No Power Steering driving, possible?

[dom14]

Hey Guys,

Is it safe & possible to drive with a disconnected power steering pump(GQ Patrol)?

Not that I'm going to do it, but just in case if the power steering pump poops itself in the
middle of nowhere, so I can get by to somewhere where I can source a replacement.

I'm sure the steering is even harder, but wondering whether the steering box can suffer as a result of driving without power steering.
Will it screw the steering box?
If I can drive for some distance without damaging the steering box, how far would that be?

Thanx
