NOV Mono Low Flow Metering Pump LWD

NOV Mono Low Flow Metering Pump LWD is intended for accurate low-flow dosing of process liquids and chemicals. 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 deliver smooth, repeatable flow at low capacities. Its construction is based on a compact progressing-cavity metering element with material options selected for the liquid, 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 0.63 m³/h and a maximum pressure of 24 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.
