Who is Deublin and what does it make?
Deublin is an American manufacturer with 80 years of experience in rotary unions and electrical slip rings, used to transfer fluids to rotating components. The range covers different media — water, hydraulic oil, thermal oil, steam, air and multi-media combinations — through series dedicated to each application, from compact low-capacity units (series 1115) to very high-pressure models (series ZAP, up to 1,100 bar). For customers in Romania we can bring in individual unions from these series, based on the full code on the label of the existing unit.
The difference between the series comes down to the combination of pressure, speed and medium: the general-purpose series (57, 755, 6200-6400) allow the seal to be replaced directly on the machine, the high-pressure series (927, AP, D, ZAP) are intended for high pressures, and series AP uses balanced seals with tungsten carbide, while series 54, for the food, chemical and pharmaceutical industries, is built from 316 stainless steel for corrosion resistance, and series 157 has a forged brass housing and a stainless steel rotor. Series 1115, intended for low-capacity applications, withstands up to 34.5 bar on hydraulic oil.
For rotating equipment in Romanian industry — machine tools, continuous process machinery, paper industry lines — Deublin covers the situations where an ordinary rotary union cannot withstand the combination of pressure, speed and medium handled.
What do we supply from the Deublin range?
| Product | Description |
|---|---|
| Series 1115 — low-capacity rotary unions | Family of single-passage, self-supported rotary unions 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, withstands pressures of up to 34.5 bar on hydraulic oil. The full code, for example 1115-000-001, indicates the rotor connection type and the supply connection type. For a quotation, send the code from the label or the connection type, the working pressure and the medium handled. |
| High-pressure series — 927, AP, D, ZAP | Family of unions for applications with high pressure, speed and precision requirements at the same time. Series 927 is designed for high pressure and speed with low friction torque, series AP uses balanced seals with tungsten carbide, series D accepts angular movement at very high pressure, and series ZAP reaches 1,100 bar. Frequently used in rotating hydraulic machinery and continuous process equipment where a standard unit cannot withstand the load. |
| Series for the food and pharmaceutical industries — 54, 157 | Rotary unions for media in the food, chemical and pharmaceutical industries. Series 54 is built from 316 stainless steel, for corrosion resistance even at high temperatures, and series 157 covers smaller 1/2 inch units, with a forged brass housing and a stainless steel rotor. They are used on rotating equipment in processing lines where contact with the fluid must use materials compatible with the food product. |
Why Deublin?
- Series dedicated to each medium — water, hydraulic oil, thermal oil, steam, air and multi-media combinations, with no compromise on sealing
- High-pressure series (series AP with balanced tungsten carbide seals), up to 1,100 bar for series ZAP
- Series 54 in 316 stainless steel for the food, chemical and pharmaceutical industries, corrosion resistant
- Seal that is easy to replace directly on the machine in the general-purpose series, without fully dismantling the unit

How do we supply Deublin in Romania?
We bring in Deublin unions from series 1115, the high-pressure series and those for the food industry to order from the European Union, usually within 1–4 weeks. We rely on the manufacturer's technical documentation to identify the correct variant: for each request we check the full code on the label of the existing union or, if it is missing, the rotor connection type, the medium handled, the working pressure and the approximate speed in the installation. We have no information of our own on the Deublin stock available at any given time, and the lead time depends on confirmation of the exact code with the manufacturer. Please send us a photo of the label, if possible, for quick identification.
We do not size the application (maximum permitted speed, axial load on the bearing); we supply the union according to the code confirmed by the customer.
Frequently asked questions about Deublin
What products does Deublin manufacture?
Deublin manufactures rotary unions and electrical slip rings, used to transfer water, hydraulic oil, thermal oil, steam or air to rotating components. The range includes general-purpose series, high-pressure series and stainless steel series for the food and pharmaceutical industries.
What do I need to send for a quotation on a Deublin union?
The full code from the label of the existing union, for example 1115-000-001. If it is no longer legible, we need the rotor connection type, the supply connection type, the medium handled and the maximum working pressure in the installation.
Do you supply Deublin products in Romania and how quickly?
Yes, we bring in Deublin unions to order from the European Union, usually within 1–4 weeks of code confirmation. The lead time depends on the exact availability of the requested variant with the manufacturer.
What do we specify in the quotation for Deublin unions?
We do not confirm from the product documentation the maximum permitted speed for each variant or the axial load on the bearing; these are checked individually against the manufacturer's application documentation before the final quotation is sent to the customer.
How do I request a Deublin quotation?
Send the Deublin code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
