Continuous metering of abrasive materials
The progressive cavity pump is a high-precision volumetric metering system that operates continuously and pulsation-free. The rotational motion of the eccentric screw ensures highly precise, constant metering, particularly in the case of small output rates from 0.1 ml/min. The special rotorstator combination prevents excessive wear when processing abrasive materials. This guarantees a long service life and high cost-efficiency.
Thanks to eccentric screw pump technology, liquids and pastes with up to 60% filler content can be metered with high precision. The metering quantity can be adjusted completely linearly. This enables a metering precision of ± 1% and better.
