End users will consistently purchase these critical wear components.
With no mechanical seals to replace or maintain, these pumps provide a cost-effective option for hygienic applications.
The balance between cost and ease of installation should be the major deciding factor.
The industry has developed a specialized method over time.
Avoid these root causes of seal failure.
This discussion opens a three-part series covering mechanical seal piping plans that provide guidelines for various seal arrangements, fluids and control equipment to help you determine what support...

What is the impact of reliability on the sealing system energy footprint from pump shut down, repair and re-commisioning?
Last of Four PartsThis is the last of a four-part “Sealing Sense” series that has provided guidance on the best practices to minimize the size of the sealing system energy footprint. The first...
What is the Energy Footprint of Sealing Systems?
The term carbon footprint has become synonymous with greenhouse gas (GHG) emissions and climate change. Carbon footprint commonly refers to the volume of greenhouse gases, the most prominent of which...
Efficiency Through Indirect Measures
Indirect factors can directly impact the true efficiency of the product-transfer process, if not considered and monitored.For months, the focus of the Pumps & Systems "Efficiency Matters" column...
Initial costs and life cycle costs affect which sealing method is chosen for an application. If a sealing device cannot be considered an investment or will not produce an immediate return, there is...
One approach to improving mechanical seal performance is to upgrade to a sintered silicon carbide composite material. Silicon carbide based materials have been increasing the limits of mechanical...
Such a question often comes up when it is time to recondition a mechanical seal: We use several different brands of mechanical seals in my plant. When a pump is taken out of service, we usually send...
Five performance factors affect the life of a mechanical seal and guide the determination of an optimum replacement cycle for that seal. They also lead to improved seal life and mean time between...
Because of the unique problems experienced with highly viscous fluids that can crystallize to form abrasive particles, as well as those with adhesive tendencies, an alternative to face seals is often...
Agitator Seal Runs Without Fail for 13 years
Due to heat-shrink technology, agitator seal functions failure free for more than a decade.The year 1997 started with some memorable events depending on your political and/or sporting interests. On...
