Product Detail Gutter pump / vacuum pump is used for Domino A420i and A520i inkjet coding printers (applicable to A320i as well). It is designed for the ink recovery system section and is suitable for gutter pump replacement, vacuum pump maintenance and ink return system repair work. This pump creates stable negative pressure to recover unused ink drops from the gutter, returning them to the circulation system, which is critical for maintaining print quality and reducing ink waste. The pump is typically a diaphragm type with chemical-resistant materials compatible with aggressive solvents such as MEK. The product is available as a compatible replacement part with one-year warranty. Customers should confirm whether their existing printer model and pump configuration are compatible before ordering.
