Pump Structure
Bearing Design
-
Ball bearing
The standard bearing lubrication
uses oil rings. -
Sleeve bearing + Ball bearing
This type of bearing is lubricated
by oil rings.
The bearing oil is cooled
with the shaft fan as well as
the fins mounted on the bearing housing. -
Sleeve bearing
This type of bearing is used
for heavy thrust loads.
For this combination, a forced-feed lubrication system
conforming to the API 614/610 standard is employed.
