液压驱动功能驱动与泵通过9v直流远程控制通信。这确保了安全性,并消除了需要电线之间的泵和驱动器,其他制造商提供。沉默在使用。相比之下,电动和气动胀管系统噪声较大。结构紧凑,便于在锅炉桶内使用。兼容性-相同的powerpack为所有4个驱动器扩展5/8 "外径到4 "外径管。非常高的扭矩开发-可以很容易地扩大大直径,厚壁管厚管板。长寿命+低维护。锅炉安装在创纪录的时间内完成。可长时间使用,因为驾驶不受高温影响。 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
