Hydraulic Tube Expansion Systems from Sunex Engineers :
|
|
|
| |
The hydraulic pump supplied with hydraulic drive incorporates the latest state of the art of the art technology resulting in subcompact pump developing 100 bar pressure. The system is mounted on four wheels for on site manevourability.
Expansion of tube is regulated by adjusting pressure setting on pump. Once required amount of wall thinning is achieved the drive trips automatically.

Features:
- Hydraulic tube expansion drive communicates with power pack via 24 V DC control cable. This ensures safety and eliminates electrical Shock hazard making it most preferred expansion method.
- Low setup time and ease of operation.
- Compact design of Power pack and Drive.
- Interchangeable Tube expansion drive. Same power pack suitable for all 3 drives to expand ¾” OD to 4” OD tube.
- High consistency in wall thinning of expanded tubes through precision controls.
- Reverse phase protection eliminates wrong direction of electric motor.
- Boiler erections get completed in record time.
- Silent operation, compact design, long life & low maintenance.
