Overhung Type OH2, 3, 4, Model NSI

Centerline support

The centerline support structure is designed to eliminate the effects of thermal expansion under high-temperature operating conditions.

Seal chamber

Seal chamber dimensions fully conform to API682 and API610 standards, with installation of dual seals also supported.

Air cooling system

Forced air-cooling by fan is standard for high-temperature applications. Operation up to maximum temperature of 250°C is possible without using cooling water on bearings. At temperatures over 250°C, a water jacket-cooling bearing housing is used.

  • Maximum flow rate:1500m³/h

  • Maximum diff. head:400m

  • Maximum operating temperature:400℃

  • Pressure rating:4MPa
