Mono Widethroat W121

Mono Widethroat W121 is intended for viscous, non-flowing and solids-rich media that require positive feed into the pumping element. It is relevant where the process needs a positive-displacement pump matched to a defined duty point and where reliable transfer directly affects process continuity, downstream equipment and maintenance planning. The model is built to improve product entry and reduce feed interruptions in difficult transfer duties. Its construction is based on a large inlet, auger/screw feed and progressing-cavity pumping element, so the operating speed, rotor/stator geometry and selected elastomer or wetted materials can be matched to the medium and installation requirements. The supplied model data lists a maximum capacity of 86 m³/h and a maximum pressure of 6 bar. These are selection limits rather than a guarantee for every liquid, speed or material combination; viscosity, solids, temperature, suction conditions and compatibility still need to be checked. For lifecycle cost, the key considerations are wear-part condition, rotor and stator selection, seals, drive condition and access for planned maintenance. AxFlow can support model identification, spare-parts selection, service and replacement assessment so maintenance teams can reduce unplanned downtime and keep the installed pump aligned with the process duty.
