Micropump GK

Micropump GK is a Micropump compact cavity-style magnetic-drive gear pump for precision fluid transfer in analytical, chemical, laboratory and OEM systems. It is intended for engineers and OEM builders who need stable fluid handling in compact equipment while controlling leakage risk, repeatability and maintenance access. The correct pump should be selected from the actual flow, pressure, viscosity, temperature and chemical-compatibility requirements.

The product uses a cavity-style magnetic-drive gear arrangement with static O-ring sealing and compact drive-mount options. Magnetic coupling keeps the motor-side drive physically separated from the pumped liquid, while the hydraulic design determines the available flow, pressure capability and tolerance to the process fluid. This architecture supports compact integration and reduces dependence on a rotating shaft seal exposed to the liquid.

AxFlow product data lists capacity up to 12.6 L/min, differential pressure up to 3.4 bar, temperature from −46 to +54 °C and viscosity from 0.5 to 1500 cP. Configuration-specific limits should be confirmed for the installed or replacement pump. These published limits describe the family rather than every possible configuration, so final selection must also confirm wetted materials, suction conditions, drive speed and any application-specific requirements.

For lifecycle cost, correct sizing matters as much as nominal pump capability. A properly selected Micropump unit can support predictable flow, planned service and straightforward spare-parts management, while unsuitable materials or operating conditions can shorten service life. AxFlow can help identify the correct Micropump GK configuration, check availability and support replacement or OEM projects. Request a quote for Micropump GK from AxFlow.
