FH-3 Ink Supply & Suction Pump

Compatibility and maintenance note: This item is used for compatible printer ink-line maintenance. Please confirm size, connector type, fluid path, material requirement, and printer configuration before ordering. Actual performance depends on installation, ink/fluid type, machine condition, and operating environment.

The FH-3 ink pump is used for compatible printer ink-line maintenance and ink-path service checks in UV and solvent printing systems. With two available configurations—supply pump and suction pump—it adapts easily to different printer ink paths and maintenance requirements.

Built with a durable micro gear motor and a sealed fluid chamber, the FH-3 pump should be matched to the printer ink path, tubing, fluid type, and installation condition. Its compact size and plug-and-play wiring make it an ideal replacement pump for many UV flatbed and photo printer models.

FH-3 Pump Options Comparison

Please confirm whether you need the suction version or the supply version before ordering to ensure proper compatibility with your printer system.

Typical Failure Symptoms

• Weak suction during cleaning cycles, unstable priming, or slow waste-ink discharge from the maintenance station.
• Unusual pump noise, inconsistent cleaning results, or repeated nozzle dropouts after normal maintenance.
• Ink residue around tubes or a maintenance station that no longer pulls ink smoothly during service cycles.

Fitment Checklist

• Confirm the exact printer model and maintenance-station layout before ordering.
• Match voltage, connector style, tube count, tube direction, bracket position, and overall body dimensions with the reference pump.
• If your printer has multiple pump revisions, compare the old part directly and confirm the manufacturer reference before purchase.

Service Pairing Suggestions

• Buyers often inspect cap tops, waste tubes, dampers, and wipers at the same time when replacing a pump.
• If the machine has been standing idle for a long time, check whether the tubing and capping station also need service.
• Use this part in a solvent workflow only when the fluid path and sealing arrangement match the reference system.
