The inlet temperature of the mechanical seal pipeline is higher than the outlet temperature
Thread Content
During the performance testing of the centrifugal pump (4 stages, head 357, flow rate 345), it was found that the temperature at the inlet of the flushing line for the mechanical seal on the drive side (53B) was higher than the temperature at the outlet.
Is the inlet and outlet pipeline connected reversely?
The direction of rotation of the pumping ring is incorrect, or the pump is running in reverse
If the outlet temperature is higher than the inlet temperature, it means that this temperature is increased by the tank with model 53B, which implies that the tank has a heating function – and this goes against common sense. Could it be that hot water is flowing inside the tank’s jacket? Or it might really be installed backwards.
