22. Refinery Vertical Turbine
Pumps
Problem:
Vertical turbine style pumps are widely used in refinery
applications to lift fluids from sumps, pits or tanks. These pumps
have a shaft that extends down inside a pipe and connects to a
series of stacked turbine impellers, each nested inside a bell
housing. During operation, fluid is drawn up the pipe from the
suction created by the rotating impellers. After extended use, the
impeller blades become worn which creates a gap between the
blade tips and the bell housings – reducing the pump’s
efficiency.
Solution:
TB Wood’s introduced the AVS Series coupling specifically to
improve vertical turbine pump efficiency. The AVS (Adjustable
Vertical Spacer) coupling connects the motor to the long impeller
shaft. A threaded adjustment nut allows operators to increase

needed a unique coupling solution for its line of mobile
baggage and cargo conveyors. The diesel- or electric powered
belt loaders support a wide range of commercial aircraft. The
coupling is positioned between the drive engine/motor and a
hydraulic pump that raises and lowers the conveyor belt ramp.
Solution:
The OEM determined that unique Gear Grip couplings
available only from Guardian Couplings, with a large 7.5
degrees of
angular misalignment, met its application requirements.
• Lightweight and compact
• In-shear rubber sleeve design acts as a fail-safe in the event
of an overload condition preventing damage to the expensive
drive system components.

Tempura Batter Mixers
Problem:
A leading global food processing OEM needed a robust geared
motor solution for a line of tempura batter mixers. The machines
gently mix a precise ratio of water and bagged ingredients to
ensure that the batter achieves the ideal consistency. After the
tempura is mixed, it is transferred, via an onboard pump, to an
adjacent batter applicator. Geared motors are used to drive the
rotating mixing cage as well as the positive displacement pump.
Solution:
The OEM contacted Bauer for a reliable solution. After review of
the application requirements, Bauer supplied modified Model
BK17 and BK08 geared motors to drive the machine’s mixer and
pump. The BK models feature PMSM (permanent magnet
synchronous motor) that reduce heat losses from the rotor by
100% and total losses by approximately 25%, while increasing
total efficiency by 10% or more.

50. Hydro-Mulchers
Problem:
Bowie Industries, a major hydro-seeder manufacturer, was
looking for an electric clutch solution that could better
accommodate the higher torque requirements on their larger
models. The new electric clutches would replace existing
inconvenient, manually-operated clutches.
Solution:
Warner Electric engineers developed a modified SF-825 clutch
which allowed the equipment operators to remotely
engage/disengage either of two clutches (for the mixer and the
ejection pump) as needed. Unique input and output hubs were
developed to accommodate the two slightly different clutch
applications
• The clutch’s dynamic torque required 127 ft. lbs. at 1680 RPM,
and needed to be able to dynamically cycle the ejection pump.
• The mixer clutch had to handle breaking up mulch bales and
mixing the material with seed, fertilizer and water.

51. Fire Protection
Pumping Systems
Problem:
A leading global manufacturer of integrated pump solutions
needed a reliable coupling for use on its fire protection
packaged pumping systems installed in large commercial
buildings. The couplings connect large capacity pumps to
diesel drive engines. The challenges associated with this
application were that the space envelope between the pump
and engine was very small and the pump and engine were
positioned at different elevations creating misalignment
issues.
Solution:
After a detailed review of the specifications with the customer,
Ameridrives engineers recommended SC (short coupled)
universal joint driveshafts designed specifically for short
distance applications with significant misalignment.
• Available in lengths ranging from 9.5 in. to 22.25 in.

52. Underwater Mining Dredge
Problem:
A sand mining dredge required a 120 ft. long coupling drive
(longest ever built) to connect a 600HP motor to a suction
pump operating at the bottom of an underwater sand mine.
Solution:
TB Wood’s engineers designed a custom hub with unique
flange disc pack and tapered bushing mounting
• Six modified Form-Flex couplings were connected to form
the 120 ft. drive train
• Design allows for easy field service and axial adjustment of
the pump impeller
• Couplings were selected due to superior capacity to handle
parallel offset and angular misalignment
• Units designed to operate in a harsh environment with low
maintenance for 40 years
