dry.The pump has a cooling fan.Air enters the pump at the bottom and exits
through the top rear. It is important that the air flow not be obstructed.
During normal operation, the pump may get warm from the precision step-
per motor.This condition is normal.
Output Pressure

an increase in fluid back pressure will cause the flow to decrease slightly.
