can this pump be run continuously for 6 or seven hours. psi is around 75 is that correct? suitable for engine requiring 2 gallon per min

In my application this pump is running continuously. However, I don't run at this pressure, my app is simply water circulation to cool a motor. And I'm not sure if this pump can generate this amount of pressure.

What is the smallest battry size to operate this pump?

It draws around 500mA. It just depends how long you need to run it. You should expect 1 hour with a 12V 500mA battery

1. Can it be used in either submersed or non-submersed conditions? 2. What is the maximum negative pressure head in non submersed condition ?

It will not work unless it is submerged and the second part of the question i have no idea.

Will this pump work with a 24v system?

This is a 12 volt pump. Running it at 24 volts would most likely damage the windings. Search for a 24V brushless pump like a DC40-2470 should get you close.
