Precision Pumping with Quantex Single-Use Pumps
The Quantex pump technology is founded on the principle of a fixed displacement rotary action – fixed displacement delivers high volumetric accuracy and the rotary action means there is no limit to volumes that can be dispensed. Fixed displacement is the result of the volume of an individual bolus carried on the rigid rotor constrained within the rigid pump housing.
The pump design principal ensures that a precise volume of liquid is displaced for each revolution over a wide range of flowrates, pressures, viscosities and temperatures. No motor software compensation is required, and the dispenser essentially comprises of a motor, motor controller and power supply. Typically, stepper motors are used or DC motors with encoders to control speed of rotation (flowrate) and number of rotations (dose volume). The rotor may carry 5 cavities and run at up to 10rps so the pump is operating at 50Hz. Thus, very high resolution can be achieved even at high flow rates. Also, the amplitude of pulsation is reduced compared to larger stroke pump types.
Pump performance data can be reviewed in the respective brochures in the pump catalogue pages.
