Type 21 mechanical seal for marine industry for water pump

Short Description:

The Type W21 is made of stainless steel, it provides a service range well beyond that which is possible with comparably priced seals of other metallurgical construction. The positive static seal between the bellows and the shaft, along with the free movement of the bellows, means that there is no sliding action could lead to shaft damage by fretting. This ensures that the seal will automatically compensate for normal shaft run-out and axial movements.

Features

• The drive band’s “dent and groove” design eliminates overstressing of the elastomer bellows to prevent bellows slip and protect the shaft and sleeve from wear
• Non-clogging, single-coil spring provides greater dependability than multiple spring designs and will not foul due to fluid contact
• Flexible elastomer bellows automatically compensates for abnormal shaft-end play, run-out, primary ring wear and equipment tolerances
• Self-aligning unit automatically adjusts for shaft end play and run-out
• Eliminates potential shaft fretting damage between the seal and shaft
• Positive mechanical drive protects the elastomer bellows from overstressing
• Single coil spring improves tolerance to clogging
• Simple to fit and field repairable
• Can be used with practically any type of mating ring

Operation Ranges

• Temperature: -40˚F to 400°F/-40˚C to 205°C (depending on materials used)
• Pressure: up to 150 psi(g)/11 bar(g)
• Speed: up to 2500 fpm/13 m/ s (depending on configuration and shaft size)
• This versatile seal can be used on a wide range of equipment including centrifugal, rotary and turbine pumps, compressors, mixers, blenders, chillers, agitators, and other rotary shaft equipment
• Ideal for pulp and paper, pool and spa, water, food processing, wastewater treatment, and other general applications
