Garlock PS SEALS are the agitators and mixers designed to join liquids or prepare solutions and suspensions.
It is very common to find them in a multitude of industries, but particularly in the food and pharmaceutical industries due to the fact that mixing processes are especially necessary.
In our blog entry, we will tell you why the PS SEALS high performance seals from Garlock are a perfect solution.
In this way, we hope to help all those manufacturers and operators of these types of machinery who face constant challenges in these sensitive sectors.

A suitable sealing solution must meet certain standards to ensure process hygiene. In addition, the part must have a suitable design to ensure cleanliness and exclude microbial (no dead zones) or particulate contamination.
The cleaning processes are carried out by CIP and/or SIP (In this blog entry we explain it in detail), which involve temperatures of 90º C to 140º C and chemical disinfection agents.
It is precisely for this reason that sealing solutions must be particularly resistant to temperature and chemical media.
Abrasive media also pose a special challenge in environments where mixers and agitators are present. These abrasive media can be crystalline structures such as sugar, powders, grains and many other organic and inorganic raw materials.
Mixing dry ingredients requires that the sealing materials and all compounds as they are mixed at high peripheral speeds have excellent wear resistance.
In the food, pharmaceutical and cosmetics industries, materials are often mixed under vacuum and high pressure.
The process steps take place one after the other or in parallel in a closed system. Therefore, the materials of the sealing solutions must be able to withstand high pressures and extreme vacuum processes in addition to all other requirements.
Choosing a suitable sealing solution is vital to avoid cross-contamination of different formulations that could cause entire batches to become unusable.
Contamination can get trapped in the seal and subsequently leach into the batch which could have negative consequences. Apart from contamination, wear of a sealing solution can cause leakage and consequently shut down the production line.
It must also be ensured that the sealing solution can withstand dry operating conditions.
Food and drug safety is a key factor. Health authorities and consumers demand that products in these sectors offer high levels of quality and safety throughout the production chain, since the end users are people.
The sealing gasket must comply with all essential certifications for the food and pharmaceutical industry, so that machine manufacturers and operators of mixing plants and agitators can be sure that their equipment complies with all regulations and requirements.
It is worth mentioning the following certificationsCE 1935/2004, FDA and USP Class VI.
The line of PS SEALS products from the renowned multinational fluid sealing manufacturer Garlock, is one of the perfect solutions to meet the challenges of the mixer and agitator industries mentioned above.
PS SEALS is synonymous with reliable sealing of rotating shafts at high circumferential speeds, high pressures and extreme temperatures.
Here are its benefits:
In addition, the PS-SEAL® comes in countless configurations and lip and gasket materials to meet any individual requirement.
