2A113295 2P111511 Power End Crankshaft for SPM QWS2500 Frac Pump

QWS2500 crankshafts are essential power end spare parts designed for Weir SPM QWS2500 triplex plunger frac pump. As core forged transmission components, they play a vital role in converting rotary motion into plunger reciprocating movement for oilfield fracturing, acidizing and cementing operations. Made of premium AISI 4140 alloy steel through integral forging and precise heat treatment, our QWS2500 crankshafts deliver outstanding fatigue strength, torsion resistance and stable performance under high-pressure heavy-duty working conditions. Common OEM part numbers 2A113295 and 2P111511 are fully interchangeable with original parts, perfect for replacement and maintenance of SPM QWS2500 frac pump. With strict dimensional inspection and fine surface finishing, these crankshafts effectively reduce stress concentration, extend service life and support reliable long-term operation in harsh oilfield environments.
