The 7.3 HPOP is a seven piston axial pump. The swashplate angle determines the length of each pistons stroke and the greater the angle the longer the stroke and the larger the volume of oil that gets pumped, which is what causes the higher pressure of the oil. Also the larger the volume of oil that gets pumped the higher the sustainable pressure, ICP vs IPR duty cycle.
Some axial piston pump info. Axial Piston Pumps
For an inside view of the HPOP see this PDF.

Thanks for all the infor. It is very helpful.
If the 17 degree pump works ok on my E99 OSD I will order one. Also the hoses (in for a penny ...)
Is the gasket the same? I assume that the gasket etc comes with the pump.
Thanks again. We will get this PSD running right yet.

RIFF RAF shows the E99 as a 15 degree pump. Is that what I should order?
My truck is an E99 and probably has an 15 degree pump so I just wondered if getting a latter 17 degree pump would be an improvement.
Maybe Clay will give me some advice here.
I notice that the price is the same.

It will be a big improvement compared to the 15*
