Mini and micro dispensing solutions for fluids and pastes

ASYMTEK Dosing technology is based on the endless dosing progressing cavity pump. The
rotating element “Rotor” and the static counter part “Stator” form an optimal chamber
“Cavity”. Both rotor and stator touch eachother over the whole length to create a continuous
seal that prevents backflow even with higher back pressure. The movement of the rotating
rotor in the stator allows the fluid to be gently pushed to the next chamber without shearing
and squeezing the fluid. (picture 1).
Due to the fact that the cavity along the sealing line is always open, particles can be handled
without difficulties. ASYMTEK technology will pump and dose abrasive fluids but also more
viscous pastes whenever the chambers are correctly and completely filled.
ASYMTEK Rotors are manufactured to resist many chemical materials according CE
conformity. The high degree of smoothness of the rotor surface prevents fast wear and tear
and provides long life cycle time.
ASYMTEK Stators have been developed to offer less friction.
Driving the pump counter clockwise CCW conveys the fluid or paste from the suction side
towards the pressure side in picture 1 from left to right. To empty vessels or bottles, in
general the flow should go from right to left meaning clockwise CW. ASYMTEK pumps can
be used in continuous or indexed applications.
Picture1:
Shows the possibility to convey
particles and a gentle flow of the
material (yellow).
The dosing volume is
independent of the rotor(blue)
position since the cavities have a
defined volume.
Therefore, PCP technology is
optimal for dispensing.
Avoid dry running! Do not test with water!
