1、Precision die-cast aluminum alloy crankcase with better strength, and surface oxidation treatment is applied to prevent surface oxidation. The crankshaft is precision forged from high-strength alloy steel to ensure sufficient material strength. The plunger is made of high-performance tungsten steel, which has high hardness, wear resistance, heat resistance, and corrosion resistance, ensuring reliable material performance.

2、The connecting rod uses precision forged aluminum alloy, combined with dedicated connecting rod bronze bushings and bearing shells, making the connecting rod more wear-resistant and better lubricated. Bearings are selected as tapered roller bearings, which have greater load capacity and quieter operation compared to ordinary bearings, resulting in longer pump life.

3、The pump body is made of high-strength alloy steel precision forged. Customized packing water seal provides excellent wear resistance, heat resistance, and fatigue resistance. The unidirectional valve structure has been redesigned and uses special alloy steel unidirectional valve disc and seat, offering better impact resistance, wear resistance, and fatigue resistance.
