Key specifications

  • Flows up to 3700 l/h
  • Pressure up to 350 bar

Key product features

  • Hydraulic double-diaphragm principle -> Combines high-pressure dosing with an additional containment barrier
  • Double diaphragm construction -> Adds protection where process leakage must be avoided
  • Rupture detection -> Helps operators respond to diaphragm damage before the risk escalates
  • SMART DIAPHRAGM hydraulic management -> Supports stable hydraulic balance and diaphragm operation
  • Adjustable stroke -> Allows capacity to be matched to the required dosing rate
  • Wetted-material options -> Helps match the pump to chemical compatibility requirements
  • API 675 capability -> Supports specification for demanding metering-pump projects
  • ATEX configurations where available -> Supports selection for appropriately classified installations
  • 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

Product Description

OBL Topline X9 is an OBL hydraulic double-diaphragm metering pump for continuous chemical, oil and gas and demanding industrial dosing where leakage control and high pressure matter. It is intended for professional dosing duties where repeatability, chemical compatibility and predictable maintenance influence process reliability. Request a quote for OBL Topline X9 from AxFlow.

The series uses a hydraulic double-diaphragm metering pump principle. Key construction and performance details include double diaphragm construction, visual rupture detection, SMART DIAPHRAGM hydraulic management, flow up to 3,700 l/h, pressure up to 350 bar and temperature up to 280 °C; API 675 and ATEX options are available. 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.

Sales Brochure

OBL Topline X9 is used for continuous chemical, oil and gas and demanding industrial dosing where leakage control and high pressure matter. Its hydraulic double-diaphragm 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 hydraulic double-diaphragm metering pump design, with technical details including double diaphragm construction, visual rupture detection, SMART DIAPHRAGM hydraulic management, flow up to 3,700 l/h, pressure up to 350 bar and temperature up to 280 °C; API 675 and ATEX options are available. 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.
