Why Diaphragm Pumps Superior Choice for CIJ Printer Performance

Diaphragm pumps are ideal for Continuous Inkjet (CIJ) printers for several reasons, as they match the specific requirements of CIJ technology. Here are some of the reasons why diaphragm pumps excel in this application:

1. Precise Fluid Handling

CIJ printers require precise and consistent ink flow for the creation of uniform ink droplets. Diaphragm pumps offer excellent control over fluid pressure and flow rates, ensuring that the ink supply remains steady without pulsation or inconsistency. This is crucial for maintaining the high-speed, continuous nature of CIJ printing.

2. Chemical Compatibility

CIJ inks often contain aggressive solvents and inks. Diaphragm pumps are designed with chemically resistant materials such as PTFE or elastomers that can withstand corrosive and abrasive fluids, ensuring longevity and reliability. Diaphragm pumps provide a sealed operation, which reduces the chances of leaks, ensuring the containment of ink and solvents and contributing to the overall reliability of the CIJ printer.

3. Faster start due to  Self-Priming and Dry-Running Capabilities

Diaphragm pumps can self-prime, which means they can start up without needing pre-filled ink lines. This reduces operational delays and helps in quick setup. Additionally, they can tolerate dry-running for short periods without damage, ensuring the pump isn't compromised if there's a brief interruption in the ink supply.

4. Leak-Free Operation

In CIJ printers, avoiding leaks is critical to maintaining the cleanliness of the print environment and preventing solvent evaporation. Diaphragm pumps provide a hermetically sealed operation, which prevents leaks and contamination of the ink or solvent system.

5. Minimal Maintenance

CIJ printers are frequently used in a demanding environment, and maintenance downtime can be pricey. Diaphragm pumps feature minimal moving parts and are intended for long-term use without frequent servicing. Instead of replacing the entire pump, KGK Jet is offering to replace pump parts which helps reduce maintenance cost and operational interruptions.

6. Energy Efficiency

Diaphragm pumps are relatively energy efficient, contributing to lower operational costs. In a CIJ printing environment where the pump runs continuously, energy efficiency becomes an important factor in overall system efficiency.

7. Lower Total Cost of Ownership (TCO)

By combining the benefits of low maintenance, long lifespan, energy efficiency, and reduced ink/solvent consumption, diaphragm pumps in KGK Jet CIJ printers lower the total cost of ownership. Over time, customers experience significant savings in terms of:

• Operational efficiency: Fewer breakdowns and smooth fluid control.

• Consumables: Optimized use of ink, solvents, and make-up fluids.

For customers using KGK Jet CIJ printers, diaphragm pumps provide substantial savings by reducing maintenance costs, enhancing energy efficiency, optimizing ink and solvent usage, and offering long-lasting, versatile performance. These advantages translate to both immediate and long-term cost reductions, making CIJ printing more cost-effective.
