Mechanical seals are key components in processes where leak-free operation and high hygiene standards are essential. In food, dairy, pharmaceutical and chemical production, they protect both equipment and product from contamination and downtime. We offer tailor-made sealing solutions for INOXPA pumps that ensure optimal adaptation and long service life for your equipment. 

SLR is ideal for the food industry and is often used to handle high-viscosity products such as dairy products, curd, sauces and beverages. It is also suitable for filtration and bottling processes. Our mechanical seals for SLR are available in several material combinations, including carbon (Carbon), silicon carbide (SiC), tungsten carbide (TC) and stainless steel (SS). For demanding environments, we offer elastomers such as EPDM, NBR, Viton (FMQ) and PTFE.

Prolac is a hygienic centrifugal pump known for its easy maintenance and high performance. It is used primarily in the pharmaceutical and cosmetic industries, where sterile liquids place high demands on tightness and precision. The rotating part of the sealing system is typically made of silicon carbide (SiC), but is also available in carbon (CAR). The stationary part is available in stainless steel or SiC, and you can choose between EPDM, NBR or Viton (FKM) depending on the chemical resistance required in the application. 

EFI is a centrifugal pump designed for thin liquids such as water and is frequently used in food processing, especially for beer, wine and soft drinks, as well as in the chemical industry, where its AISI 316L steel construction makes it suitable for handling solvents and process liquids. 

We offer single-acting internal mechanical seals with rotating parts in ceramic (Cer), silicon carbide (SiC) and tungsten carbide (TC), which is an upgrade of the standard ceramic solution in new pumps. The stationary part is available in carbon (C) or tungsten carbide (TC), and the mechanical seal is supplemented with gaskets in EPDM, NBR or Viton (FKM), providing a stable and reliable solution. 

With more than 35 years of experience, we advise on the selection and adaptation of mechanical seals based on the technical requirements of the application and the properties of the media. Our wide range of combinations across types and materials makes it possible to achieve optimum chemical resistance, wear resistance and hygiene. This flexibility enables us to deliver reliable solutions that meet the requirements of even the most regulated industries, including food, pharmaceutical, cosmetics and chemicals. 

Our mechanical seals are manufactured to OEM specifications, ensuring a perfect fit for INOXPA equipment. They are designed for CIP cleaning, chemical resistance and compliance with hygiene requirements. We ensure that all components meet the relevant approvals and can be supplied with material certificates if required. 

The choice depends on the pump, the medium and the operating conditions. We will help you identify the right combination of materials and construction for your needs.

We select materials based on the application's requirements for pressure, temperature and media chemistry. Rotating parts are typically made of carbon, ceramic or SiC, while stationary components are most often made of stainless steel or SiC. For gaskets, we use elastomers such as EPDM, NBR, Viton® and PTFE – all to ensure maximum tightness and long service life under demanding conditions.

If you change the media type, temperature or cleaning routines, it may be necessary to upgrade your mechanical seal. We will be happy to advise you on alternatives that match your new requirements. 

You should inspect the mechanical seal regularly, replace O-rings and rotating parts when signs of wear appear, and follow the recommended intervals for cleaning and inspection.
