A liquid pump that suppresses pulsation and stabilizes ink supply.

In the printing industry, the stability of ink supply is a crucial factor that affects print quality. Ink pulsation can lead to printing inconsistencies and smudging, potentially reducing product yield. The FP70 series diaphragm liquid pump improves the stability of ink supply by suppressing pulsation, enabling high-quality printing. It also reduces pressure loss in the tubing and prevents the entry of air bubbles. This contributes to improved print quality and reduced maintenance costs. 【Usage Scenarios】 - Inkjet printers - Offset printing machines - Ink supply systems 【Benefits of Implementation】 - Improved print quality - Reduced ink waste - Decreased maintenance frequency
