Type-LRB25KU-R/LRB25NU-R

CHARACTERISTICS:

• Balanced.

• Not dependent on the rotation direction.

• Single cylindrical spring.

OPERATING LIMITS:

d1= 10 ÷ 100 mm p= 20 kg/cm²

v= 15 m/s t= -15÷ +200oC (*)

(*) The temperature resistance depends on the material of the secondary seals used.

The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application.

DESCRIPTION:

An extremely versatile general-use mechanical seal. It has metal tabs that reduce fatigue and tension in the rubber bellow when in the working position. A balanced seal without the need for a stepped shaft.

The seal can operate in applications with high pressures without suffering premature wear.

Types:

LRB25KU-R and LRB25NU-R: standardised dimensions in accordance with standard EN 12756 (KU and NU respectively).
