General functional descriptions

Progressive cavity pumps VISCOPOWER F 570 & F 580

The progressive cavity pumps VISCOPOWER F 570 & F 580 are positive displacement pumps. Their worm-shaped rotor (eccentric worm) is eccentrically guided in a stator formed as a counterpart. This results in self-contained cavities during the rotation, in which the medium is smoothly and with low pulsation continuously transferred upwards. The suction side is automatically sealed with the eccentric worm. This allows a high pressure build-up, irrespective of the speed of the motor.
