The SONTEK™ XA Mechanical seal is a high-performance Mechanical Seal typically used in industrial pumps. XA Mechanical Seal is a factory-assembled, pre-set sealing unit designed for centrifugal pumps and rotating equipment. XA Mechanical Seal is a single, unbalanced mechanical seal used in pumps and rotating equipment to prevent leakage of fluid along the shaft. It works by pressing a rotating seal face and a stationary seal face together, creating a tight sealing surface. Springs and secondary seals (such as O-rings) maintain contact between the faces and ensure proper sealing. XA mechanical seals are commonly used in centrifugal pumps, water systems, and light chemical applications because of their simple design, reliability, and easy maintenance. Main Components Rotary Face – Attached to the rotating shaft and rotates with it. Stationary Face (Seat) – Fixed in the seal housing and does not rotate. Secondary Seals – O-rings or gaskets that prevent leakage between components. Spring or Multiple Springs – Provide axial force to keep the seal faces in contact. Metal Parts – Hold and support the seal assembly.Working Principle
The rotary and stationary faces press against each other to form a sealing interface.
A very thin film of fluid forms between the faces to reduce friction and wear.
The spring force maintains constant contact between the sealing faces even when the shaft moves.
Features
Compact and simple design
Easy installation and maintenance
Good sealing efficiency
Suitable for water, oil, and light chemicals
Applications
Centrifugal pumps
Water treatment plants
Chemical processing industries
Food and pharmaceutical equipment
The SONTEK™ CS88B modified seal is a high-performance Mechanical Seal typically used in industrial pumps (such as those from Goulds, Flowserve, or Sulzer). While “CS88B” is a specific manufacturer designation (often associated with brands like Flowserve or AESSEAL equivalents), it belongs to the category of Teflon bellow.
Offered by Nexton Seals in Chawri Bazar, Delhi, this seal is widely preferred by pump dealers, repair workshops, OEM manufacturers, and industrial maintenance contractors.
The Bellows Unit (Top): The white, accordion-like section is made of PTFE (Teflon). This part provides the flexibility and spring tension needed to maintain the seal while resisting chemical attack.
The Seal Face (Dark Ring): The dark grey ring integrated into the bellows is the primary sealing face, likely made of Carbon or Silicon Carbide.
The Drive Collar (Center): This stainless steel cylinder contains set screws used to lock the seal onto the pump shaft.
The Stationary Seat (Bottom): This is the metal-clad ring with a white PTFE or Ceramic insert that remains fixed in the pump's stuffing box.
The Drive Collar (Middle Component)
The stainless steel cylinder in the center is the Drive Collar.
Function: It features set screws (the small holes you see) that tighten onto the pump shaft. This is what physically 'locks' the seal to the shaft so it rotates at the correct speed.

Single Spring Mechanical Seal – Detailed & Comprehensive Product Description
A Single Spring Mechanical Seal is a precision-engineered shaft sealing device designed to prevent leakage of liquids and gases in rotating equipment such as pumps, mixers, agitators, compressors, and reactors. Known for its simple yet highly effective design, this type of seal is one of the most widely used sealing solutions in industrial applications due to its durability, affordability, and ease of maintenance.
It is specially developed to provide consistent sealing performance under low to medium pressure and temperature conditions while ensuring minimal wear and long operational life.
🔧 Product Construction & Design
The Single Spring Mechanical Seal consists of carefully designed components that work together to create a reliable sealing system:
1️⃣ Rotary Seal Face
The rotating face is mounted on the shaft and rotates along with it. This component is commonly manufactured using high-quality materials such as:
Carbon Graphite
Silicon Carbide (SiC)
Tungsten Carbide (TC)
Ceramic
These materials are selected for their excellent wear resistance, low friction properties, and ability to withstand high temperatures and chemical exposure.
2️⃣ Stationary Seat (Mating Ring)
The stationary seat is fixed inside the pump housing and remains static. It is precision-lapped to create a smooth, flat surface that ensures proper contact with the rotating face. Materials typically include:
Ceramic
Silicon Carbide
Tungsten Carbide
The flatness of these faces is critical to maintaining leak-free performance.
3️⃣ Single Coil Spring
The core feature of this seal is its single helical spring. This spring applies uniform axial pressure, keeping the rotating and stationary faces in close contact. The spring automatically compensates for wear and shaft movement during operation.
Spring material:
Stainless Steel 304
Stainless Steel 316
Alloy Steel (for special applications)
4️⃣ Secondary Seals (Elastomers)
Elastomeric components prevent leakage between the shaft and seal parts. Depending on the application, different materials are used:
NBR (Nitrile Rubber)
Viton (FKM)
EPDM
PTFE
The elastomer selection depends on temperature, chemical compatibility, and operating environment.
5️⃣ Metal Hardware
All structural parts are made from corrosion-resistant stainless steel, ensuring strength and durability in harsh industrial conditions.
⚙️ Working Principle
The working principle of a Single Spring Mechanical Seal is based on maintaining continuous contact between two precisely machined seal faces.
When the pump shaft rotates:
The rotary face rotates with the shaft.
The stationary face remains fixed.
The spring pushes the rotating face against the stationary seat.
A microscopic fluid film forms between the faces, reducing friction and heat.
This film prevents leakage while lubricating the contact surfaces.
The result is efficient sealing with minimal product loss and reduced maintenance requirements.
📊 Technical Specifications (Standard Range)
Shaft Diameter: 10 mm to 150 mm (custom sizes available)
Operating Pressure: Up to 10–12 Bar
Temperature Range: -20°C to +200°C (depending on elastomer)
