7800 Digital Dosing Pump
Brand: Burkert Fluid Control Systems
The Type 7800 digital dosing pump is characterised by a drive principle that is completely new for dosing pumps. The drive is carried out by a microprocessor-controlled stepper motor, which is connected directly to the diaphragm by a crankshaft-and-connecting-rod drive.
This means that, in contrast to conventional dosing pumps, the position and the speed of the diaphragm is controlled by the microprocessor electronics during the complete discharge/ suction cycle. The microprocessor-controlled compression stroke results in a dosage that is considerably more even, particularly with small dosages.
The 7800 dosing pump always works with the maximum stroke length, whereby a high accuracy for the dosing over the full setting range and a lower sensitivity with respect to gaseous media is achieved.
Through an optimised clearance volume ratio with the full stroke length, the accuracy and function is ensured, even for difficult degassing liquids. Through the anticavitation function, the drive is optimally adapted to the dosing of high viscosity liquids.
Features- Continuous dosing through digitally controlled stepper motor drive
- Limitation of the max. dosage through software
- Setting range for the dosage 1:1000
- High accuracy over the complete setting range
