Product Description
The part number 391-2883-119 refers to a high-pressure shaft lip seal (oil seal) that can be used in various hydraulic gear pumps and motors.
The defining characteristics of this component relate to its physical properties, material composition, and intended industrial application:
| Characteristic | Description |
|---|---|
| Part Function | It is an oil seal or lip seal that creates a robust seal between the rotating input/output shaft and the stationary pump or motor housing. |
| Application Specificity | Designed as a direct replacement part for numerous Parker Hannifin/Commercial Intertech hydraulic pumps and motors, including the M20, M30, M31, M330, P30, P31, P50, P51, and G101 series. |
| Durability & Material | Typically made from highly durable, industrial-grade materials, such as PTFE (polytetrafluoroethylene), selected for its resistance to high temperatures, hydraulic fluids, friction, and operational wear. |
| High-Pressure Capability | Engineered to withstand the high operating pressures common in heavy industrial hydraulic systems, unlike standard, lower-pressure seals. |
| Precision Dimensions | The seal features precise internal dimensions to ensure a secure, pressure-resistant fit: |
| Shaft Diameter (ID): 1.0625 inches (1 1/16") | |
| Outer Diameter (OD): Approx. 1.75 inches | |
| Width/Height: Approx. 0.33 inches | |
| Cross-Reference Number | This specific size and design is often cross-referenced with the internal manufacturer part number X73-50-9. |
Hydraulic Pumps & Motors: It is a key replacement part for many Parker/Commercial Intertech models, including the M20, M30, M31, M330, P30, P31, P50, P51, and G101 series pumps and motors.
Heavy Machinery: The seal is used in the maintenance of heavy equipment where these hydraulic pumps are installed, such as concrete pump trucks, excavators, agricultural machinery, and various engineering vehicles.
Function: Its purpose is to prevent internal hydraulic fluid leakage from the pump housing while simultaneously protecting the internal components from external contaminants, thereby extending the operational lifespan and efficiency of the machinery.
Gear pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
All Gear pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
