Micropump Dual-Circuit 84888

Micropump Dual-Circuit 84888 is a Micropump dual-circuit magnetic-drive gear pump assembly for service and replacement of Domino A-Series continuous inkjet printer fluid circuits. 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 GA suction-shoe pressure-feed pump and a GJ cavity-style return pump driven by one common brushless Micropump I-Drive motor. 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.

The 84888 assembly was developed for Domino A-Series CIJ printers: one pump head supplies ink pressure and flow to the nozzle, while the second provides suction for recovered ink. Compatibility must be confirmed against the installed printer and service reference before ordering. 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.
