Deublin Series 1115
Deublin rotating union, series 1115, for air, hydraulic oil or vacuum, in low-capacity applications.
Series 1115 is a family of Deublin rotating unions with a monoflow, self-supporting design, used for transferring air, hydraulic oil or vacuum to low-capacity rotating components. The balanced mechanical seal, available in carbon-graphite/hardened steel or carbon-graphite/silicon carbide versions, supports pressures of up to 34.5 bar on hydraulic oil. The complete code of a unit, for example 1115-000-001, indicates the rotor connection type (UNF, NPT or metric) and the type of supply connection on the stationary side.
We bring in rotating unions from the 1115 series on order from the European Union, in 1–4 weeks, without stock from our own warehouse and without a public price. For a quotation, the customer sends the complete code from the label of the existing union, for example 1115-181-556, or, if it is missing, the rotor connection type and supply connection type, the working pressure and the medium handled. We confirm compatibility in the manufacturer's current catalogues before sending the quotation.

Frequently asked questions
What needs to be sent for a quotation on the 1115 series?
The complete code from the label of the existing union, for example 1115-000-001. If it is no longer legible, the rotor connection type, the supply connection type, the medium handled and the maximum working pressure in the installation are needed.
What do we check before quoting for the Deublin series?
The maximum speed permitted for each variant is checked case by case in the manufacturer's application documentation, before quoting.
We do not carry out application sizing (speed, axial force on the bearing); we supply the rotating union according to the code confirmed by the customer.
