the digital switches on the front panel. This facilitates the change of parameters even during operation.
As external control is possible, the pump can easily be integrated into a complete analytical system. Controlling the pump is possible by a start/stop signal (operation parameters have to be pre-selected) or by an analog DC signal (0 - 10 V) to select the flow rate externally.
