Application Summary
Application
Pattern Printing on Textiles
Description
Digital Printers are used to print patterns on banners, bulk fabric, and garments.
How It’s 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
End Equipment
Digital textile 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)
Applications Overview
Reduced lead time, power consumption, material waste, water consumption, and CO2 elimination are strong drivers for the textile industry’s rapid conversion to digital textile printers. Markets addressed by these printers include Graphics Textiles, Garment, Décor, and Industrial.
WSF magnetic gear pumps are used in digital textile 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
WSF 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.
LOW POWER REQUIREMENTS
With no drag from dynamic seals in the mag-drive gear pump, power requirements are very low.
WSF Products Optimized for this Application
WSF gear pumps are most commonly used in this application. They provide reliable, smooth flow for ink circulation.
