Product features
- Hydraulic diaphragm principle -> Combines process containment with higher-pressure dosing capability
- Seal-less product containment -> Reduces leakage risk in demanding chemical duties
- Hydraulic balance control -> Supports stable diaphragm operation across the dosing cycle
- Integrated protection functions -> Helps protect the diaphragm and hydraulic circuit where fitted
- Adjustable stroke -> Allows capacity to be matched to the required dosing rate
- Wetted-material options -> Helps match the pump to chemical compatibility requirements
- Single or multiple-head configurations -> Supports complex dosing arrangements where available
- Serviceable diaphragm and valves -> Supports planned maintenance and spare-parts replacement
- AxFlow selection support -> Helps match duty point, materials and installation requirements
- AxFlow service and spare-parts support -> Helps reduce downtime risk over the pump lifecycle
OBL XLB is an OBL hydraulic diaphragm metering pump for demanding multi-head process dosing where leakage prevention and independent adjustment are required. It is intended for professional dosing duties where repeatability, chemical compatibility and predictable maintenance influence process reliability. Request a quote for OBL XLB from AxFlow.
The series uses a hydraulic diaphragm metering pump principle. Key construction and performance details include up to five heads, independent manual adjustment, AISI 316L wetted parts, double diaphragm, visual rupture detection and API 675 conformity. 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.
