OBL MD

OBL MD is used for controlled dosing where diaphragm containment and straightforward handling are important. The series is relevant where chemical dosing accuracy, process containment and predictable operation affect product quality, safety or production continuity. It is supplied by AxFlow for professional users who need a technically matched metering pump rather than a generic transfer pump.

The pump is based on a mechanical diaphragm metering pump construction. Key construction details include spring return mechanism, eccentric shaft and thrust ring with diaphragm containment. These characteristics help the pump handle controlled dosing tasks while keeping the relationship between pump technology, medium properties and installation requirements clear during selection.

For selection, engineers should check the required flow, differential pressure, temperature, chemical compatibility, viscosity, control method and installation arrangement. Where actuator options, rupture detection, multiple heads or material alternatives are available, they should be matched to the process risk and maintenance strategy before ordering.

AxFlow supports product selection, availability checks, service planning and spare parts identification for OBL metering pumps. Correct pump configuration helps reduce dosing instability, avoid unnecessary maintenance interventions and protect process continuity, supporting a lower total cost of ownership over the operating life.
