Hydraulic Tube Expansion Systems (Hydex)
Hydraulic Drives
Features
- Drive communicates with the pump via 9v DC remote control. This ensures safety and eliminates the need of electrical cord between pump and drive that other manufacturers provide.
- Silent during use. In comparison electric and pneumatic tube expansion systems are noisy.
- Compact, therefore easy to use inside boiler drums.
- Compatibility - Same powerpack for all the 4 drives to expand 5/8” o.d to 4” o.d tube.
- Very High Torque Developed - can expand large diameter, thick wall tubes in thick tube sheets easily.
- Long life + low maintenance.
- Boiler erections get completed in record time.
- Can be use for long working hours because drive is unaffected by heat.
- Dual drive powerpack is available to connect 2 drives to a single powerpack to cut down tube expansion time cycle by a further 50%.
- Microprocessor controls on the pump automate the expansion cycle. Trip, pause and reverse times for the drive are adjustable.
- No need for repeated manual STOP/START of the drive during the expansion cycle - completely automatically
