Bearings are a crucial component for centrifugal pumps. As to be expected, bearings cannot last forever in a centrifugal pump, and eventually, bearings will fail. “This is because pump bearings usually fail from causes other than fatigue”1. These causes of bearing failure vary greatly, however, the reasons include “excessive thrust, misalignment, inadequate lubrication, impact, static … Read more
Diaphragm pumps can be rather useful solutions to pump downtimes. For example, a diaphragm pump can continue pumping when the original centrifugal pump is down. Diaphragm pumps can be employed as a substitute in the short-term to replace a centrifugal pump in need of repairs. A diaphragm pump is “a type of reciprocating pump used … Read more
Pressure surging in pumping systems can be fatal and potentially destructive to pumps. Surging is “A sudden increase in the pressure of the liquid in a pipeline brought about by an abrupt change in flow velocity”1. The change in pressure can be a drastic increase or a decrease. A surge is also defined as “An … Read more
