Micropump GAH

Micropump GAH is a high-system-pressure magnetic-drive suction-shoe gear pump for very-low-flow dosing and metering on high-static-pressure process lines. It is relevant for sampling, dosing and metering duties where the pump must handle very low flow while the surrounding system is at high static pressure. Correct specification supports controlled fluid handling, compact integration and more predictable service planning. AxFlow supports product selection and availability.

Key Specifications

  • Flows up to 506 ml/min
  • Pressure up to 5.2 bar

Product features

  • High-system-pressure construction → allows the GA hydraulic platform to operate on systems rated up to 345 bar
  • Very-low-flow suction-shoe design → supports precise pulseless delivery from 8.5 mL/min
  • Verified operating envelope → 8.5–506 mL/min with system pressure up to 345 bar provides a factual basis for initial duty screening
  • Magnetic-drive containment → removes a conventional dynamic shaft seal from the liquid path and reduces a common leakage and wear point
  • Compact pump architecture → supports integration into OEM equipment, analytical instruments and space-constrained process skids
  • Application-specific material selection → lets wetted materials be checked against the actual process liquid before ordering
  • Defined operating limits → checking pressure, temperature, viscosity and suction conditions reduces the risk of incorrect selection
  • Service-oriented construction → supports planned maintenance and replacement of wear components instead of reactive intervention
  • Configuration and drive options → allow the pump and drive arrangement to be matched to the required duty and installation
  • AxFlow selection support → helps confirm the correct series, configuration and service reference before purchase

Product description

Micropump GAH is a high-system-pressure magnetic-drive suction-shoe gear pump for very-low-flow dosing and metering on high-static-pressure process lines. It is intended for engineers, OEM designers and maintenance teams that need predictable fluid handling while controlling leakage risk, process repeatability and service access. Selection should start from the required flow, differential and system pressure, viscosity, temperature, suction conditions and chemical compatibility.

The GAH uses the GA suction-shoe hydraulic platform in a high-system-pressure configuration with magnetic coupling, spur gears, stationary shafts and static sealing. The magnetic coupling transfers torque without a conventional dynamic shaft seal in the liquid path, keeping the motor-side drive physically separated from the process liquid. This removes one common leakage and maintenance point while the hydraulic principle defines flow behaviour, pressure capability and suitability for the duty.

Flow is 8.5–506 mL/min, maximum differential pressure is 5.2 bar and maximum system pressure is 345 bar. The published temperature range is −46 to +177 °C and viscosity range is 0.5–1500 cP. These published values describe the series or cited configuration rather than every possible order code. Final selection must confirm wetted materials, drive speed, connections, suction conditions and any application-specific limits.

For total cost of ownership, correct sizing and material selection are critical. Operating within verified limits supports predictable service intervals and reduces avoidable wear, while planned access to service parts helps maintenance teams control downtime risk. AxFlow can help identify the correct Micropump GAH configuration, check availability and support replacement or OEM projects. Request a quote for Micropump GAH from AxFlow.

Micropump GAH is intended for sampling, dosing and metering duties where the pump must handle very low flow while the surrounding system is at high static pressure. The series should be matched to the actual duty point and liquid properties rather than selected by family name alone. AxFlow can help confirm the correct configuration before ordering.
The magnetic coupling transfers torque without a conventional dynamic shaft seal in the liquid path. This reduces a common leakage and wear point while keeping the drive physically separated from the process liquid. Material compatibility and operating limits still need to be checked for the actual application.
Check required flow, differential and system pressure, viscosity, temperature, suction conditions, wetted materials, connections and drive speed. Also confirm whether abrasives, solids or chemical compatibility introduce additional restrictions. AxFlow can review these points against the available series and configuration data.
Yes, AxFlow can help identify the installed Micropump GAH pump, drive and relevant service parts or replacement reference. Replacement should be based on the full model or order code and application data, not only the series name. This reduces the risk of ordering an incompatible hydraulic or material configuration.
Operate the pump within its verified pressure, temperature, viscosity and suction limits and use wetted materials compatible with the liquid. Planned service and suitable filtration where the application requires it can reduce avoidable wear. Correct sizing and spare-parts planning help maintenance teams reduce unplanned downtime over the equipment lifecycle.
