Based on the provided reference, the maximum working pressure for the described hydraulic gear pump is 200 bar (2,900 psi).
Understanding Hydraulic Gear Pump Pressure
Hydraulic gear pumps are commonly used in fluid power systems for their simplicity and reliability. The pressure they can withstand is crucial for system performance and safety. The maximum working pressure is determined by the design, materials, and construction of the pump components.
Key Specifications from the Reference
The reference provides specific details about the construction materials and the resulting maximum working pressure:
- Materials:
- Pump body: Special aluminium alloys
- Covers: High-grade cast iron (designed to avoid deformation at high pressure)
- Maximum Working Pressure: 200 bar (2,900 psi)
- Maximum Speed: 3000 rpm
These materials and design choices are specifically implemented to enable the pump to operate effectively and resist deformation under high-pressure conditions.
Pressure Rating in Context
A pressure rating of 200 bar (approximately 2900 psi) falls within the typical range for many standard external gear pumps used in mobile and industrial applications. Higher pressure capabilities often require more robust designs, advanced materials, and tighter manufacturing tolerances, which can increase cost and complexity.
Summary of Specifications
For clarity, here is a summary of the key specifications mentioned in the reference:
| Specification | Value |
|---|---|
| Maximum Working Pressure | 200 bar |
| Maximum Working Pressure | 2,900 psi |
| Maximum Speed | 3000 rpm |
| Body Material | Special aluminium alloys |
| Cover Material | High-grade cast iron |
This specific model, constructed with special aluminium alloys and high-grade cast iron covers, is rated to handle up to 200 bar (2,900 psi).
