Rotomech single-acting cartridge mechanical seals are complete pre-assembled units ready for insatallation and operation. These cartridge mehanical seals are multiple springs (protected) type, balanced ,independent of direction of rotation, stationary design with long-hole fixing. Cartridge Assembly aids to fix mechanical seal in position ready for installation. These cartridge mechanical seals are designed for technically demanding applications - high degree of capacity for solids. Complete mechanical seal with sleeve and cover with circulation connections (quench optional). Exclusive use of solid seal face/ stationary seat - self-aligning arrangement in stationary design ensures safety of operation and usually increases service life. Mechanical seal is also very suitable with retrofitting of packing; usually fits into packing stuffing box compartments. Mechanical seal fits into DIN space for installation. 

Single spring seals are compactly designed to ensure efficient handling of liquids containing solid particles like slurries, sludges, sewage, viscous and abrasive materials. Both the faces of such seals are designed to take care of the presence of solid particles in the liquid which would otherwise damage the mating faces and contaminate the process.

Salient Features 
Single spring seals are engineered for non-clogging and self cleaning performance especially when handling contaminated liquids. The superior design of these seals helps to handle the considerable axial play of shafts during operation. The compactness of single spring seals ensures easy handling, installation and provides trouble free service with virtually no maintainence. 

We offer factory assembled single agitator seals which are duly hydro tested at required pressure. These seals find applications in glass lined steel and stainless steel mixers, agitators & reactors. These are used with non pressurised barrier fluid preferably clean water or oil. These seals can be supplied with cooling water jacket to ensure healthy environmental control near the seal area.

The rubber bellow mechanical seal has been designed for general sealing purpose which includes easy installation of the seal. The Seal has a unique rubber bellow secondary seal, which provides a high degree of axial flexibility to compensate for lack of concentricity of the shaft & misalignment & wear due to thrust movement of the shaft. The seal can be use regardless of direction of rotation since the driving torque is not transmitted through the coil spring, The required driving torque is enhanced through the unique rubber bellow which fits on the shaft through the interference fit between the collar, rubber bellow & the shaft.

Teflon Bellow seals are designed for handling acids. It is unrivalled in its ability to withstand corrosive fluids and is highly resistant to oxidising and reducing agents. That's because it is made out of chemically inert materials like PTFE, GFT, Ceramic, Carbon, Silicon Carbide, Hastelloy 'C' which come in contact with the acids during the operation and perform reliably under all, even extreme corrosive conditions.
The hydraulically balanced and flexible bellow accomodates shaft run-out and seal hang-up. These seals are also compactly designed for easy installation and virtually nil maintenance. The multiple springs with bellow provide uniform pressure all over the seal face to ensure effective sealing

Metal bellow mechanical seals are inherently balanced and are independent of direction of rotation. The unique feature of this type of seal is that, there is no dynamic 'O' rings and therefore it will never hang up or damage the shaft and sleeve, it also has an ability to handle corrosive as well as abrasive & viscous media. These seals have self-cleaning & non-clogging construction. With selection of special bellow material it can be used in highly corrosive media.
Generally used for handling highly corrosive chemicals, high Temperature applications, petroleum refinery etc.
