The SCHAAF HDE 4000-DM is an efficient, modular electrohydraulic high-pressure unit designed for mobile industrial applications.

• Highest power density due to direct pressure
  generation up to 4000 bar (no pressure intensifier!)
• Rugged, compact and durable design
• Constant pressure build-up without interruption
• Wide power range (0.75 – 3 kW, motor module)
• Supply voltage only 230V 1 phase (alt. 400V 3 phase)
• Electronic high-pressure regulation
• Electronic controlled pressure relief valve
• Remote control with multifunction display
• Active oil cooling and filtering (cooling module)
• Module compatible with application (in situ)
• All modules with quick lock (ready for immediate application)
• Small dimensions and low weight (< 20 Kg)
• Also suitable for hydraulic wrenches
• Additional designs see type code
  

The SCHAAF HDE 4000-DM is ideally suited for:

• The use of Bolt Tensioners (SSV), Hydraulic Nuts (HM),
  ExpaTen Bolts, GripLoc and ExpaHub
• Application with hydraulic screws
• Tightening and loosening of oil press fits
  (e.g. gearwheels, flywheels, coupling hubs,
  roller bearings, hydraulic couplings and
  overload protection devices)

All HDE 4000-D / DM are checked for material quality, dimensional accuracy, correct functioning and load-resistance. During order execution, they are
subject to continuous quality assurance measures and are supplied together with detailed technical documentation.

HDE 4000-D / DM are, of course, oil filled and ready for immediate use.

SCHAAF HDE 4000-D / DM are user-friendly, reliable, and manufactured in accordance with the highest level of technical know-how. Our highly-motivated
staff would be pleased to train your personnel, in situ or at our works, in the general handling and operation of high-pressure equipment.
