The mechanical seal, also known as the seal kit, is responsible for maintaining the tight seal between the pump body and the motor of your pump. It is a wear part that is responsible for 90% of pump leaks. Typically, the mechanical seal needs to be replaced every 3-4 years. We offer the most common references for various pumps, but we can also source all the parts for massage and circulation pumps upon request for a personalized quote.Read more

Mechanical seals are essential elements for ensuring the tightness of your spa pump. They consist of a set of parts that compress against each other to prevent water leaks.
What is a mechanical seal?
Mechanical seals are mechanical sealing devices used to seal the ends of the pump shaft. They typically consist of two friction rings, known as faces, that are pressed against each other to form a tight barrier.
Different types of mechanical seals
There are several types of mechanical seals for spas, including single seals, double seals, and cartridge seals. Single seals are typically used for low-speed pumps, while double seals are used for high-speed pumps. Cartridge seals are easily replaceable and require little maintenance.
Mechanical seals are more reliable and durable than traditional O-rings, as they are designed to withstand high-temperature and high-pressure conditions. They are also easier to maintain and replace, which helps extend the lifespan of the pump.
How to choose the right mechanical seal?
The choice of the mechanical seal will depend on the type of pump you have. It is important to check the compatibility of the seal with your pump model before purchasing. You may also consider the lifespan of the seal, the material used for manufacturing, and the operating conditions.
