Jabsco Hy-Line lobe pumps are often used in applications with high hygiene and cleaning requirements, which place corresponding demands on the sealing solutions used. Lobe pumps are used in hygiene-critical processes where gentle product handling and high operational reliability are essential – for example in the food, dairy, pharmaceutical and cosmetics industries. They are particularly suitable for viscous and sensitive media such as yoghurt, sauces and creams, but are also used for more challenging products. The pumps can also handle more solid media such as pieces of fruit and meat, while being able to cope with abrasive products and aggressive liquids.  

We offer a mechanical seal that fits directly onto the Jabsco Hy-Line Lobe series and meets the requirements for operational reliability, chemical resistance and long service life – even with frequent CIP cleaning. 

Mechanical seals play an important role in ensuring leak-free operation and protecting both the product and the equipment from contamination. In rotating process equipment – such as lobe pumps – the seal prevents the medium from escaping around the axle, where there is movement between stationary and rotating components. 

In hygiene-critical industries such as the food, pharmaceutical and cosmetics industries, the sealing solution is crucial for maintaining cleanliness standards and avoiding downtime. At the same time, the seal must be able to withstand high temperatures, cleaning agents and pressure. 

The right mechanical seal not only contributes to stable and efficient production, but also extends the service life of the entire process equipment. 

Jabsco Hy-Line Lobe is a single-acting, internal mechanical seal developed specifically for Jabsco Hy-Line Lobe pumps. It acts as a direct replacement for the original seal and can be installed without the need for modifications. 

The rotating part and the stationary part are available in silicon carbide (SIC) or tungsten carbide. 

The seal is supplemented with an O-ring in EPDM, NBR or Viton® (FKM), depending on the technical application and the requirements for temperature and chemical resistance. The gasket is suitable for CIP cleaning procedures and designed for long service life and minimal risk of leakage during continuous operation. 

With over 40 years of experience, we advise on the selection of mechanical seals for process equipment in demanding industries. The solution is manufactured to OEM specifications and can be installed directly in Jabsco Hy-Line lobe pumps without the need for modifications. 

No. The seal has been specially developed for Jabsco Hy-Line lobe pumps and is therefore not suitable for other pump types in the Hy-Line series.

The rotating and stationary parts are available in either silicon carbide (SiC) or tungsten carbide (Tc), depending on wear and process requirements. The gasket is supplemented with an o-ring in either EPDM, NBR or Viton® (FKM), depending on the chemical composition and temperature of the medium.

Yes. It is suitable for CIP and designed to withstand high temperatures and aggressive cleaning agents.

Yes. We can provide certificates and documentation as required – e.g. for use in audits or quality assurance.
