Properties and Material Characteristics
High efficiency, long service life and reliable operation.
All-metal low-carbon stainless steel materials are used for the overcurrent parts, and the low-carbon stainless steel mainly composed of ferrite has excellent resistance to chloride stress corrosion cracking and higher mechanical strength.
The hydraulic friction loss is small, and the efficiency is more than 3% higher than that of the metal pump with the same parameters.
The geometric size of the all-metal pump is easy to control and guarantee, the surface finish of the parts is high, the fitting clearance of the parts is small, the volumetric efficiency is high, and the comprehensive efficiency is more than 5% higher than that of the non-metal pump.
The overcurrent components have a long service life, and the metal guard plate has a stronger ability to withstand shear sliding wear than ordinary non-metallic materials, and can withstand long-term shear wear.
The dynamic wear resistance is 0.008-0.08mm/year, the tensile strength is high, and it can maintain constant performance under long-term abrasive conditions.
