    • Flexible -Tolerance up to 1 mm (0.04”) of internal diameter
    • Quick - 4 - 6 extractions per minute
    • Economical - Low tool wear
    • High quality - No damage to hole in the tube-sheet

  • Set of service spanners
  • Pressure gauge
  • Instruction booklet
  • 2 (Two) hydraulic hoses:
    • Ø 9.5mm x 6m (Ø 3/8” x 19.7 ft)

ABTS

  • The ABTS (Anti-Breaking Tie-Rod System) allows the force with which the jaw penetrates the tube to be regulated to suit the tube’s diameter and the material of which it is made.
  • This device means the system is unaffected by the difference in inside diameter of, as much as 1 mm (0.04”), between tubes in the same sheet, preventing tie-rod breakage.

RC24

  • The RC24 remote control beside the knobs simplifies and speeds up stub extraction.
  • The remote control is fitted on both pneumatic and electric versions.

OPS

  • The electric OPS (Over Pressure Switch) cuts off hydraulic fluid delivery when the piston reaches the end of its stroke, preventing unnecessary overpressure in the system.

RSR

  • The RSR (revolving support ring) on which the Grippul is suspended during use allows optimal positioning in the tightest spaces.

Power Unit - TP10 / TP60 HDE

The Grippul puller is powered by either a semi-automatic electric or pneumatic hydraulic power unit.

  • TP10 - Portable semi-automatic hydraulic power unit available in the electric or pneumatic version
  • TP60-HDE- Evolution of the TP60-E power unit, the TP60-HDE stands out for its use in particularly demanding conditions.
    • Its special unique features and components make it an ideal partner for tube bundle maintenance professionals: Double pulling speed: preserves the TPM pulling spear and guarantees better functionality.
