Product Description
• Specification: H4.58 (corresponds to the thickness and geometric design of the precision gears housed within the pump body).
• Fully Compatible Models: Domino AX Series (specifically designed for models utilizing the FLD intelligent fluid system, such as the AX150i and AX350i).
• Core Materials:
• Ceramic Shaft: Constructed from high-purity industrial-grade precision ceramic, offering exceptional hardness and superior resistance to chemical corrosion—capable of withstanding highly volatile solvents such as those based on ketones (MEK) or alcohols. 
• Precision Gear Kit: Features self-lubricating properties and low wear characteristics, ensuring consistent ink pressure during high-speed operation.

FAQ
Q1: What does the "H4.58" specification in the DB-HGN1024 gear set signify?
A: "H4.58" indicates that the standard thickness (or height) of this precision gear is 4.58 mm. 
• Within the FLD (Fluid Delivery) pump system of Domino AX series printers (such as the AX150i and AX350i), gears of varying thicknesses—such as H4.58 or H4.60—are used depending on the specific pressure requirements of the model.
• When purchasing or replacing these parts, the specification must match exactly; an incorrect thickness can cause the pump to seize or lead to severe ink leakage.
 
Q2: Why is the shaft of the FLD pump in the Domino AX150i made of ceramic?
A: The inks and make-up fluids used in coding and marking printers often contain highly corrosive components, such as ketones (e.g., MEK) or alcohols. Furthermore, the pump must operate at high speeds 24 hours a day.
• Industrial-grade precision ceramic offers exceptional hardness and superior corrosion resistance. It ensures that the shaft remains undeformed and resistant to chemical erosion even under intensive, continuous operation, thereby extending the overall service life of the pump.
 
Q3: Under what circumstances should the DB-HGN1024 ceramic-shaft gear set be replaced?
A: It is recommended to replace the gear set immediately if your AX150i exhibits any of the following three typical symptoms:
1. Pressure Alarms: The system frequently triggers warnings such as "Ink pressure abnormal" or "Failure to build pressure," which persist even after the printhead nozzle has been cleaned. 
2. Abnormal Pump Noise: During operation, the pump emits a sharp, high-pitched grinding sound or irregular clicking/clattering noises. 
3. Poor Print Quality/Broken Lines: Gear wear causes fluctuations in ink pressure, resulting in distorted, incomplete, or discontinuous characters in the print output.
 
Q4: During maintenance, is it possible to replace only the worn-out gear while continuing to use the existing ceramic shaft? A: It is strongly recommended to replace the entire kit at once.
• The DB-HGN1024 is a high-precision, micron-tolerance component. Even if no damage is visible to the naked eye, the surface of an old ceramic shaft may already have sustained imperceptible wear.
• Pairing a new gear with an old shaft will result in uneven stress distribution during operation, accelerating the wear of the new parts and potentially causing the gear teeth to chip or break within a short period.
 
Q5: What other peripheral components should be replaced when installing the DB-HGN1024?
A: Whenever the FLD pump housing is disassembled, the solvent-resistant O-rings must also be replaced.
• Once old O-rings have been exposed to and swollen by solvents, reusing them after disassembly is highly likely to result in minor leaks. If ink seeps into the motor assembly located behind the pump, it could cause the entire, costly FLD pump unit to burn out.
Q6: Can you source specific coding/marking machine parts that are not listed on your website?
A: Yes, we can. Given the vast range of available parts, not all models are featured on our website. Please feel free to send us an inquiry at any time; we can also provide our latest and most comprehensive product catalog. Once we receive your request, a dedicated representative will get in touch with you promptly to assist with a price quote.
