Mechanical Seals & Sealing System

We provide Mechanical Seals of reputed manufactures as per requirement. Additionally we support design, production and supply of customised seals for critical application. We can offer various different commercial agreements, like, ARC on supply of various seals and spares existing in your plant which can be designed as per your need.

MULTI SPRING SEAL

Type S-VT- 9 /S- VT – 9W are multi spring, pusher type unbalanced seals used for universal applications. The seals are compact in design suiting all types of rotating equipment, 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, VT- 9 can be converted to VT – 9W by just changing the seal ring and the secondary member.

AGITATOR SEAL

Type S- VCB – SH/C1 are present factory assembled cartridge seals for use in Agitators, Mixers and Reactor Vessels. The seal construction varies slightly for top entry vessels, side entry vessels and bottom entry vessels. The seals are designed to the shortest shaft length and the bearings are located as close to the vessel body to minimize the deflection.
