CAT12G hydraulic pump parts Description
The CAT12G hydraulic pump uses a series of precision components, and replacement or repair kits typically include piston assemblies, cylinder blocks, valve plates, drive shafts, retainer plates, thrust plates, seals, and other essential parts for maintenance or rebuilding
- Cylinder Block / Barrel: Houses the pistons and provides the main chamber for hydraulic fluid displacement.
- Pistons / Piston Shoes: Usually 9 pistons per pump, responsible for converting mechanical power into hydraulic motion.
- Valve Plate / Port Plate: Directs the flow of hydraulic fluid and maintains proper pressure within the pump system.
- Drive Shaft: Transfers mechanical rotation from the engine or motor to the pump's internal components.
- Retainer Plate (Set Plate): Keeps pistons in proper alignment within the cylinder block.
- Thrust Plate / Shoe Plate: Supports the pistons and absorbs axial loads within the rotating group.
- Bearings, Snap Rings, Springs, Washers: Additional components necessary for the smooth operation and securing of moving parts.
- Seal Kits, Gaskets, O-Rings: Prevent fluid leakage and maintain pump pressure and efficiency.
