Leak-free operation with SSP-compatible sealing solutions

Mechanical seals play an essential role in the process industry, as they ensure leak-free operation in systems where sensitive media are handled under high pressure and changing temperatures. When it comes to SSP pumps, sealing solutions are required that can withstand aggressive cleaning agents while meeting the hygiene standards that characterise food and pharmaceutical production. SSP's rotary lobe pumps are used in precisely such environments, where a high degree of cleanliness and product safety are crucial. They are used for both delicate and viscous products such as sauces, creams and yoghurt, but also handle solid as fruit and meat pieces without compromising the product's structure. This places high demands on the material selection and construction of the seal, especially in terms of temperature tolerance, chemical resistance and mechanical wear resistance. It is also designed to withstand aggressive CIP cleaning and high loads over long periods of time.  

We offer solutions that are tailored to the construction of SSP pumps and ensure stable operation without unwanted interruptions. 

The 3 most popular models

SSP SR

The SSP SR mechanical seal is designed for pumps in the SR1 to SR6 series and has a robust construction with both wave spring and pressure spring. The rotating part is mounted with three screws, while the O-ring ensures tightness around the shaft. The choice of materials includes carbon or tungsten for the rotating part and stainless or tungsten for the stationary part. The combination of rubber in EPDM, NBR or Viton makes the seal flexible and resistant to a wide range of media. 

IBEX

The IBEX mechanical seal is designed for IBEX pumps and is intended for installations where the seal must be able to withstand high pressure and temperature fluctuations, making it an obvious choice in more demanding environments. Both the stationary and rotating parts are available in carbon, tungsten, silicon carbide and stainless steel, and can be combined across materials. The o-rings can also be adapted with materials such as EPDM, NBR or Viton®, depending on the liquid being handled. 

IBEX MOG

IBEX MOG has been developed for SSP pumps IBEX MOG 1 1/8‘, 1 3/8’, 2‘ & 3’ and is designed to operate in the most challenging process conditions. The choice of materials and construction are adapted to environments where hygiene, continuous operation and process stability are essential parameters. The rotating part is available in car, silicon carbide and tungsten, while the stationary part can be supplied in stainless steel, silicon carbide and tungsten depending on the medium, load and cleaning requirements. 

Important factors in the selection of a mechanical seal

brewery

When selecting the right mechanical seal for your SSP pump, it is important to consider the process conditions, the properties of the media and the cleaning requirements. The seal materials must be able to withstand mechanical stress, chemicals and high temperatures – often simultaneously. A quality solution must not only remain tight during operation, but also function stably during CIP processes, which are often an integral part of the cleaning regime. OEM compatibility is also a transparent advantage, as it ensures easy replacement without the need for equipment adaptation, which both saves time and reduces the risk of incorrect installation. 

Accessories for upgrading mechanical seals

It is rarely enough to simply replace the seal itself. To achieve an optimal and long-lasting solution, the associated accessories should also be considered. O-rings in alternative materials may be necessary to match specific process requirements, and in many cases documentation and material certificates are essential for auditing and quality assurance. We provide both advice and technical support to ensure you get a solution that is tailored to your needs – both technically and in terms of documentation. 

Frequently asked questions

man wondering

Which SSP models are compatible with the IBEX seal?

The IBEX seal is compatible with a range of SSP lobe pumps and can be used as a direct replacement in most installations without the need for modifications. 

Are these seals transparent to CIP?

Yes, all models mentioned are designed for hygienic operation and can withstand both high temperatures and chemicals from CIP cleaning. 

Are material certificates and approvals available?

Yes, we can provide documentation on materials, approvals and technical specifications on request – also for use in audits and quality assurance. 

How do I know when a mechanical seal should be replaced?

Typical signs of wear are increased leakage, changed noise level from the equipment or visible damage on inspection. We recommend regular inspection and replacement in accordance with operating conditions and cleaning frequency to avoid unplanned production stoppages.
