custmer said that caused by a pin hole , but as far as i know , if indeed as pin hole , the symptom is not like above..do you know why?


thank you so much !!!

if on suction side, you have less dripping when rpm increases (and air foam in the reservoir tank) drips a minute do not matter much.

if the 'pin hole' is on the suction side, then the symptoms you mention are correct.

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
