Small Tips
How to Choose an Excavator Hydraulic Pump
1. Machine Specifications and Requirements
-
| - Excavator Model and Size: The pump must match the size and power of your excavator (e.g., mini, mid-size, large). | |
| - Original Pump Specifications: Check the model number, displacement, max pressure, and mounting flange of the original pump. This is the most direct reference. | |
| - System Pressure (Bar/PSI): The new pump must withstand the hydraulic system's maximum working pressure and peak pressure. | |
| - Flow Rate (L/min or GPM): The pump's flow rate determines the speed of hydraulic cylinders and motors. It must meet the machine's performance needs. |
01
| 2. Pump Type | |
| - Gear Pumps: Cost-effective, robust, simple structure. Common in mini and mid-size excavators. Slightly less efficient. | |
| - Piston Pumps: High efficiency, high pressure capability, good variable displacement control. Used in most modern mid to large excavators for better control and fuel efficiency. | |
| - Vane Pumps: Smooth operation, medium pressure. Less common in modern excavators |
02
| 3. Compatibility | |
| - Mounting Flange and Spline/Shaft: The physical connection to the engine must match perfectly. Incorrect splines can destroy the pump or engine. | |
| - Port Size and Thread Type: The inlet and outlet ports must match your hydraulic hose fittings. | |
| - Electrical Connectors (for electronic pumps): If it's a variable displacement pump with electronic control, the connectors must be compatible. |
03
| 4. Quality and Brand | |
| - OEM (Original Equipment Manufacturer): Highest quality, perfect fit, but most expensive. (e.g., Kawasaki, Bosch Rexroth, Linde, Parker) | |
| - Aftermarket Quality: Reliable aftermarket brands can offer a good balance of quality and price. Ensure they have good reviews and warranties. | |
| - Remanufactured Pumps: A cost-effective option if the core is in good condition and rebuilt by a professional shop. |
