Both split and cartridge seals are effective fluid sealing options when used in the right application. However, they are different types of mechanical seals, each made for specific scenarios. This article compares the differences between split and cartridge seals and examines the most common applications for each.

Split seals are quick and easy to install, and they are best used for a pump or equipment that can’t be taken offline—either because it is too large or because there isn’t enough room to take it apart (ie. equipment on a ship or barge). The advantage of split seals is that installation requires minimal downtime. One of the disadvantages is that split seals also tend to leak more so they cannot be used for applications where there is anything corrosive, toxic, or flammable. These types of seals are perfect for vertical turbine pumps and for the sealing of water.

A cartridge seal is a solid seal that has more broad-spectrum application, as it can go almost anywhere. Installing this type of seal requires a complete breakdown of the equipment so there is more downtime upfront to consider. These types of seals are perfect for centrifugal pumps and often make the best long-term solution as they don’t leak as easily as split seals.

“Choosing the best seal for a specific application doesn’t have to be a short-sighted decision. In some cases, end users choose a split seal to save on installation costs and time spent, even though their application requires a cartridge seal,” explains SEPCO Business Development Manager Cody Kaufmann. “We prefer to work closely with our customers to help them make informed decisions. For example, while a split seal does save time up front, there are many other factors to consider beyond time savings. No matter the application, we want the seal to solve the specific problem, and our experience determining that can make all the difference in the long run.

“At SEPCO, we want to provide you with the best long-term sealing solution versus putting a band aid on the problem. We make sure you get the right mechanical seal for your application the first time. This is what really saves you time and money.”
