Why are you bleeding a puppy?
:?Your description of the noise being quieter at speed seems logical. When you drive faster, sound might be the same but drowned out by other road/wind noise. Also, since you are probably not driving through a chicane at faster speeds, the pump is not being taxed as it is at slow, parallel parking speeds.
I have not made the effort to search for an earlier post on this subject, but I recall a few. Forgive me if this is old or too obvious, but:
(1) have you examined, cleaned or replaced the filter that sits at the bottom of the pump reservoir (part no. 1 below)?
(2) Can it be that the screaming is really squealing from your belt drive? Too tight, or glazed, or worn, misaligned?
(3) Does one belt drive both the water pump AND your power steering pump? If the answer is no, don't read further. If the answer is yes: hint: there was a reason some models used a different belt routing from the crank. Water pumps and power steering pumps had different power demands. Belt tension that is adequate for driving a water pump may be inadequate to satisfy the steering pump. This can sometimes result in belt slipping or squealing.

Just when through this with my '73, power steering belt to water pump was very tight, but the belt aound the water pump/alternator and crank was loose (this is the belt that drives the water pump, which drives the power steering pump) Every time I turned the wheel it would squeal like a pig. I tightened up the alternator and it when away. Very poor design!

quickies
there are a couple of quick things to do with suspect belts, assuming they are worth messing with (i.e., not cracked, frayed, excessively worn or about to fail)
One. Make sure your belts are properly tightened. "Proper" to me means that you can twist the belt 90 degrees at mid-span between two pulleys.
Two. To test, dribble a little water on a suspect belt/pulley. If it stops squeaking/squealing, you've found the problem.
Three. Rub a little paraffin (candle wax) on a running belt to stop sqealing of a belt that's otherwise properly tight. DO NOT say I didn't warn you that this is a good way to twist off a finger.
Four. There are commercial "Belt Dressing" compounds sold in spray cans that you can use. A little can goes a long way.
