TOPSFLO gear pumps were developed specifically to handle abrasive, pigmented inks. Precise
flow and pressure requirements are driven by the design of the printheads. TOPSFLO pumps
deliver a pulseless flow which is key to preventing issues in print quality and drop placement
accuracy.

Operation
Figure 1. below shows a simplified version of a typical ink supply system for a printer with recirculating inkjet
printheads.Filtering and heating elements have been omitted from the diagram, but it should be pointed out
that pulse dampeners are typically not required when gear pumps are used. Pumps A & B control the flow
through the printheads and the pressure at the inlet and outlet manifold. Adequate flow should be maintained,
as recommended by the printhead manufacturer, to assure removal of particles and air bubbles blocking
printheadnozzles, and to assure the ink is homogeneous and at constant temperature.
Ink Supply System for Recirculating Inkjet Printheads
System Requirements
Precise flow and pressure requirements are driven by the design of the printheads. In "Drop On Demand"
inkjet printing, ink drops are ejected from a printhead "on demand" by one of a variety of physical processes,
often using piezoelectric materials to force ink from the printhead. Between drops the ink is held in a nozzle by
surface tension forces, forming a meniscus. The stability of the meniscus is important to drop placement
accuracy and the resulting print quality. Any pulsation in the recirculating ink stream can result in an unstable
meniscus, thus a pulseless flow is very important.
Typical Application
Industrial digital printing, DOD and CIJ printing
Wide-format printing
Packaging printing
Decorative printing on ceramics, glass, wood
Metal and plastic
Labelling, marking
Textile printing
Ceremic printing
