TorqMax
Advanced-geometry pumping unit
APPLICATIONS
■■
■■
■■
■■
High-load wells that benefit from a fast
downstroke with a slower upstroke
Enhanced oil recovery well designs
such as steam fluids
Unconventional shale reservoirs
Oils wells with large variations
in production and load
■■
Automation applications
■■
Conventional oil wells
BENEFITS
■■
■■
■■
■■
Delivers easy installation and maintenance
Provides long service life of over 25 years
with proper maintenance
Lowers year-over-year operational cost
Enables downsizing the unit and prime mover
compared to conventional units, saving cost
initially and in day-to-day operations

■■
■■
Advanced geometry creating a larger
allowable load range and more
efficient operation
Phased crank design with more
torque available for the upstroke
High-load, easily serviced center bearing
based on proven railway bearing design
Dual-axis hinge pin style equalizer
bearing for long life and reduced stress
in assembly
High-capacity gear reducer designed
far beyond API requirements
Large, low-speed shaft for long life
and increased counterbalance support
Field-serviceable gear reducer design
with bolt-on cranks
Fully enclosed horsehead
for maximum strength
The TorqMax* advanced-geometry pumping unit is an alternative to conventional pumping units. For
certain rod pump applications, the TorqMax pumping unit can help reduce torque and lower prime
mover horsepower requirements, thus reducing lifting costs.
The primary differences between TorqMax pumping units and conventional units are:
■■
■■
■■
The structure of the TorqMax pumping unit is shifted forward from the gear reducer toward the
wellhead, whereas the center of the equalizer bearing shaft sits directly over the center of the
slow-speed shaft of the gear reducer on conventional pumping units
The crankpin holes are placed at an offset angle on the crank arm of the TorqMax pumping unit
but run parallel to the crank arm on a conventional unit
The TorqMax pumping unit must always rotate clockwise to maximize effects, while a conventional unit can run in either direction of rotation.
