XCMG Hydraulic Pump Seal Kit The excavator hydraulic pump is the core component of the excavator hydraulic system, and its performance directly affects the working efficiency and stability of the excavator. When purchasing hydraulic pumps for excavators, attention should be paid to the following aspects: 1. Brand selection: Choose a well-known brand of hydraulic pump, which ensures the brand's reputation and quality, and provides more reliable after-sales service. Common hydraulic pump brands include Caterpillar, Lovol, Hitachi, etc. 2. Flow and pressure: Select the appropriate flow and pressure according to the working requirements of the excavator. The flow rate determines the working efficiency of the hydraulic pump, and the pressure determines the stability of the hydraulic system. Select the appropriate flow and pressure range based on the model and working environment of the excavator. 3. Adaptability: The hydraulic pump needs to be compatible with the hydraulic system of the excavator, including connection methods, dimensions, etc. When selecting a hydraulic pump, it is necessary to ensure that it is fully compatible with the hydraulic system of the excavator to ensure normal operation. 4. Durability and reliability: Excavators are heavy equipment with harsh working environments, requiring high durability and reliability of hydraulic pumps. Choosing a hydraulic pump with good durability and reliable quality can reduce the occurrence of faults and improve the working efficiency of excavators. 5. Price and cost-effectiveness: The price of hydraulic pumps varies depending on factors such as brand, model, and performance. When selecting hydraulic pumps, it is necessary to consider both price and performance comprehensively, and choose products with higher cost-effectiveness. 6. After sales service: The repair and maintenance of excavator hydraulic pumps require professional technical support and after-sales service. Choosing a supplier with good after-sales service can promptly solve hydraulic pump faults and problems, ensuring the normal operation of the excavator. In short, choosing a suitable brand, suitable flow rate and pressure, good adaptability, high durability and reliability, reasonable price, and good after-sales service hydraulic pump can ensure the normal and efficient operation of the excavator.
