Product Description
Hollow Shaft Three Phase Motor — 5.5 kW, 400 V, 50 Hz for Washer Pumps
A hollow shaft motor engineered for high-pressure washer systems and direct-drive pump integration. The 5.5 kW, 230/440 V hollow shaft electric motor is designed for washing machine and pressure pump applications where compact, reliable power transmission is essential.
Why Hollow Shaft Motors Fit Direct-Drive Pump Systems
A hollow shaft induction motor is designed to support direct-drive pump integration between the motor and the pressure pump assembly. Compared with traditional coupling systems, the hollow shaft structure helps to:
- Reduce additional connection components
- Simplify motor alignment
- Optimize installation space
- Simplify assembly procedures
- Reduce long-term maintenance adjustments
This structure is increasingly used in:
- Pressure washer systems
- Booster pump units
- Industrial cleaning machines
- Compact pump assemblies
- OEM cleaning equipment
For equipment manufacturers requiring compact layouts, direct-drive configurations are often more suitable for modular equipment design.
How Key Specifications Affect Operational Stability
In industrial motor selection, long-term reliability is usually influenced by:
- Protection rating
- Insulation class
- Motor structure
- Cooling configuration
- Continuous-duty compatibility
HS112M2-4 Hollow Shaft Motor — Key Features
- Output: 7.5 HP / 5.5 kW
- Motor structure: 4-pole induction motor
- Protection rating: IP55
- Insulation class: Class F
- Housing: Aluminum
The IP55 protection structure helps reduce the impact of dust and water splashing in industrial cleaning environments. Meanwhile, Class F insulation supports stable operation during extended-duty cycles and higher thermal loads. For Southeast Asian industrial applications, these practical specifications are often more important than generalized "high-performance" claims.
Typical Industrial Applications
This hollow shaft electric motor is commonly used in:
- Industrial pressure washer systems
- Commercial cleaning equipment
- Booster pump assemblies
- Vehicle washing equipment
- Compact fluid transfer systems
- OEM pump drive machinery
In integrated pressure cleaning systems, direct-drive structures can also help simplify maintenance access and reduce coupling adjustment requirements.
