piece design bearing housing for the Ball/Ball bearing
arrangement, as well as the patent pending split bearing
housing for the Sleeve/Ball and Sleeve/Tilt pad bearing
arrangement.
Bearing housings constructed in ASTM A216 Grade WCB carbon
steel. Three bearing arrangements available:
• Ball/Ball bearings
- Duplex 40° Angular Contact Bearing Set on the Non-Drive
End (NDE) to handle radial and axial loads. Bearing set is
supplied with a light clearance
- Deep Groove Ball Bearing on the Drive End (DE) to
handle radial loads
• Sleeve/Ball bearings
- Duplex 40° Angular contact Bearing Set on the Non-Drive
End (NDE) handle axial loads. Bearing set is supplied with a
light clearance.
- Babbitt lined Sleeve Bearings handle radial loads on NDE
and DE (Non Drive End and Drive End)
• Sleeve/Tilt pad bearings
- Tilting pad Bearings are installed on NDE to handle axial
load.
- Babbitt lined Sleeve Bearings handle radial loads and are
installed on NDE and DE (Non Drive End and Drive End).
- This bearing configuration utilizes an external pressurized
Lubrication Oil System (LOS) to lubricate and cool the
bearings. Both API, standard and custom designed systems
can be offered.
All bearing housings feature a 360° bearing saddle bolted to the
casing positioned with precision dowels for accurate, repeatable
alignment. The 360° bearing saddle is optimized for stiffness
and rigidity of connection between the pump casing and
housing along with increased bolt diameters. This provides Bearing housing put through rigorous testing.
significantly increased stiffness, resulting in reduced vibration.
The bearing housing exterior includes distinctive cooling fins
optimized by CFD/FEA analysis to aid in heat dissipation.

Patented Filters and Monitoring
Bearing oil contamination by wind-blown sand and dust
together with atmospheric moisture are major contributors to
bearings failing well before their design life. In an industry first,
all Ball/Ball and Sleeve/Ball include a cartridge filter assembly
that will help safeguard the bearing oil from debris
contamination. The patent pending filter cartridge will also
continuously work to scrub dissolved water from the bearing oil
utilizing specifically engineered moisture absorbing materials
built into the filter. The design allows for easy changeover of
filter cartridges even while the pump is operating – no need to
stop your process. All this additional reliability is achieved
without the need for additional oil pumps or piping – no
additional system complexity, monitoring, or control overhead.

Another smart feature included as standard is the award
winning, i-ALERT. This provides class leading continuous
machine monitoring with comprehensive wireless reporting
including diagnostic quality vibration FFTs and operating history
to the mobile phone or tablet of your choice. The bearing
housings come equipped as standard with constant level
oilers¹, sight window¹ and provisions for instrumentation
including: RTD’s, proximity probes¹, and accelerometers. If your
monitoring needs change in the future, this comprehensive
approach allows field retrofitting of almost any monitoring
scheme without replacing your bearing housings or relying on
ad-hoc instrument mounting.
