Never start a ___ pump before making certain that the bearings are wet.

For a water-lubricated pump, the bearings rely on a thin film of water to separate the bearing surfaces and carry away heat. If you start the pump while the bearings are not wet, there’s no lubricating film yet, so metal-to-metal contact occurs, causing excessive friction and rapid overheating which can seize or damage the bearings. Ensuring the bearings are wetted by water before startup lets the film form and protects the bearings during initial operation.

The other types use different lubrication or cooling methods (air film, oil film, or cooling water), so the phrase about bearings being wet specifically targets the water-lubricated design.
