EQUIPMENT SHOWCASE
Turbines-whether powered by steam,
water, natural gas, or some other fluid-
are vital to the generation of electricity.
Many companies in the power industry
are focused on designing, manufacturing,
and servicing turbomachinery equipment
and components that support turbine operation.
POWER highlights a handful of
them in this equipment showcase.
Philadelphia Gear Equipment
Key for Coal Plants
Even the finest engineered enclosed
drives reach a point where they need
to be repaired, whether due to changes
in manufacturing needs and process
improvements, or wear and tear from
long-term use in demanding applications.

Power Systems, wants to ensure customers
always have state-of-the-art gear
drive technology (Figure 1), and wants
to prevent unplanned downtime through
regular gearbox maintenance and repair.
Philadelphia Gear delivers creative engineering
solutions for the power generation
industry that increase production
capacity, provide fast and precise control
under all conditions, and offer softstarting
for a longer lifetime of electrical
and mechanical equipment through Synchrotorque
technology. Philadelphia
Gear manufactures and repairs conveyor
drives, ball mill drive systems, roller mill
drives, and classified drives, primarily for
coal-fired power plants. These facilities
throughout the U.S. and across the globe
rely on the expert and efficient gearbox
repair services of Philadelphia Gear to
keep their field operations running as
successfully as possible. Philadelphia

ACT Offers Parts, Repair of
Compressors
Advanced Compressor Technology (ACT)
recognizes that quality repair is just one
fact of asset care. Achieving the highest
level of reliability and availability requires
a commitment to a total service package.
ACT provides several services to
the power generation community, including
engineering, which includes machine
design; operations, including recommendations
and support; and maintenance

customers solve centrifugal pump and
other rotating equipment problems with
upgrades to non-metallic wear rings,
and non-metallic bushings and bearings
made from materials such as DuPont

(Figure 2), including preventative measures
for optimizing performance and
avoiding costly failures. ACT responds to
these requirements through engineered
solutions for customers. The company
has an engineering and design focus
for custom manufactured components
with consideration for materials, service,
and process conditions. ACT also develops
operational strategies and support
for optimal equipment performance in
the field. The company's preventative
maintenance management services
are focused on sustaining asset operations
at the highest level of reliability and
availability. ACT provides supervisors
and technicians for the maintenance
of centrifugal compressors and other
equipment, including offering parts and
services, along with field work, for reciprocating
and centrifugal compressors.

Bearings, Rings Improve
Centrifugal and Rotating
Equipment
Boulden Co. is a global supplier of composite
materials and machined parts for
centrifugal pump and rotating equipment
wear components. The company's
selection of components includes
non-metallic pump wear rings (Figure
3); composite bushings; non-metallic
pump bearings; throttle bushings; throat
bushings; agitator bearings; and vertical
pump shaft bearings. Boulden helps
Vespel CR-6100 and Boulden B-Series
composite materials. The use of nonmetallic
pump casing rings improves the
ease of operation of pumps. If you have
a seized pump, upgrading to composite
wear rings and composite bushings will
essentially eliminate the risk of having
the pump seized a second time. If you
have a dry-running pump, non-metallic
wear rings and bearings can often survive
these conditions without failure and
minimize the damage to your expensive
pump components like impellers and
casings. Likewise, nuisance issues like
having a pump jammed up or galled during
alignment and commissioning are
eliminated. Boulden Co., Conshohocken,

reduction in the required containment
structure, reducing the magnetic gap,
which allows for higher power density.
The result is an efficient, compact, highspeed
solution for use in a broad range
of power and propulsion applications.
The company's generator solutions can
direct couple with gas turbines (Figure
