  • Pump Cavitation: Causes, Effects, & Preventive Actions

    1. Pump Selection. The best way to prevent cavitation is to choose the correct pump for the application. Cavitation increases as the pump head (NPSH) falls or as capacity raises. so selecting the right pump to maintain a positive margin between NPSH available and NPSH required is the first move towards cavitation prevention.

  • Why Cavitation Occurs & Ways to Treat it | Pumps & Systems

    May 13, 2019 · The old joke about falling from a tall building is that "it isn't the fall that kills you, it is the sudden stop at the bottom." When it comes to cavitation, it is not the formation of the vapor bubbles that kills the pump, it is the subsequent collapse. There are plenty of articles on net positive suction head (NPSH) and cavitation that talk about the bubble formation and the

  • WATER COOLING SYSTEM - UNIRI

    The cooling water pump which may be engine driven or be a separate electrically driven pump pushes the water around the circuit. After passing through the engine, where it removes the heat from the cylinder liners, cylinder heads, exhaust valves and sometimes the turbochargers, it is cooled by seawater and then returns to the engine.

  • 8 Reasons Your Centrifugal Pump Has Low Flow

    Jun 09, 2016 · The problem can also be frustrating, but don't necessarily blame the pump (or resort to a black market pump!) just yet. Check these simple things first. 1. Reversed Impeller Rotation. This may seem like a no-brainer, but it really is a common problem. When wiring the pump's motor to power, it's important to test which way the motor is turning first.

  • What is Pump Priming and Why it is Required? | What is Piping

    Reason for Pump Priming. During starting a pump, if air, gas or vapor exists inside the pump casing, the pump will not be able to function properly. Pump will be subjected to the risk of damage. The air or gas present inside the pump will make it gas bound and the pump won't be pumping the desired liquid.

    Aug 05, 2014 · The pump gains additional inlet head or pressure if the liquid level is above the pump inlet or minus head if the liquid level is below the pump. The fluid weight creates the pressure. The pump loses inlet head or pressure from friction loss of the fluid moving through the suction pipe (small pipes or long pipes have a lot of friction).
