The causes that lead to a pump body failure can be diverse. Usually the most common are pressure spikes and cyclic loads, but by properly choosing the type of connections, performance and durability can be improved. Of the connections available, the so-called "cross" connection has the least resistance to cyclic loads. Other types are more robust. To learn more, read our article on the most common connections for hydraulic pumps. There is also a special type of pump rupture, called a "V-shaped" pump. This is an infrequent and avoidable occurrence because it is due to pressure on the discharge pipe. To learn more you can read our article on what are the causes of V-shaped body rupture and how to prevent it.
