What is a Mechanical Seal?

Mechanical seals are the preferred method of sealing when it comes to sealing pumps that transport or use hazardous material. The mechanical seal secures the pump firmly and prevents almost all leakage.

 

Mechanical seals have a lengthy lifespan and are very durable. This has the benefit of the maintenance of the seal being low, and resources need not be wasted to constantly maintain the seal. Because the lifespan of the seal is long and the structure is sturdy, it further assists in maintaining the lifespan of the pump itself because the seal will not need to be repeatedly replaced, requiring the pump to be disassembled for this purpose, causing wear and tear.

 

Mechanical seals also have low energy consumption, thus allowing them to be in constant usage, and still maintain their lifespan.

 

What is a Slurry Pump Seal?

 

slurry seal is a form of mechanical seal. The slurry pump seal offered by First Seal is chemical, abrasion, and heat resistant. With its application in a variety of industries, it is predominantly seen in the petrochemical and mining industry, where hazardous chemicals are handled daily. The slurry seal is corrosion and heat resistant which makes it very suitable for this application. The nature of the slurry pump as a mechanical pump makes it the more durable and ultimately cost-effective option as it is hardy and capable of constant usage.

 

The design of the slurry seal is also that it can withstand and handle sudden failures and instant reverse pressures, adding to its durability.

 

The operating specifications of the slurry pump offered by First Seal include a pressure capacity of 0 – 2.5MPa, dealing with temperatures ranging from – 30 degrees Celsius to 220 degrees Celsius, with a speed threshold of up to 25m/s and are available in sizes ranging from 45mm – 200mm (metric) or 1.75” – 8” (Inch).
