New pump and seal options reduce hefty repair and maintenance costs

In tough applications, robust pumps are clearly a must, but if maintenance and repair costs have escalated to the point of ridiculous, it’s time of course to consider some alternatives.
Pumping Titanium Dioxide isn’t the easiest. Used primarily for consumer electrical goods with its brilliant white colour, this slurry solution of titanium dioxide powder and base/carrier fluid is extremely abrasive. Certainly not for any old pump, but when the cost of a brand-new replacement – so long as of course it can do the job (!) is cheaper than a repair, then it’s a true no brainer not to improve the economics of the process.
Such a scenario presented itself recently to a rotary lobe pump manufacturer, who has already created a very successful track record at plants in the same areas of industrial Humberside and North Lincolnshire. As a low-friction, almost pulsation-free pump, it would meet the requirement for Titanium Dioxide to be gentle on the important pigments, but what about the pressures and the seals?
“We knew that with our ONIXline pumps, we could handle demanding high pressures up to 16 bar”, said David Brown, Managing Director of Borger UK. “And...
