Excavator Hydraulic Main Pump

ELEPHANT FLUID POWER is a company specializing in the manufacture of hydraulic components for construction machinery. Its main products include Excavator Hydraulic Main Pump, which is widely used in the fields of construction, mining and heavy equipment. The following is key information about the company and its hydraulic main pump:

1. Company Background

Main business: Design, production and sales of high-pressure hydraulic pumps, motors, valves and other components, focusing on hydraulic system solutions for construction machinery (such as excavators and loaders).

Technical features: May provide gear pumps, plunger pumps (such as axial piston variable pumps), etc., adapted to mainstream brand excavators (such as Carter, Komatsu, Hyundai, etc.).

Market positioning: Some Chinese hydraulic companies replace international brands (such as Rexroth, Kawasaki, Danfoss) with high cost performance.

2. Key parameters of hydraulic main pump (taking a typical excavator pump as an example)

Type: variable axial piston pump (such as A10VSO series similar design).

Working pressure: 30-35MPa (high-pressure models can reach more than 40MPa).

Displacement range: Common 20-250cc/rev, suitable for excavators of different tonnages.

Control mode: load sensitive (LS), pressure compensation (PC) or electro-hydraulic proportional control.

3. Application and adaptation

Compatibility: Pumps suitable for various brands and models may be provided, and the specific model needs to be confirmed (for example: replacing Kawasaki K3V/K5V series).

Typical faults: internal leakage, insufficient pressure, high noise, etc., which are related to seal wear or port plate damage.

4. Procurement and service suggestions

Confirm the model: The displacement, pressure, installation size and control method of the original pump need to be matched.

Alternative solution: If it is a domestic pump, the durability and flow curve compatibility need to be verified.

After-sales service: Ask about the warranty period and technical support (such as on-site commissioning).
