TECHNICAL DATA – NPSH
NPSH
Goulds Water Technology
The minimum operating values that can be reached
at the pump suction end are limited by the onset of
cavitation.
Cavitation is the formation of vapor-Ŷlled cavities within
liquids where the pressure is locally reduced to a critical value, or where the local pressure is equal to, or Nust
below the vapor pressure of the liquid.
The vapor-Ŷlled cavities ŷow with the current and when
they reach a higher pressure ares the vapor contained
in the cavities condenses. The cavities collide, generating pressure waves that are transmitted to the walls.
These, being subNected to stress cycles, gradually
become deformed and yield due to fatigue. This phenomenon, characterized by a metallic noise produced
by the hammering on the pipe walls, is called incipient
cavitation.
The damage caused by cavitation may be magniŶed by
electrochemical corrosion and a local rise in temperature due to the plastic deformation of the walls. The
materials that offer the highest resistance to heat and
corrosion are alloy steels, especially austenitic steel.
The conditions that trigger cavitation may be assessed
by calculating the total net suction head, referred to in
technical literature with the acronym NPSH (Net Positive Suction Head).
The NPSH represents the total energy (expressed in
feet) of the liquid measured at suction under conditions of incipient cavitation, excluding the vapor pressure (expressed in feet) that the liquid has at the pump
inlet.
To Ŷnd the static height (hz) at which to install the
machine under safe conditions, the following formula
must be veriŶed:
h
p + hzű (NPSHr + 2 ft) + hf + hpv
where:
h
p is the absolute pressure applied to the free liquid
surface in the suction tank, expressed in feet of
liquid hp is the quotient between the barometric
pressure and the speciŶc weight of the liquid.
h
z is the suction lift between the pump axis and the
free liquid surface in the suction tank, expressed in
feet hz is negative when the liquid level is lower
than the pump axis.
h
f is the ŷow resistance in the suction line and its ac-
cessories, such as: Ŷttings, foot valve, gate valve,
elbows, etc.
h
pv is the vapor pressure of the liquid at the operating
temperature, expressed in feet of the liquid. hpv is
the quotient between the Pv vapor pressure and
the liquidős speciŶc weight.
0.5 is the safety factor.
The maximum possible suction head for installation
depends on the value of the atmospheric pressure
(i.e. the elevation above sea level at which the pump is
installed) and the temperature of the liquid.
To help the user, with reference to water temperature
(40ºF) and to the elevation above sea level, the following tables show the drop in hydraulic pressure head in
relation to the elevation above sea level, and the suction loss in relation to temperature.
Water Temperature (ºF) 68 104 140 176 194 230 248Suction Loss (ft) -.7 2.3 6.6 16.4 24.3 50.5 70.5
To reduce it to a minimum, especially in cases of high
suction head (over 13 – 16 feet) or within the operating limits with high ŷow rates, we recommend using a
suction line having a larger diameter than that of the
pump’s suction port. It is always a good idea to position the pump as close as possible to the liquid to be
pumped.
