What are the specifications for transformer oil pumps?

Transformer oil pumps typically have specifications that include a flow rate ranging from 50 to 500 liters per minute, depending on the transformer size. They should operate at a pressure of 1 to 3 bar and be designed for temperatures between -10°C and 60°C. Additionally, the pumps must be compatible with mineral and synthetic transformer oils, feature corrosion-resistant materials, and include safety mechanisms to prevent leaks and overheating during operation.
