gas pump / plunger / service

The SPM® QWS 2500 XL frac pump, the latest generation of the SPM® QWS 2500, features frame design improvements for increased fatigue life.
As the industry continues to evolve, so do our pumps. The enhanced design of the SPM® QWS 2500 XL delivers extended service life and an increased rod load of 207,000 lbf even under the most challenging conditions of shale play operations.

The addition of a bolt-on bearing carrier protects the frame, pinion, and bull gear in the event the bearing clocks in the frame due to overload. This results in faster, more cost effective repair, keeping your assets in the field. Additionally, Weir engineering has evaluated and selected a larger Tier 1 bearing specifically for this application and optimised the lubrication through the bearing groove for a service life up to 4x longer than previous generation pinion bearings.

An updated frame design (patent pending) with improved geometry utilises advances in welding design and technology to significantly improve the fatigue life of the frame. The new design also includes blind tapped holes to reduce leakage. To validate these new features, Weir completed an endurance test of more than one million cycles at 107% rod load. The QWS 2500 XL passed the test and validated the increased rod load of 207,000 lbf.
