1P100080 Power End Crankshaft for TWS600S Frac Pump

描述

Frac Plunger Pump Crankshaft 1P100080 For TWS600S

The 1P100080 forged crankshaft is a core power end component engineered exclusively for the Weir SPM TWS600S triplex plunger frac pump, a 600BHP unit widely used in oilfield fracturing, acidizing and cementing operations.

Manufactured from premium AISI 4140 alloy steel via one-piece forging, this crankshaft undergoes strict heat treatment and stress relief to deliver exceptional fatigue strength and torsional resistance—critical for withstanding combined bending and torsion loads under extreme working conditions. Its precision-machined surfaces eliminate sharp edges, burrs and scratches, while optimized transition fillets and journal oil holes minimize stress concentration, the main cause of fatigue failure.

Validated by water hammer fatigue testing, the crankshaft delivers a reliable service life of approximately 500 operating hours, with enhanced resistance to torsional fatigue—the primary failure mode of high-power frac pump crankshafts. It features an integrated lubrication channel design, ensuring direct oil supply to connecting rod big-end bearings for reduced wear and prolonged service life.

As a professional manufacturer, YOU LONG PETRO adheres to strict OEM specifications and quality control standards. Each 1P100080 crankshaft is 100% inspected for dimensional accuracy and surface defects, ensuring perfect compatibility with TWS600S pumps and consistent performance in harsh oilfield environments.
