Double gear pump and single pump selection comparison

The application of double gear pump and single pump in hydraulic system is different, and each has unique advantages. The following is a comparative analysis of the two to help customers better choose the right pump type:

1. Structure and design
   Single pump: only one pump core, the design is relatively simple, suitable for a single working condition of the hydraulic system.
   Double gear pump: Composed of two gear pumps, each pump core can operate independently or in combination, suitable for systems requiring multiple pressure outputs.
2. Application scenario
   Single pump: suitable for equipment with single pressure and flow requirements, such as simple hydraulic systems in construction machinery.
   Dual pump: suitable for applications requiring flexible control, such as hydraulic systems that need to achieve different actions; It is widely used in equipment requiring multi-loop control, such as forklifts and excavators.
3. Efficiency and control
   Single pump: simple operation, high efficiency, mainly suitable for hydraulic systems that do not require complex control.
   Dual pump: Through the combination of different flow and pressure of the pump core, you can flexibly control a variety of working conditions, improve the efficiency of the overall system and operational flexibility.
4. Cost and maintenance
   Single pump: simple structure, relatively low manufacturing and maintenance costs.
   Dual pump: The structure is more complex, the cost and maintenance costs are slightly higher, but it has greater advantages in functionality and flexibility, and is suitable for applications with high control accuracy requirements.
5. Performance
   Single pump: stable operation under single flow and pressure requirements.
   Dual pumps: Different pressure or flow combinations can be achieved to optimize system performance and reduce energy waste.
   conclusion
   If the customer’s hydraulic system requirements are simple, and the cost control is more strict, you can choose a single pump.
   If the customer needs to achieve multi-function operation in a hydraulic system, or needs to supply different flow and pressure at the same time, it is recommended to use dual gear pumps to meet diverse needs.
