The practice of insulating over metallic expansion joints to minimize heat loss in a piping system may be common, but it is not a good idea to follow this same practice with rubber expansion joints. ...
In food-processing applications, this technology excels at product recovery and waste reduction.
Because of the substantial concentrations of solids that these pumps handle, end users must understand the available sealing options.
Gasket information and the tests used to generate it can help users make the best possible equipment selections.
Two sets of seals, in service for 11 and 15 years, still meet baseline standards.
The balance between cost and ease of installation should be the major deciding factor.
The facility replaced old grinder pumps with stainless steel shredder pumps, which have needed no maintenance in almost two years.
While this type of pump is ideal for high-viscosity liquids, it can present users with unique challenges.
These recommendations can help end users prevent equipment degradation in pulp and paper applications.
This equipment avoids the risk of leaks and pipe damage associated with injection mold pumps.
End users will consistently purchase these critical wear components.
In outdoor pump installations, the effects of a hot climate and exposure to the sun should not be taken lightly.
Performing maintenance tasks correctly the first time has become increasingly important to end users. Today’s end users are tasked with doing more work with less time, fewer resources and smaller...
Many associations, societies and regulatory agencies have rewritten and redeveloped emissions and leakage standards and controls year after year. The partial list of organizations—based on voluntary...
Abrasive processing and wide temperature range are some of the pumping difficulties for high-performance liquid chromatography.
Lip and labyrinth seals provide protection in harsh oil and gas applications.
Appropriate equipment selection and best-practice maintenance procedures can make a difference in reliability, service life and production.
The construction, seals and protective monitoring contribute to the motor’s ability to operate in and under water.
Correctly selecting and installing the ideal component provides significant health, environmental and economic benefits.
This equipment eliminated a SAG copper mill gearbox’s maintenance issues resulting from contact lip seals that had a short and unreliable service life.
