Series AES-001 is single conical spring, unbalanced seal with O-ring provided for secondary sealing. Since the Torque transmission is done by the single coil springs the seals are dependent on the directions of rotation, which is seen from the drive end of the shaft. Right handed spring and left handed springs are provided for clockwise and anticlockwise rotating shafts respectively. These seals can carry a variety of seals faces, serving applications in submersible, sewage, chemical transfer, water pumps etc.

Series AES-002 is unbalanced single acting helical coil spring seals independent of direction of rotation. The drive ring's notch design eliminates over stressing of the elastomer bellows. Slippages are eliminated, protecting the shaft and sleeve from fretting. Seal can be repaired in field with minimum spares, minimizing the downtime cost.

Series AES-004 is single coil with rubber bellow mainly for use in wast water treatment plants in the sewage applications. The rubber bellow protects the shaft / sleeve from fretting. The bellows is not subjected to any torsonial stress. Torque transmission is through the spring and spring holder. Self aligning features accomodate abnormal shaft runout and primary sealing wear. The single coil spring will avoid effluent particles.

Series AES-005/006 are multi spring, pusher type unbalanced seals used for universal applications. The seals are compact in design suiting all types of rotating equipments, pumps and mixers. Drive lugs in the retainer will provide torque transmission and reduce slippage on shaft and sleeve. A snap ring holds all components together, helping in easy installation. The parts are interchangeable, AES-005 can be converted to AES-006 by just changing the seal ring and the secondary member.

Series AES-009 is single coil spring seal developed for light contamination, dirty media and clogging type application. These type also allows it to fit onto a normal shaft without any balancing step. The mechanical drive of this seal is realised by grub screw which lock onto the shaft. The seal has a limited axial length, compact shape which allows easy mounting.

Series AES-010 seals are widely used in refining, petrochemicals and chemical industries. Static o-ring is used as a secondary member. The absence of dynamic o-ring prevents possibility of seal hang-up. Centroid loaded face design increases seal life by avoiding seal face distortion caused due to thermal expansion and also ensures optimum face flatness over a wide operating condition. As a standard, AM350 bellow cores are used. For chemical compatibility Alloy C-276 or Alloy 718 bellow cores can be used.

Series AES-016 Grundfos pumps seals are very easy to replace and gives maximum reliability. It is durable and made from hardwearing material which prevent he downtime and prolong the lifetime of the seal. All axial movement has been eliminated, preventing wear of the shaft and the rubber parts. There is o special tool required to replace the seal or dismantling the pump.

It gives long and reliable seal life. Easy to install without any tool

Series AES-017 mechanical seals are designed for heavy duty service involving high pressure and sliding velocities. This seal has positive drive arrangement and sturdy construction making the seal suitable for high pressure application. Multiple spring design provides uniform face loading. The seal is supplied as a cartridge unit and can be directly bolted to stuffing box. These seals are normally used in main oil pipelines, water injection pumps and boiler feed water pumps.

Series AES-018 is a compact cartridgised balanced seal specially developed for handling slurries, sludges, thick syrups and polymerising fluids. In the cartridge construction the springs are isolated from the fluid enhancing the seal life. After detaching of the location plates provided, the seal can be easily installed straight away without setting measurements. Series AES-018 is a sturdy, robust, seal capable of maintenance free runs for years together.
