Typically seals are cooled by water as it passes through the pump. If the pump is dry or has insufficient water for priming it could damage the mechanical seal. Oil-lubricated and occasionally grease-lubricated seals are available on some pumps that provide positive lubrication in the event the pump is run without water.

When plotting the pump "all pass" vibration (at the top of the motor) for the various operating speeds as shown in Figure 2 the vibration is not seen to peak at any distinct speeds (as would be expected with an unbalance or resonance issue) but instead there is much scatter. The only trend is that the vibration generally increases with speed.
