Polypac Pump Rod Seal

Polypac Pump Rod Seal provides dependable sealing for hydraulic pumps, oil wells, and rod-driven equipment. Designed for low friction and long life, our rod seals reduce leakage, protect equipment, and lower maintenance costs. Built on decades of material expertise, these seals suit demanding conditions where reliability matters.

Why choose Polypac rod seal?

  • Durability: Engineered from PTFE blends and high-performance elastomers for wear resistance and stability.
  • Low friction: Optimized profiles and materials minimize stick-slip and improve pump efficiency.
  • Custom solutions: Tailored compounds (bronze-filled PTFE, carbon-filled PTFE, MoS2, NBR, FKM, EPDM, FFKM) for specific temperatures, pressures, and media.
  • Precision manufacturing: Produced in our 10,000+ m² facility with advanced testing equipment for consistent quality.

Materials and performance

Polypac leverages deep experience in PTFE and elastomers. From filled PTFE options to a wide range of O-ring materials, our pump rod seals resist chemical attack, handle high pressures, and perform across wide temperature ranges. This makes them ideal as hydraulic seals and oil seals in pumps, actuators, and subsea applications.

Applications

Common uses include hydraulic pump rod sealing, reciprocating pump rods, valve stems, and other dynamic sealing points. Polypac rod seals are suitable for oil & gas, industrial hydraulics, mobile machinery, and custom equipment where a reliable rod seal matters.

About Polypac

Since 2008, Polypac has specialized in sealed solutions, combining advanced production lines and collaborations with universities and research institutes. Our 8,000 m² factory space and modern test lab ensure each pump rod seal meets strict performance standards.

Q&A

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.
What is the difference between a static seal and a dynamic seal?
A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.
What does "AS568" mean?
AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.
Can I reuse a seal?
We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.
