Deublin 2440-001-306254 Rotary Union Alternative | Embedded Stainless Steel Swivel Joint

Description

Deublin 2440-001-306254 Rotary Union – High-Performance Domestic Alternative Solution

As a cost-effective and reliable domestic alternative to the Deublin 2440-001-306254 rotary union, our embedded-type stainless steel rotary union is engineered to meet the demanding requirements of continuous casting machines, metallurgy mixers, and heavy-duty rotating equipment.

Designed for continuous operation, high stability, and long service life, this rotary union ensures leak-free media transfer between stationary supply lines and rotating shafts, even under harsh metallurgical working conditions.

Product Overview

The Embedded Type Stainless Steel Rotary Union is a self-supported, in-the-shaft-mounted swivel joint that supports both monoflow and duoflow configurations, making it suitable for complex fluid circulation systems in metallurgical and continuous casting applications.

By combining balanced mechanical seal technology, engineered sleeve bearings, and full-media flow design, this rotary union delivers stable performance, reduced maintenance frequency, and excellent lifecycle cost control.

This product is widely used as a direct replacement for Deublin 2440 series rotary unions, offering equivalent performance with shorter lead times and significant cost advantages.

Key Product Features

Monoflow and Duoflow Design

• Supports single-flow (monoflow) and dual-flow (duoflow) media transfer

• Ideal for cooling, heating, or lubrication circuits in metallurgy mixers and casting equipment

• Flexible system integration for complex process control

In-the-Shaft Mounted Embedded Structure

• Embedded installation inside the shaft saves axial space

• Enhances system compactness and mechanical stability

• Particularly suitable for continuous casting machines and rotating mixers

Self-Supported Rotating Union

• Equipped with an engineered sleeve bearing

• Does not rely on external support structures

• Effectively absorbs internal loads generated during rotation

Flexible Mounting Options
