Meet the challenges of high temperatures with a simple component but designed to last
In the chemical, pharmaceutical, plastics and printing industries, applications requiring the use of high-temperature diathermic oil are becoming increasingly common.
But how to ensure safety, operational continuity and low maintenance requirements?
The answer lies in choosing the right rotary joint.
The Z-series rotary joint was developed precisely to meet these critical needs. Thanks to its design and high-quality materials, it is a reliable, efficient and durable solution even under extreme conditions. The Z rotary joint is distinguished by its thermal and mechanical resistance, making it ideal for applications with diathermic oil up to 300°C and a maximum rotational speed of 500 rpm.
What our Z rotary joint looks like
- Cast iron body: ensures strength and durability even in harsh industrial environments.
- Antimony-impregnated graphite seal ring: ensures a perfect seal even at high temperatures and pressures.
- Graphite inner bushings: minimize wear and ensure smooth operation over time.
- Compressed carbon fiber gasket: high sealing and thermal efficiency.
Available configurations:
- Single passage
- Double pass with rotating siphon
- Double passage with fixed siphon
Sizes available:
(nominal rotor diameter)
- - 19 mm or 3/4”
- - 25 mm or 1”
- - 31 mm or 1 ¼”
- - 38 mm or 1 ½”
- - 50 mm or 2”
- - 64 mm or 2 ½”
Connections for every need:
- Right or left hand threads (BSP ISO228 standard)
- Quick-release flange versions
Application areas: when to choose the Z-joint
The Z-joint is an ideal choice for industries that need precise and reliable thermal control in high temperature diathermic oile environments.
Its features make it particularly suitable for:
- Chemical industry: where safety is a priority and fluids must be transferred with absolute tightness.
- Pharmaceutical industry: where processes must be stable and controllable under all conditions.
- Plastics and rubber: for high repetitive thermal cycles.
- Printing / Converting / Flexo: where temperature control is critical for final product quality.
Low maintenance and long service life: the practical advantages
One of the main advantages of the Z series is low maintenance due to its modular design and high quality materials. A complete ready-to-use repair kit, consisting of:
- - Spring
- - Graphite bearing
- - Locking pin
- - Graphite seal
- - Flat gasket
- - Support bush
- - Seeger
This extends joint life, reduces downtime costs, and improves overall plant productivity.
An investment that makes a difference
Choosing the Z rotary joint means banking on a reliable, versatile component designed for complex industrial environments. The combination of advanced materials, customizable configurations and ease of maintenance make it an ideal solution for any plant operating with diathermic oil at high temperatures.
