Cartridge Mechanical Seals for Centrifugal Pumps

Cartridge mechanical seals for centrifugal pumps are built for high performance and easy installation. These fully self-contained mechanical seals are pre-assembled, factory pressure tested, and shipped as a one-piece unit. Installation often requires little more than removing a few bolts and/or set screws, inserting the seal unit itself, and replacing the fasteners. 

This design helps reduce errors caused by incorrect installation or improper assembly, and eliminates the need for users to measure and set spring compression. And, with all parts contained inside a durable housing, seal faces and other components are protected from possible damage during shipping, handling, and installation.

The Right Cartridge Mechanical Seal for Your Application

In most cases, our customers know the size and configuration of the cartridge seals they need. However, if you’re not sure what model is right for your centrifugal pump, the experts at Delmar can help you find the right option for your needs. We use a series of questions, called STAMPS, to ensure that you receive the proper cartridge mechanical seal for your pump. Please keep these questions in mind when specifying your cartridge seal:

  • S: Size of the rotating shaft to be sealed
  • T: Temperature range the cartridge seal will be used in
  • A: Application in which it will be used
  • M: Media the seal will be containing
  • P: Pressure range the cartridge seal will be used in
  • S: Speed it must withstand (maximum pump RPMs)
