Fundamentals of Fluid Pumping - Process Phase
Fundamentals of Fluid Pumping - Process Phase

For a liquid at ,suction, of a pump if there is a head reduction equal to NPSH value, cavitation occurs causing the formation of bubbles. In other words, the static pressure of the ,suction, liquid shall be always greater than its vapor pressure. NPSH main usage is to prevent cavitation at the inlet of the pump.

Colin Jones has seen many mistakes in the installation of pool ,pumps,, particularly in the length and size of the ,suction, pipe. “Keep the ,suction, line to no more than 10 metres in length. A pump with a ,suction, line of 2 to 3 metres (compared to a longer ,suction, line) will outperform a similar pump in flow, power consumption and noise.

Such ,pumps, are lowered into the well to the water level, pump it up and raise it up. In the case of a well, the pump is also equipped at a depth sufficient for injection. The ,suction, height of the ,pumps, is most often 8 m, and they can push water to a rather high height. For example, in a well 90 m deep, the pump is installed at a depth of 60 m.
