What types of media can this pump handle?

It is suitable for water, oil, and normal acid/alkaline liquids. Pre-testing is required for special liquids.

What is the difference between 2-phase and 3-phase models?

2-phase (T series) uses Hall sensors with the circuit inside the pump. 3-phase (S/A series) is sensor-less with the circuit outside, allowing higher temperature resistance.
