KNF FP7 Series FP25 Pulsation Mitigation Diaphragm Liquid Pump

Pulsation-reducing liquid pump, a diaphragm liquid pump that significantly reduces pulsation generated during pump suction and discharge.

We have reviewed the design of the pump itself as a liquid pump for pulsation reduction measures. Previously, pulsation reduction was achieved using dampers, but now the pump itself significantly suppresses pulsation. - FP7 Series / FP25 Series The pulsation reduction damper has been integrated with the pump. Two types are available: brushed DC motors and brushless DC motors. Digital customization is also possible with the brushless DC motor.

Recent technical challenges of KNF's ink supply system.

About the latest diaphragm pumps in inkjet printers.

To develop a new ink pump, we first need to look at the end of the inkjet system's value chain... - The next generation of print heads requires high flow rates with minimized pulsation. - High flow rate with reduced pulsation - low pulsation technology. - The stability of the meniscus is crucial for high printing dynamics. - KNF pumps in the degassing system.
