Dft, Large Format, Uv Printer small ink pump

DTF large format UV printers use diaphragm or peristaltic ink pumps , which are available in Kenya with common specifications including a 24V DC power supply, 3W or 7W power consumption, and a flow rate typically between 100-400 ml/min, depending on the specific printer and ink requirements. General Specifications Type: Pumps are generally either micro-diaphragm or peristaltic pumps. Peristaltic pumps are often preferred for their ability to handle shear-sensitive white and metallic inks without contamination, as the ink only contacts the tubing. Voltage: They typically operate on a DC 24V power supply, compatible with most industrial printer power systems. Some models may be 12V DC. Power Consumption: Common power ratings are 3W for smaller/standard pumps and 7W for "big" pumps designed for higher flow rates. Flow Rate: The flow rate can vary based on the pump model and the printer's requirements, commonly ranging from: 100-200 ml/min (e.g., KHF-10 small pump model) 200-300 ml/min (e.g., FH-3 model) 300-400 ml/min (e.g., JYY big pump or KHF-30 models) Ink Compatibility: Pumps must be made with chemically resistant materials (e.g., high-grade nylon housing, EPDM rubber or fluorocarbon elastomer seals, PTFE) to withstand the corrosive components in UV-curable inks. Features: Many feature self-priming capabilities to reduce manual intervention and a sealed design to protect internal components from dust and moisture. Continuous recirculation functions are essential, especially for white ink, to prevent pigment settling and nozzle clogs. Pressure: UV ink delivery systems typically require precise pressure control, often in the range of 0.5-3 bar, which these pumps are designed to provide with low pulsation for consistent print quality.
