This standard specifies the type, basic parameters, technical requirements, test methods, inspection rules and marking, packaging, transportation and storage of oil transmission gear pumps (including external gear pumps and internal gear pumps). This standard is suitable for transportation that does not contain solid particles and fibers, the temperature is not higher than 150°C, and the viscosity range is: 5×10m/s~1.5×10m/s (external gear pump), 1×10m/s~3×10m/ s (internal gear pump), a pump with lubricating oil and liquids with properties similar to oil.
