According to BA (Page 64); the 964 pump delivers 65 liters of oil per minute and the scavenge pump has 1.84 times the capacity of the pressure pump.

At what engine RPM are these rated specs ?

65 liters (volume) per minute for the pressure pump.
119.6 for the scavenge pump.

65 liters is roughly 68 quarts that the pump will be able to potentially pump at the relief valve pressure per minute.
The scavenge pump has the capacity to move 125 quarts , 31.25 gallons which is a gallon per second, and there is no relief pressure valve.

I have a 964 pump in my motor, and want to make sure the oil thermostat and the oil cooler / cooler lines have enough volume capacity to handle the potential volume output.
I know some of the scavenge volume will be air which can be compressed.

I want to avoid trying to send more oil from the scavenge side of the pump than the lines, thermostat, cooler and static losses can handle.

Any help and or, real applications that have worked is appreciated.
