The preparative pump 1521 covers a flow range from 3 to 300 ml/min (max. 200 bar). It operates with serial dual plunger technique with only one suction valve and one pressure valve. The pump heads are made of stainless steel (optinally in PEEK) and come with integrated purge valve.
Control elements like flow rate, minimum and maximum pressure levels can be easily controlled or changed, using the digital switches on the front panel. The LED display shows continuosly the actual back pressure.Error messages and the pressure levels are available through backside connectors for further control purposes
Independent of low or high flow rates and also independent of low or high pressure, the pump will deliver constantly and free of mechanical or electronical disturbances.The electronic speed controller corrects automatically the pressure dependent solvent compressibility. An optinally solenoid valve makes a suction-side, variable sample load of large volumes possible.
For noise reduction, the two-stage driving mechanism (mounted on a solid bottom plate) is completetly isolated from the pump case by an isolation foam plate. Bearings and cam plates are permanently lubricated from an oil reservoir. All components within the pump coming in contact with liquid are placed over a collecting tray equipped with a drain pipe.
