Benefits and features
ETP-HYDROPRESS®
ETP-HYDROPRESS is a hydraulic joint, which
consists of a double-walled steel sleeve. Mounting is
easily carried out with a hydraulic grease pump. In the
flange there are two connections: a grease nipple for
the pump, and a pressure release valve used for
dismantling, a screw which presses against a steelball
and forms a spherical seating. Radial and/or axial
connections for the pump hoses are possible. The
inner diameter can be made with spiral tracks in order
to easier let foreign liquids or particles disappear.
When the hydraulic pressure from the pump is
injected, the double-walled sleeve expands uniformly
against shaft and hub and along the shaft and forms
a rigid joint. When dismantling, the allen screw in the
pressure release valve is loosened and the grease
comes out. ETP-HYDROPRESS returns to its original
measurements and the joint is loose. Normal working
pressure is up to 700 bar.
• Variable transmittable torque or axial force
by changing the mounting pressure.
• Easy mounting/dismantling of large
components in tight spaces.
• Quick mounting. Only a grease pump is
necessary for mounting.
• Radial and axial connection is possible.
• Fine adjustments of the hub can be made
when mounting.
• Good concentricity, also after several mountings.
