Product Description

OBL RH is an OBL plunger metering pump for heavy-duty chemical, petrochemical and power-generation dosing. It is intended for professional dosing duties where repeatability, chemical compatibility and predictable maintenance influence process reliability. Request a quote for OBL RH from AxFlow.

The series uses a plunger metering pump principle. Key construction and performance details include cast-iron drive housing, vertical construction, flow up to 620 l/h, pressure up to 40 bar and temperature up to 45 °C. This gives engineers a defined technical basis for matching the pump to flow, pressure, medium and installation conditions.

During selection, check required capacity, differential pressure, liquid temperature, viscosity, chemical compatibility, control method and connection arrangement. Materials, diaphragm or packing configuration, actuators and multi-head options should be selected for the actual process duty rather than assumed to suit every installation.

AxFlow can support OBL pump selection, availability checks, service planning and spare-parts identification. Correct configuration helps maintain dosing stability, reduce avoidable interventions and protect process continuity. This supports more predictable maintenance and lifecycle cost over the operating period.

OBL RH is used for heavy-duty chemical, petrochemical and power-generation dosing. Its plunger metering pump construction is intended for controlled metering rather than general liquid transfer. The exact configuration should be matched to the medium, duty point and installation.
Check required flow, differential pressure, temperature, viscosity and chemical compatibility. Also review the required control method, connections and wetted materials. AxFlow can help compare these requirements with available OBL configurations.
The series is based on a plunger metering pump design, with technical details including cast-iron drive housing, vertical construction, flow up to 620 l/h, pressure up to 40 bar and temperature up to 45 °C. These values describe series limits or available configurations rather than one universal operating point. Final selection must therefore be made against the actual process conditions.
Maintenance should follow the OBL instructions for the selected pump configuration and operating conditions. Wear parts, diaphragms, packings, valves and drive components should be inspected according to the actual duty. Planned service and correct spare-parts identification help reduce unplanned downtime.
Yes. AxFlow can support duty review, product selection, availability checks and identification of service and spare parts. The final pump should be selected against the actual chemical, pressure, flow and installation requirements. Contact AxFlow for technical support and a quote.
