Type 202E pump mechanical seal is widely used, with special balance type, which can be used at higher pressure, higher operating speed and lower wear. Short working height can install very short stuffing box, with compact structure, strong compatibility and convenient installation.

It is frequently used by the pulp and paper, petrochemical, food processing, wastewater treatment, chemical processing and power generation industries.

Features

single seal, unbalanced, independent of direction of rotation

design standard: ISO3069 DIN24960 EN12756

To absorb both breakout and running torque, the seal is designed with a drive band and drive notches that eliminate overstressing of bellows. Slippage is eliminated, protecting the shaft and sleeve from wear and scoring.

Automatic adjustment compensates for abnormal shaft-end play, run-out, primary ring wear and equipment tolerances. Uniform spring pressure compensates for axial and radial shaft movement.

Special balancing accommodates higher-pressure applications, greater operating speeds and lower wear.

Non-clogging, single-coil spring allows for greater dependability than multiple spring designs. Will not run foul due to fluid contact.

Low drive torque improves performance and reliability.

Parameters

Pressure:p1 = 28 bar (406 PSI)

Temperature:t = -40 °C(-40°F) … +210 °C(+410°F)

Sliding velocity:vg = 13 m/s (43 ft/s)

  • Dependent on medium, size and material

Application Medium

including water, refrigeration, oils and chemicals.

Application

Fits equipment with confined space requirements and limited seal chamber depths in pumps, mixers, blenders, agitators, compressors and other rotary shaft equipment.
