Thermal Shock

Angus EwartTech TalkLeave a Comment

Our blog on “Total Discharge Recirculation” mentioned thermal shock as a destructive force that can damage or destroy pump components.  With how destructive this force can be, I thought it necessary to spend some time expanding upon this subject. What does thermal Shock mean in pumps? Wikipedia explains that thermal shock occurs when a thermal gradient causes different parts of an … Read More
