AES Single Seals (AES CURC)

The AESSEAL CURC™, CRCO™ and CURE™ mechanical seals are part of a range of seals specifically designed to optimize the use of Silicon Carbide. All these seals incorporate improved third generation self aligning technology. The design objective was to minimize metal to Silicon Carbide impact, particularly on start–up. 

In some seal designs, impact between metal anti–rotation pins and Silicon Carbide can be sufficiently severe to induce stress cracking in the Silicon Carbide. Silicon Carbide has many advantages when used in mechanical seals. The material has superior chemical resistance, hardness and heat dissipation properties compared to practically any other material used as a mechanical seal face. Silicon Carbide is, however, brittle by nature, so the design of the self–aligning stationary in the CURC™ range of mechanical seals seeks to minimize this metal to Silicon impact on start–up.

AES Single Seals (AES SCUSI)

A short externally mounted cartridge seal, with flush ports and self-aligning faces. With the aid of Finite Element Analysis (FEA), a range of seals were designed to optimize the use of Silicon Carbide. This third generation seal incorporates an improved self-aligning concept and prevents shock damage to Silicon Carbide on start-up, which is the most significant reason for Silicon Carbide damage in other seal designs.

In addition, the spring loaded rotary centrifuges solids away from the seal face and resists clogging, increasing the range of general service applications to include slurries and some abrasives. Faces remain flat, square to the shaft and suspended solids are prevented from crossing the flat seal faces.

Hydraulically balanced seal face technology for reduced power consumption, non-shaft-fretting sleeve elastomer and positive set screw drive. Multiple spring seal-face loading and stationary design suitable for high speed applications.

AES Split Seals (AES ISOS)

The ISOS™ (inflatable shut-off seal) is fitted between the pump and a radially-divided seal, to form a separate seal when required, allowing the quick and easy removal of the mechanical seal. The ISOS™ works around the principal of surrounding the shaft with an inflatable elastomeric bladder.

Under normal operating conditions, when the mechanical seal is working, the bladder remains unpressurized. When the mechanical seal fails or needs removing, the bladder can be inflated, thereby mechanically sealing the shaft. The seal can then be easily removed without draining or isolating the equipment.

AES Split Seals (AES RDXS)

The RDSX™ seal eliminates the need to remove or strip equipment for seal replacement. The self aligning rotary makes the RDSX™ one of the easiest and quickest to install split seals on the market today.

RDSX™ Features: Self-aligning stationary and rotary seal faces. Installation wear indicator, hydraulically balanced seal-faces and patented assembled spring retainer, unique ‘O’ring design and minimum parts.

The RDSX™ has been developed after extensive research and customer feedback to increase the ease of fitting the seal correctly – first time. A comprehensive product development and dynamic testing process makes the RDSX™ the ideal product to offer mechanical seal benefits over traditional packing solutions without increasing maintenance costs or downtime.
