Project Description

RT155

EagleBurgmann Type BT-FN Replacement

Mechanical seal type RT155 with conical spring and O-ring pusher construction, the metal parts produced by Stamping. competitive price and wide range of application have made the RT155 a mass-production seals.

Features

  • Conical spring,unbalanced,O-ring pusher construction 

  • Torque transmission via conical spring, independent of direction of rotation.

  • Stamping construction in the metal parts

Recommended Applications

  • Centrifugal pump and clean water pump 

  • Other Rotating Equipment

Operating range

  • Shaft diameter: d1=10…40mm

  • Pressure:  p=0…1.4Mpa（203psi）

  • Temperature: t = -40 °C …180 °C(-40°F to 356°F)

  • Sliding velocity:  Vg≤15m/s（49.2ft/m）
