Ceramic Printing

Application Summary

Application Pattern Printing on Ceramic Tiles
Description Digital Printers are used to print patterns on ceramic tiles and other ceramic objects. The printing operation occurs before the ceramic is fired.
How Used A gear pump is used to supply ink to the print heads of the printer. The ink is continuously circulated over the inlets of the print heads to keep pigmentation particles in suspension; thus preventing blockage of the inlets.
Key Feature Abrasion resistant pump materials
Micropump Products CA, GJR and GJM
End Equipment Digital ceramic printers
Pump Function Circulation
Fluids Pigmented inks
Flow Rate 1 to 5 L/min (16-78 US gph)
Differential Pressure <60 psi (<4.2 bar)

Application Overview

The speed and flexibility of today's digital printers have opened up new opportunities for printed ceramic tile applications. These tiles are used for flooring, counter tops, and a broad range of decorative applications.

Micropump pumps are used in digital ceramic tile printers to circulate pigmented ink over the inlets of the print heads. This circulation is important to keep the pigments in suspension and prevent blockage of print head inputs.

PUMPING REQUIREMENTS MICROPUMP SOLUTIONS
FLOW RATE: 1 to 5L/min (16 to 78 USG/hr) We have variable speed pumps for this application with gear pump flows from 0.158 to 3.52 L/min (2.5 to 56 USG/hr) and centrifugal pump flows from 4 to 24 L/min (68 to 374 USG/hr)
LONG LIFE WITH ABRASIVE, PIGMENTED INKS Our pumps were developed specifically to handle abrasive, pigmented inks. We have life test results for abrasive white inks well in excess of 20K hours.
LEAK FREE OPERATION Our magnetic drives eliminate dynamic shaft seals, keeping fluid securely inside the pump and potential contaminants out.
SMALL PACKAGE SIZE Our magnetic-drive gear pumps are small. When mounted to a Micropump electromagnetic EagleDrive™, we can offer a very compact pump and drive package.
LOW POWER REQUIREMENTS With no drag from dynamic seals in the mag-drive gear pump, and no moving parts in our EagleDrive, power requirements are very low.
