Progressing Cavity Pumps

Allweiler GmbH’s OptiFix is a pump designed for wastewater treatment applications. It can be disassembled in five steps, eliminating the need to dismantle it from piping to change the rotor, stator, joints, or shaft seal. It has a leak-resistant ATLS-T1V sensor to detect dry-running conditions before they do damage, as well as a zero-play stub shaft connection and optimized heat transition from the stator elastomer to the sensor sleeve. It is available in multiple rotor-stator geometry choices and sizes for application-specific configurations to accommodate needs for low flow velocity, volumetric efficiency, gentle conveyance of compacted products or large suspended solids, and a compact footprint.
