Cargo Pump Coupling Guard Nuts secure the coupling guard in pump systems, ensuring safety and alignment. These nuts are typically made of durable materials to withstand harsh marine environments. Proper installation prevents accidental dislodging and protects the pump coupling from damage.

Size: Typically ranges from M6 to M20, depending on pump system requirements.

Grade: Commonly Grade 8.8 or higher for high tensile strength.

Viscosity: Not applicable (N/A) for solid components like nuts.

Buoyancy: N/A (solid metal components do not exhibit buoyancy).

Material: Usually made from carbon steel, stainless steel (AISI 304/316), or alloy steel for corrosion resistance and durability.

Thread Type: Metric coarse (standard) or fine threads, depending on application.

Surface Treatment: Zinc plating, galvanization, or Dacromet coating for corrosion protection.

Torque Specifications: Varies by size and grade (e.g., M12 Grade 8.8 ≈ 90 Nm).

Temperature Range: -50°C to +250°C (varies based on material and coating).

Standards Compliance: ISO 898-1, DIN 934, or equivalent industry standards.

The compliance of Cargo Pump Coupling Guard Nuts and Pump Systems with maritime standards depends on the specific standards they are designed to meet, such as those from organizations like ISO, ASTM, or classification societies like ABS, DNV, or Lloyd's Register. For exact details, refer to the product specifications or manufacturer documentation.
