High-Performance Mechanical Seal Manufacturer – VikTech Fittings

🔹 Product Overview

VikTech Fittings is a leading manufacturer and supplier of premium quality Mechanical Seals, designed to prevent leakage in pumps, compressors, and rotating equipment across industrial applications.

Our mechanical seals are manufactured in accordance with international standards such as API 682, ISO 3069, and ASTM standards, ensuring reliable performance under high pressure, high temperature, and chemically aggressive conditions.

Mechanical seals are essential for:

✔ Preventing fluid leakage in pumps and compressors
✔ Reducing downtime and maintenance costs
✔ Maintaining system efficiency and safety
✔ Handling aggressive chemicals and high-speed rotating shafts

🔷 What is a Mechanical Seal?

A mechanical seal is a sealing device that joins two parts (usually rotating and stationary) to prevent fluid leakage. Unlike packing, mechanical seals provide a frictionless seal with minimal wear and longer service life.

Mechanical seals are widely used in:

• Centrifugal and rotary pumps

• Agitators and mixers

• Compressors

• Reactors and process equipment

🔷 Types of Mechanical Seals

1️⃣ Single Mechanical Seal

• Basic design with one set of seal faces

• Suitable for moderate pressure and temperature

• Cost-effective and easy to maintain

Applications:

• Water and wastewater pumps

• HVAC systems

• Low to medium-pressure chemical systems

2️⃣ Double Mechanical Seal

• Two sets of seal faces separated by a barrier fluid

• Provides additional sealing under high pressure and toxic or hazardous fluids

• Can be unpressurized, pressurized, or tandem configuration

Applications:

• Petrochemical pumps

• High-pressure process pumps

• Hazardous chemical handling

3️⃣ Cartridge Mechanical Seal

• Pre-assembled unit for easy installation

• Reduces alignment errors

• Suitable for rotating equipment in critical operations

Applications:

• Industrial pumps

• Process industries

• Power generation

4️⃣ Metal Bellows Mechanical Seal

• Seal faces supported by metal bellows

• Compensates for axial movement
