Pumps for reliable ink delivery in inkjet digital printing
KNF's maintenance-free and long-lasting gas and liquid pumps are used in the entire range of industrial inkjet printing:
For example, in digital printing systems for large-format banners, in decorative printing for furniture and ceramics, or in printing systems for barcodes and labels on packaging.
Customized complete solutions consisting of gas and liquid pumps ensure continuous ink delivery. The diaphragm pumps are precisely designed to meet the special requirements of inkjet technology.
|Delivery rate at atm. Pressure (ml/min)||max. suction head (mWS)||max. pressure head (mWS)|
Ink supply: Direct delivery of ink to the printhead
|50 - 6. 000||3||10|
|Print head cleaning||100 - 250||3||10|
|Purging||30 - 300||10|
|Ink circulation||600 - 1. 200||3||10|
|Delivery rate at atm. Pressure (ml/min)||Vacuum (mbar abs.)||Overpressure (bar)|
Ink supply: Indirect pumping by pressure overlay
|3.3 - 4.5||220 - 300||1, 5|
|Degassing||3.1 - 5||7 - 70||0.3 - 1.5|
|Print head cleaning||3, 1||240||1,4|
|Purging||3,1 - 4,5||1,4 - 1, 5|
|Vacuum generation at the print head for the meniscus effect||0.33 - 3.1||240 - 663||0.37 - 1.4|
