DN25 Deublin rotary joint alternative products

DEUBLIN's joints are used in almost infinitely wide areas, widely applicable to various materials, viscosity, temperature, pressure and speed applications. The rotary joint is a unique and specialized product because it must be able to withstand very high pressure while rotating at very high speeds. To achieve this, it is necessary to achieve a nearly perfect fit of the sealing surface, that is, the seal must be slightly overlapped, regardless of the pressure factor of the medium, and the load or pressure on the sealing surface is kept at a low limit and smooth Rotate steadily and reduce friction to a low limit to extend service life and ensure no leakage.

Deublin 55 series universal rotary joint This small universal joint can be used for water, intermittent steam or hot oil applications. Two high-precision ball bearings keep the sealing surfaces in precise alignment. 55, 155, 255 and 355 models have stainless steel swivels. Models 525, 555 and 655 have carbon steel swivels. All specifications of the joints are available in dual-channel and single-channel, and both adopt double-sealing combinations. "Universal" seal The standard general-purpose seal is made of graphite to copper and has a tetrafluoroethylene sealing wedge. It can be used for water, intermittent saturated steam (less than 20% of the time) or hot oil applications requiring low torque, temperature not exceeding 395 ℉ (220 ℃) and filtration accuracy of about 25 microns. When the application temperature of the joint exceeds 250 ℉, periodic lubrication is required. Please consult the Dubrin Engineering Department for lubrication guidelines. Hot oil application type joints require lubrication with suitable high temperature lubricants. Extended life seal (E.L.S.) For applications that cannot be filtered and the water may contain rust, chips, and debris; or when a longer service life is required for the joint, an extended-life seal can be used to extend its life by 2-4 times or even according to specific conditions. Extended to longer. This type of joint has tungsten carbide-to-ceramic and O-ring seals with fluororubber materials.
