i believe the question should be stated as "How high can a pump pull liquid when mounted above the liquid source". an old pump adage is that a pump doesn't suck. sounds dumb, but it refers to the necessity of having a positive pressure at the suction of the pump greater than the required net positive pressure req'd by the pump. NPSHa must be greater than NPSHr. in any system open to atmosphere the surface of the fluid will have 14.7psi (at sea level) X 2.31 ft/psi, or roughly 34' of head, or NPSHa, available. the manufacturers performance curves will show the NPSHr of the pump at any given flow for a given impeller trim. by subtracting this NPSHr from the calculated surface pressure you can arrive at a general maximum lift that the pump can run at. there will also be line friction losses that will reduce this height, and typically we subtract another 2-3' for a fudge factor as you would not want to run on the ragged edge. so, a pump with an NPSHr of 8' would be able to lift cold water approx 22' before cavitating. getting it primed is another issue, and having said all this, there is a type of centrifugal that can successfully trick this seemingly rigid restriction on lift. the typical home commercial jet pump can lift from many times this limited depth by taking a portion of the high pressure discharge and sending it down a separate pipe and into the suction pipe. this effectively increases the suction pressure and allows this type of pump to lift from quite a depth. a really neat way around having to install a down-hole pump submersible. of course the type of pump, what you are pumping, temperature, vapor pressure, specific gravity, and viscosity will all affect the height that a pump can lift a fluid.
If the question is ' at what height we can place the suction side of pump from the water level from where it is pulled up', then if we are not considering the NPSH (which is not practical of course) , then i think that the maximum height of the suction side will be the height which will balance the pressure which is on the water level below from where it is pumped. If the pressure there is atmospheric pressure (at the water level below suction side)then maximum height of water rising is 10.3 m around(will vary according to the fluid being pumped). Above it water will not rise whatever vacuum you create though pump.(Its just like in barometer where Mercury doesn't rise above 760mm, although there is vacuum above it in the tube. This is because at base of inverted tube of barometer, pressure is balanced). In practical of course the height is much less of course otherwise cavitation will take place when pressure falls below Vapor pressure of the Liquid being pumped.

What was used to help pull water up from the aquifers found deep underground?
A pump, such as a submersible pump or a jet pump, is typically used to draw water up from aquifers found deep underground. These pumps create a vacuum that lifts the water to the surface for consumption or other uses.
How could you demonstrate boiling point?
A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.
Does water in a vacuum change temperature?
In a vacuum, water does not change temperature since temperature is a measure of average kinetic energy of molecules, which in turn depends on molecular collisions that require a medium. Without air or molecules to transfer heat, water cannot gain or lose temperature in a vacuum.
How long would it take to remove one cup of water from closed container using a two stage vacuum pump?
This is very difficult to answer as it would depend on:- 1. the capacity of the pump, 2. the temperature of the water, 3. the insulation on the container, 4. the heat input to the container and water. The problem is, that the water would cool down and freeze, which would reduce the evaporation to the point that there would be so little evaporation that it could take a from a couple of hours to a couple days.
What is the suction thing used to suck up liquids?
A device used to suck up liquids is called a vacuum pump or a suction pump. It creates a vacuum to draw in and remove fluids through a tube or nozzle.
What was used to help pull water up from the aquifers found deep underground?
A pump, such as a submersible pump or a jet pump, is typically used to draw water up from aquifers found deep underground. These pumps create a vacuum that lifts the water to the surface for consumption or other uses.
Why will a vacuum pump not operate for a well that is more than 10.3m deep?
Because the Earth's atmospheric pressure forces the water back down.
What is the working principle of deep well jet water pump?
A deep well jet water pump operates on the principle of creating a vacuum to lift water from deep underground. It consists of a jet assembly that uses a high-velocity jet of water to create a low-pressure area, allowing groundwater to be drawn into the pump. As water enters the jet assembly, it mixes with the high-velocity jet and is propelled upward through a discharge pipe. This system effectively utilizes the energy from the water flow to lift and deliver water to the surface.
Why does swimming pool pump out vacuumed water?
Because the pump is set to "vacuum to waste".
Why Stop boiling water Vacuum Chamber With the continuation of the vacuum pump work And vacuum pressure gauge -30 in hg Thank you?
You want to stop boiling water Vacuum Chamber because of the vessel seal. If the pump is boiling it will stop at the point of equilibrium.
As the pressure in a vessel containing water is reduced with a vacuum pump it begins to boil at some point but will it continue to boil if the vessel is sealed after it begins to boil?
If the vacuum pump is on, the water will continue to boil. If the vacuum pump is off as the vessel is sealed, the boiling will stop at a point of equilibrium.
What are the steps in converting deep well water pump to shallow well water pump?
A deep well submersible pump can be simply placed into a shallow well and it will work. These pumps actually pump water directly and do not rely on suction. Simply cut your tube to desired length and place the deep pump in the shallow well. -NOTE- this does NOT work the other way - a shallow or jet pump is just that and can never work in a deep well.
How do you install deep well water pump?
A deep well water pump is installed by mounting it in a weather resistant housing next to the well and running power to it. The hoses can then attached to either side of the pump and the pump tested for efficiency.
What type of pump do you need to drain 24' dia x 4' deep above ground pool?
You could use your pool pump. or get a submersible pump. it is also not difficult to siphon an above ground pool with a pool vacuum hose. all you need is somewhere to run the water to.
What is a jet well pump?
A jet well pump is a type of water pump commonly used for drawing water from deep wells. It operates by creating a vacuum that pulls water into the pump through a jet assembly, where high-velocity water creates a suction effect. These pumps are typically installed above ground and are suitable for applications where the water level is below the pump, making them effective for deeper wells. Jet well pumps are often used in residential, agricultural, and irrigation systems.
How do choose a vacuum pump Make water at Boil 1 degree C Thank you?
Choose a vacuum pump with a 29.75 hg that makes water boil 1 degree C. The typical boiling point of water is hundred degrees Celsius.
How deep does a pump go underground for water?
50 metes
