The YTSY power end assembly is one of the most widely used pumps in the market and adopts reinforcement designs for complex domestic working conditions. The combination of a high-strength frame housing, integral forged connecting rod assembly, and top-class bearings significantly extends product life and reduces hydraulic pulsation for more stable operation during acidizing, continuous fracturing, and continuous high-pressure water injection .
