Elastomer seals taking the pressure
“When the going gets tough, the tough get going” is as true for seals as it is for motivational training. Seals are increasingly being used in extreme processing environments, and pumps are no exception. Paul Haworth, technical manager at Precision Polymer Engineering looks at how recent elastomer seal developments are coming to the aid of the pump engineer. more

How to maximize bearing service life in pumps
Nominal rolling bearing life in centrifugal pumps may range from 20,000 to 80,000 hours. However, the actual service life is determined by many factors - premature bearing failures cause costly equipment downtime, sometimes even with very serious consequences. Bearing experts from NKE Austria suggest some simple yet practical tips to optimize bearing performance. more
