oil pump / plunger / multi-stage / heavy-duty

Weir SPM's Destiny? TWS 2500 features a 2500 horsepower rating
with 273.000 lb of rod load and a 10" stroke. It is designed to withstand
even the most harshest conditions involved with multistage frac applications.
This design features a higher durability as it uses a longer stroke, thus
lowering the number of needed cycles when compared to an 8" stroke
quintuplex pump.
These features allow for more operating ranges then those available to
other triplex pumps.
