Product Description
TECHNICAL FEATURES
•Stationary compensating seal end face with double-balanced design, ensuring stable operation even under pressure fluctuations.
•Wave spring compensation structure, delivering stable spring compensation performance.
•Double mechanical seal with single-set spring configuration and piston-type sliding O-ring design, featuring large axial runout that does not affect spring load.
•Modular design with standardized universal components, facilitating reduced maintenance costs.
•The spring is not in contact with the medium, ensuring a long service life of the mechanical seal.
•Positioned by the shaft shoulder for easy installation, which reduces the risk of human error. No measurement is required during installation.
•Inlaid ring surface structure: the seal ring has no drive pin, avoiding seal face rupture during startup.
PRODUCT DESCRIPTION
Dimensions Compliant with Sulzer AUP Pumps, Covering Shaft Diameters Including 30, 40, 50, 60, 80, 90.
TYPICAL INDUSTRIAL APPLICATIONS
The 2240 Series features a double-balanced design, ensuring reliable and long-lasting operation of pumps under harsh conditions. Specifically engineered for demanding applications in the pulp and paper industry as well as stock applications, this seal is typically used in pumps handling abrasive and environmentally hazardous liquids in digesters, evaporation, and causticizing facilities of pulp mills. Designed as a pressurized double mechanical seal, its double-balanced function allows it to be utilized as an unpressurized double-ended unit. The Type 2240 seal is exclusively tailored for Sulzer's AUP Series pumps.
