SSY004935985 Main pump front diaphragm Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004935985 main pump front baffle is a genuine SANY hydraulic main pump protective accessory, widely compatible with SANY excavators, pump trucks, truck-mounted pumps, loaders, and other construction machinery. Installed at the core front end of the hydraulic main pump, it primarily serves to prevent dust and contamination at the pump body’s front end, provide cushioning and impact protection, dampen vibrations, limit movement, and regulate airflow. It effectively protects the main pump’s precision oil circuits, bearings, and sealing components, making it a core original accessory ensuring stable operation of the hydraulic system.
This main pump front baffle is specifically optimized for the main pump’s front-end protection system. It effectively shields the precision components at the front of the main pump, preventing mud, dust, oil, and metal shavings from entering the pump body. Simultaneously, it buffers high-frequency vibrations generated during equipment operation and impacts from external objects, preventing wear and damage to the pump’s front end. Construction machinery operates under harsh conditions such as mining, infrastructure, and heavy earthmoving. Ordinary baffles are prone to deformation, corrosion, cracking, and poor fit, easily leading to main pump blockage, oil circuit wear, abnormal pump noise, and hydraulic power loss. This product uses Sany’s original one-piece stamping process, resulting in a robust and rigid overall structure that is resistant to deformation and warping. It meets the original manufacturer’s stringent quality control standards. Standard mounting holes allow for non-destructive replacement of old and failed parts. It is suitable for routine equipment maintenance, fault repair, new machine assembly, and bulk stocking, effectively reducing the probability of main pump failure and overall machine maintenance costs.
