Difference between containerized and non-containerized mechanical seals for ZJ slurry pump spare parts

The shaft seal of a slurry pump can be equipped with a mechanical seal, which can be further categorized into containerized and non-containerized mechanical seals. Today, let’s talk about the differences between these two types of seals.

A containerized mechanical seal consists of all the components of a mechanical seal, including the moving ring, stationary ring, spring, and auxiliary devices, assembled together. On the other hand, a non-containerized mechanical seal lacks certain components.

Containerized mechanical seals come with a shaft sleeve and seal gland, while non-containerized mechanical seals only consist of the moving ring and stationary ring. The containerized structure integrates all the components of the mechanical seal, allowing for easy installation and removal as a whole unit. On the other hand, the installation error rate is higher for non-containerized mechanical seals compared to containerized ones. Therefore, adopting a containerized mechanical seal structure can significantly reduce the failure rate of the mechanical seal. Containerized mechanical seals are easy to install and require only tightening of bolts.
