CMS Standard Cartridge

Description

Our standard, balanced and cartridge CMS Standard Cartridge is available in variants for ANSI pumps (CMS-SN, -SNO, -TN, -QN) and is independent of the direction of rotation.

This type of standard cartridge closure is characterized by being a very economical mechanical seal and easy installation thanks to its pre-assembled unit (reduced downtimes). In addition, it is ideal for standardizations. During assembly, there is no damage caused by the dirt introduced. The shaft is not damaged thanks to its dynamically loaded O-ring. It can be used in universal conversions of original packaging, retrofits or equipment.
