FBU double cartridge seal 2240
Double-balanced design, ultimate reliability
Typical applications:
The double-balanced design of 2240 ensures reliable and long-lasting operation under the most demanding conditions. This seal is typically used in pumps for abrasive and environmentally hazardous liquids in pulp and paper mills. Applications include also demanding services in food, metal and fertilizer processes.
The 2240 seal is especially designed for the Sulzer AHLSTARUP pump series.
Features and benefits:
• Seal utilizes the integrated and advanced SmartFlow seal water control technology.
• More than 90% seal water savings compared to normal flow control system.
• Single spring located in the stationary part of the seal. Material is corrosion resistant and flushed with seal water.
• Shaft misalignment does not pulsate the spring nor wear out the O-ring.
• Heat shrunk SSiC/SSiC,  seal faces as standard materials.
• The piston design of the seal enables large axial movement that does not have impact on spring loading.
• No measurements required for installation. Easy installation reduces risk of human error.
• Seal installation does not require back plate removal and the seal is fastened with one bolt which guarantees fast trouble free installation.
• Torque transmission with super elastic devices combined with no drive pins at seals faces. This eliminates possible start-up failures.
• Even in standard models, PTFE is used in O-ring positions where they are exposed to the process liquid.
• The special double-balanced design allows the use of both pressurized and non-pressurized sealant.
