Power Transmission Quick and precise fastening for larger shafts 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.
