Hollow shaft electric motors for pressure washer pumps
Soga Hollow Shaft Electric Motors Hollow Shaft Single And Three Phase Motors
HS electric motors are specialized motors designed for direct coupling to pressure washer pumps. Featuring IP54 protection, these motors are available in single and three-phase configurations with power up to 11 kW. The hollow shaft design with its appropriate flange allows for quick and easy installation, enabling direct mounting to the pump in just a few minutes without the need to disassemble the motor front side. This design provides efficient power transfer and simplified maintenance, making them ideal for professional cleaning applications.
Hollow shaft electric motors 4 poles, on frames 90-100, for direct mounting to pressure washer pumps:
Hollow shaft single-phase motors
4-pole motors (1.5-2.2 kW, S3 75%) designed for pressure washer pumps. Operating at 220V/50Hz with F insulation class and IP54 protection. Available in IEC frames 90LA, 90LB, 90LC, and 100LB. Features direct-drive coupling system allowing fast mounting to pumps without disassembling the motor front side. Simply align the hollow shaft with its dedicated flange for quick, secure installation.
Hollow shaft three-phase motors
Industrial-grade hollow shaft motors designed specifically for pressure washer applications. These 4-pole motors operate at 230/400V/50Hz with F insulation class and IP54 protection. Delivering 2.2-11 kW power (S6 75%) at 1400-1450 rpm, they provide reliable performance for demanding cleaning systems. The innovative hollow shaft design allows direct coupling to pumps without disassembling the motor front side—simply align with the appropriate flange for quick, secure installation in minutes.
