White Ink pump copes with fluids containing abrasive particles
Michael Smith Engineers is launching the White Ink pump, the latest addition to its Micropump range, for pumping fluids that contain abrasive particles - such as those found in inks and paints. Abrasive particles can have a detrimental effect on pump performance, with erosion being a key factor in reducing pump life, but the White Ink pump has been designed to cope.
This modified GJ series Micropump was originally designed for ink jet applications and has the ability to handle titanium pigmented inks (containing 7micron titanium particles). The pump's key wetted components have been '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, lightweight, leakfree magnet-drive gear pumps are designed to provide flow rates of around 3litres/min, can generate a maximum differential pressure of 5.6bar and can be pump liquids with viscosities up to 1500cP at temperatures up to 100degC.
The external gear design provides a smooth, pulse-free and highly accurate output, so the distribution of process fluids is even and constant; trhis is said to be in contrast to the more unpredictable pulsed flows that can be delivered by other types of pump.
