A mechanical seal is a precision sealing device used to prevent fluid leakage along the rotating shaft of pumps, mixers, agitators and other rotating equipment. It normally uses two closely controlled sealing faces, supported by secondary seals and other components.

We focus on application-based seal selection, dimensional compatibility, appropriate material selection and replacement solutions for industrial rotating equipment.

Mechanical seals are widely used in centrifugal pumps, chemical process pumps, food and dairy pumps, pharmaceutical equipment, textile and dyeing pumps, agitators and mixers, lobe pumps, screw pumps, water-treatment equipment, paper and pulp machinery, sugar plants, oil & gas equipment, and petrochemical equipment, where reliable shaft sealing is essential to prevent leakage and protect rotating equipment.

Yes. Custom seals can be developed according to equipment dimensions and operating conditions. We can work from an existing seal, drawing, shaft dimensions, equipment details or application requirements.

Yes. Ideal Seal Tech supplies OEM-equivalent/replacement mechanical seals designed to match the required dimensions, operating conditions and application.

Common equipment brands we work with include:

Flowserve, KSB, Sulzer, EBARA, Grundfos, Kirloskar, SPX FLOW, Wilo, Alfa Laval, Fristam, Johnson Pump, EagleBurgmann and John Crane.

OEM names are used only for identification/reference of equipment and replacement requirements. Ideal Seal Tech is an independent manufacturer/supplier unless specifically stated otherwise.

Common causes can include:

• Worn seal faces
• Incorrect installation
• Shaft runout
• Shaft or sleeve damage
• Excessive vibration
• Bearing problems
• Dry running
• Incorrect seal-face materials
• Excessive temperature
• Incorrect pressure conditions
• Chemical incompatibility
• Improper alignment
• Damaged O-rings or secondary seals

The actual cause should be determined before simply replacing the seal.

A new seal can fail prematurely if the underlying equipment or operating problem remains unresolved.

Check:

Seal → Shaft → Bearing → Alignment → Pressure → Temperature → Fluid → Pump operation

Replacing the seal without correcting the root cause can result in repeated failures.

Yes. Depending on condition and design, used mechanical seals may be suitable for inspection, refurbishment, repair or reconditioning.

Possible work may include:

• Seal-face inspection
• Lapping/polishing
• O-ring replacement
• Spring replacement
• Component replacement
• Sleeve inspection
• Dimensional inspection
• Reassembly
• Leakage testing where applicable

Not every used seal is economically or technically suitable for refurbishment.
