What is churning in pumps?

When a pump is running with its discharge valve closed. The temperature inside pump rises continuously as the same liquid is continuously rotating inside pump. Due to rise in temperature of liquid, metal component's temperature also begin to rise. As the mass of impeller is much less than the pump casing. The expansion due to heat on impeller is higher than the casing. As there is very less clearance between pump casing and impeller. A time comes when impeller starts rubbing against the casing which further increases its temperature and the impeller seizes with casing. This is known as churning.
