1P108931 Power End Crankshaft for SPM QWS1000 Frac Pump

描述

Frac Plunger Pump Crankshaft 1P108931 For QWS1000

Our QWS1000 crankshafts are high-performance forged power end components specifically engineered for Weir SPM QWS1000 triplex plunger frac pumps, widely used in oilfield fracturing, acidizing, and cementing operations. As the core transmission part of the pump, they convert rotary motion into reciprocating plunger movement, directly affecting the pump’s stability and output efficiency.

Manufactured from premium AISI 4140 alloy steel via one-piece forging, each QWS1000 crankshaft undergoes strict heat treatment, stress relief, and precision machining. This ensures exceptional fatigue strength and torsional resistance to withstand the extreme combined bending and torsion loads of continuous high-pressure pumping in harsh oilfield environments.

Fully interchangeable with OEM specifications, our QWS1000 crankshafts feature optimized journal geometry and internal lubrication passages. These designs reduce stress concentration, minimize wear, extend service life, and help operators reduce downtime and maintenance costs for their QWS1000 frac pumps.
