SSY004935960 Main pump rear diaphragm Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004935960 main pump rear baffle is a genuine SANY hydraulic protection accessory, compatible with SANY excavators, pump trucks, truck-mounted pumps, loaders, and other construction machinery. Installed at the rear of the hydraulic main pump, it primarily serves for rear-end isolation and protection, dust and contamination prevention, vibration reduction and noise reduction, and structural regularization. It effectively protects the precision components at the rear of the main pump, isolates impurities and airflow interference, prevents contamination and wear on the pump, and ensures stable operation of the hydraulic main pump.
This product effectively prevents dust, mud, and iron filings from entering the main pump tail section, reducing component contamination, jamming, wear and tear, and abnormal equipment noise. Equipment operating under heavy loads in mines, construction sites, and other environments is prone to deformation, corrosion, and poor fit with ordinary baffles, leading to dust ingress into the main pump, oil line buildup, abnormal pump noise, and power loss. This product uses original factory one-piece stamping technology, ensuring high rigidity and resistance to deformation. It meets Sany’s quality inspection standards, and standard holes allow for non-destructive replacement of older parts. Suitable for equipment maintenance, fault repair, and bulk stocking, it effectively reduces the probability of main pump failure and maintenance costs.
