Application Note to the Field Why Use Relief valves ? Application Note Number: 0108-1 Date: August 7, 2001; Revised Aug. 2008. Positive displacement pumps, which are what gear pumps are, should not be deadheaded, as they will break immediately. The exception to this for gear pumps is when the viscosity is so low that the fluid slipping backwards through the pump is actually relieving it (giving the fluid somewhere to go). In this case, the pump will most likely still fail, but for different reasons and not immediately. What typically causes gear pumps to mechanically fail (excepting those due to heat or as directly related to the chemical) is torque, which is the result of the combination of differential pressure and viscosity. When the total torque exceeds the value that the weakest component can transmit, that part fails, which will eventually cause the pump to fail.
