Reliable Pump Rod Seal Replacement by Polypac

Polypac Pump Rod Seal Replacement is engineered to stop leaks, extend service life, and make maintenance fast and predictable. Built from advanced elastomers and filled PTFE variants, these seals suit pumps operating under pressure, varying temperatures, and chemical exposure.

Why Choose Polypac Rod Seals?

Long-lasting performance: High-quality materials like NBR, FKM, silicone, EPDM and PTFE blends resist wear and aging.
Precision fit: Custom sizes and profiles ensure a tight seal around pump rods to minimize leakage and rod wear.
Wide compatibility: Works with common hydraulic and reciprocating pumps and various rod finishes.
Easy installation: Simple designs reduce downtime and labor costs during replacement.

Designed for Tough Conditions

Whether you need heat resistance, chemical compatibility, or superior abrasion protection, Polypac offers material choices and filled PTFE options (bronze, carbon, graphite, MoS₂, glass) to match specific working environments. Each seal is produced in our modern facilities and tested to meet strict quality standards.

FAQ

How important is surface finish on the metal parts that contact the seal?

Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.

What is the difference between NBR and FKM materials?

NBR (Nitrile/Buna-N): A general-purpose, cost-effective material with excellent resistance to petroleum-based oils and fuels. It has a standard temperature range of -30°C to +100°C (-22°F to +212°F). FKM (Fluoroelastomer/Viton®): A premium material with excellent resistance to high temperatures (up to 200°C+), chemicals, and oils. It is used in more severe environments but is more expensive than NBR.

When should I use a spring-energized seal instead of a standard elastomeric seal?

Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.

What is the purpose of the metal spring in a rotary shaft seal?

The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.
