This seal is specially developed for bottom entry agitator seal working in polymer with seal size 7.75". Seal ring is Stationary:- & mating ring is rotating with shaft sleeve. Inboard faces are SiCTC out board are CarbonSiC . Viton O-rings are used as a sealing agent.

Seal series 22U, 73, 80U and 80B are to be used for compressors. These seals can be offered in variuos face combination. Many compressor manufacturer above seals from long time.

800 HB2 and mechanical seals for Booster Pumps, Drip Pumps, Condensate Pumps, Fuel oil Pumps, HSD Pumps, Ash slurry Pumps, Flue Gas Desulpherisation System Pumps and for Clinker Grinder seals. Increased Pump capacity is the trend in thermal and nuclear power stations because of high initial and maintenance costs. Pressure, shaft dimensions and speeds are considerably high. 800 HB2 seals incorporating thermohydrodynamic circulation grooves and pumping devices are effective even with speeds above 7000 RPM. The contrarotating pumping screws integrated into the seal allow for adequate cooling at the operating pressure to overcome head loss in the piping, filter and heat exchanger. Leak-Proof type 800 HB2 is a specially designed seal for feed pumps enabling normal running life of 20-30, 000 hours in continuous operation.

Series 95UUCK is factory assembled cartridge units on glass lined vessels. The seals are designed for handling severe services including products emitting toxic vapours during reaction process. The design incorporates bearing located very close to the seal. This standard feature effectively arrests the shaft whip for smooth and trouble free operation enabling enhanced seal life. The cooling jacket, also a standard feature, helps to maintain cool environment around the seal. Large clearance between rotating shaftsleeve and mating ring permits higher deflection of the shaft, invariably associated with top entry agetators.
