POWER PLANT APPLICATION SEALS

Stein Seal® Company has developed Power Plant Seals where application requires the sealing of larger boiler feed water pumps, booster pumps and condensate extraction pumps in power plants. In general, these applications are high pressure with far less than ideal lubricating qualities. Our mechanical seals have designed to work in these conditions with less mean time between failure.

SSFWB

SSFWB seal is a balanced, internally mounted, pusher type cartridge seal with static multi-springs. Secondary sealing elements are elastomeric O-rings. Mainly used in application involved in the sealing of larger boiler feed water pumps in power plants. Seal faces are highly loaded in a fluid with far less than ideal lubricating quality.

SSBPSB

SSBPSB seal is a balanced, internally mounted, pusher type cartridge seal with static multi-springs. Secondary sealing elements are elastomeric O-rings. Mainly used in Booster pumps which are placed before the main pump to boost the inlet pressure of main pump to avoid cavitations due to low Net Positive Suction Head.

SSCESB

SSCESB seal is a balanced, internally mounted, pusher type cartridge seal with static multi-springs. Secondary sealing elements are elastomeric O-rings. Mainly used in Condensate Extraction Pumps (CEP) which extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank.
