Let us help you find the right product from this series
Key Specifications
- Flows up to 6.8 l/min
- Pressure up to 5.5 bar
Product features
- Cavity-style reversible gear design → supports intermittent reverse pumping as well as forward transfer
- Smooth pulseless delivery → supports stable dosing, metering and analytical fluid handling
- Verified operating envelope → 158 mL/min–6.8 L/min and differential pressure up to 5.5 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
Micropump GJ is a cavity-style magnetic-drive gear pump for high-precision dosing, metering, reversible transfer and circulation. 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 GJ uses a compact cavity-style positive-displacement gear set with two helical shafted gears, sleeve bushings, PTFE gaskets and seals, and magnetic coupling. 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 158 mL/min–6.8 L/min, maximum differential pressure is 5.5 bar and maximum system pressure is 21 bar. The published temperature range is −46 to +121 °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.
