MS-CTX-ABDN
PRODUCT DESCRIPTION
* Dual Seal Configuration
* Balanced Design
* Independent of direction of rotation
* Cartridge construction
* Available for standard (CTX-ASDN) and big bore (CTX-ABDN) seal
chambers
* Double pressure balanced
* Designed with integrated pumping device for increased
efficiency in circulation
TECHNICAL FEATURES
* Ideal for use in ANSI process pumps
* O-Ring is dynamically loaded to present shaft damage
* Dimensional modification of the stuffing box chamber is not required
due to short radial installation height
* Ideal to convert and retrofit pumps with packings and large volume
OEM production
* Cartridge unit factory assembled for easy installation, which reduces
downtime
* Rugged design for long operating life
