Pumping fluids which contain
abrasive particles, such as those found in inks and paints can have a detrimental
effect on pump performance with erosion being a key factor in reducing pump
life. With these challenging fluids in mind MICHAEL SMITH ENGINEERS has
introduced the White Ink pump, the latest addition to the MICROPUMP range.
This modified GJ series Micropump
was originally designed for ink jet applications and has the ability to cope
with titanium pigmented inks, (those containing 7 micron titanium particles).
The pump's key wetted components have been effectively ‘armour plated' so they
are able to withstand corrosive and abrasive fluids. For solvent based fluids,
the White Ink pump features metal gears with ceramic shafts and a pump head of
specially hardened stainless steel. For water based fluids, the hardened
stainless steel body parts are titanium coated to overcome any possible
corrosion issues.
These compact and lightweight,
leakfree magnet drive gear pumps are designed to provide flow rates of around 3
lit/min, can generate a maximum differential pressure of 5.6 Bar and can be
operated on liquids with viscosities up to 1500 cP at temperatures up to
100ºC.
The external gear design ensures smooth,
pulse-free and highly accurate output, so the distribution of process fluids is
even and constant, as opposed to the more unpredictable pulsed flows from other
types of pump.
