Fuel oil transfer pump seals are critical components designed to prevent leaks and ensure efficient fuel transfer within fuel systems. These seals must withstand high pressures, temperatures, and exposure to various fuel types. Proper maintenance and material selection are essential for durability and system reliability.

Size: Typically ranges from 1/2" to 4" in diameter, depending on application requirements.

Grade: Compatible with ASTM D396 or ISO 8217 standards for fuel oil.

Viscosity: Suitable for fuels with viscosities ranging from 2 cSt to 700 cSt.

Buoyancy: Not applicable; seals are designed for fluid containment, not buoyancy.

Material: Common materials include Nitrile (NBR), Viton (FKM), PTFE, or Aflas for chemical resistance.

Pressure Rating: Typically 100-300 psi, depending on seal design and material.

Temperature Range: -20°C to 150°C (-4°F to 302°F), varying by material.

Seal Type: Mechanical seals, lip seals, or O-rings, depending on pump design.

Compatibility: Resistant to diesel, heavy fuel oil (HFO), and marine gas oil (MGO).

Standards: Meets API 682, ISO 21049, or other industry-specific requirements.
