In a market still hungry for an adequate product,
ST9 has created a superlative one.

Truly great products arise from the point where respect for the fundamentals meets true innovation. The ST9 XGEN 2500 power end is an example of what can be achieved where others have failed. We saw “competitive” designs flex and crack, so we built ours stronger. Construction from wider webs and a beefier noseplate gives the XGEN 2500 no-nonsense rigidity. Advanced internal geometry with proprietary transverse reinforcement ensures our power end resists flexion under the heaviest abuse. The moving parts of the XGEN 2500 are equipped with bearings combining the highest technology and greatest load bearing area possible. All of this while fitting on a standard frac trailer.
