Your pool pump is not pumping any water you have checked the impeller and motor and they are both fine you have tried repeatedly to prime but it just does not pump.I have also up a hose down the inlet?

Sounds like it is pulling air. the inlet pie must be leaking. You will have to excavate and look for damp or wet areas. Repair or replace the pipe.

Your JS 300 Jet Ski is not pumping water and over heating?
there are a few thing this could be i have had the exact same problem with my js 300 i have sloved mine with a new head gasket angetting the barrell skimmed but the other things are impeller to pump housing clearance a blocked inlet (take off pipe and blow through to check) or damaged impeller hope this helps
What feature prevents foreign objects from holding the bypass valve open in a dual impeller pump?
I belive the answer is: an inlet screen
What is the balance piston used for a centrifugal compressor?
Due to the pressure rise developed through the impeller, a pressure difference exists across the hubs and covers such that the impellers have a net thrust in the direction of the compressor inlet. The balance piston counteracts that by being located behind the last impeller. This is accomplished by subjecting the outboard side of the balance piston to a low pressure from the inlet side of the compressor thereby creating a pressure differential opposite to the direction of the impellers. This pressure is acheived by connecting the area behind the piston to the inlet using a line. The impeller thrust not balanced by the balace piston is absorbed by the thrust bearings. I hope this helps
How do you prime a shallow well?
To prime a shallow well, first turn off the valve to the water inlet and remove the plug from the pump impeller housing. Pour water through the funnel into both openings and reopen the inlet valve. Return plugs into original position.
What NPSH stands for and its meaning?
Net Positive Suction Head. It is the difference between hydraulic pressure and vapor pressure, usually of concern at the inlet of a pump. Without sufficienty high NPSH at a pump inlet, there will be cavitation in the pump. Within a centrifugal pump there can be pressures lower than at the inlet as the fluid is moved by the impeller. If any of those pressures is lower than the vapor pressure, vapor pockets- bubbles- form and you get cavitation. A more complete explanation: http://en.wikipedia.org/wiki/NPSH
Water is not pumping around your engine?
previously solved the same problem by squirting in water to inlet pipe and clearing scum and scale. No joy this time. neil
What is the balance drum used for a centrifugal compressor?
In a centrifugal compressor, the energy is transferred using a set of impeller blades and balancing drums. These balancing drums can be on the inlet or outlet side of the compressor and help to space out the energy in the compressor.
What is the significance of specific speed?
Specific speed (Ns) is a non-dimensional design index used to classify pump impellers as to their type and proportions. It is defined as the speed in revolutions per minite at which a geometrically similar impeller would operate if it were of such a size as to deliver one gallon per minute against one foot of head. The formula used to determine specific speed is Where N = Speed of Pump in RPM Q = Capacity in gpm at the best efficiency point H = Head per stage in feet at the best efficiency point The specific speed determines the general shape or class of the impeller. As the specific speed increases, the ratio of the impeller outlet diameter, D2, to the inlet or eye diameter, Di, decreases. This ratio becomes 1.0 for a true axial flow impeller. Low specific speed - Radial flow Impeller. Medium specific speed - Mixed flow Impeller. High specific speed - Axial Flow Impeller.
What are the names of the principle parts of a centrifugal pump?
The principle parts of a centrifugal pump are the pump casing, also called a volute, and the impeller. The other parts are the pump shaft, bearing(s), shaft seal, the wear rings, and the inlet and outlet. The impeller is mounted on the pump shaft. The pump shaft is coupled to an external power source like a motor. The motor turns the shaft, the shaft makes the impeller turn and the fluid being pumped is put in motion. The volute causes a change in pressure in the fluid. The shaft seal stops the fluid from leaking out of the casing (volute). The wear rings separate the high and low pressure areas inside the casing. The bearing(s) make the shaft turn easier. The inlet and outlet parts of the casing connect to the fluid piping system.
What is an example of an inlet?
I know a couple examples, all of which are in Long Island, NY: Shinnecock Inlet Rockaway Inlet East Rockaway Inlet Fire Island Inlet Moriches Inlet
What component regulates the pressure in a turbocharger?
Pressure in a turbocharger is regulated by various components such as exhaust gas pressure,condition of blower and impeller blades,condition of gas passage on suction and exhaust side,condition of air filters,closing and opening timings of exhaust and inlet valves.
How does concrete pump work?
Pumping of concrete is universally accepted as one of the main methods of concrete transportation and placing.In the past a simple two-stroke mechanical pump consisted o f a receiving hopper, an inlet and an outlet valve, a piston and a cylinder.The pumpwas powered by a diesel engine. The pumping action starts with the suction stroke drawing concrete into the cylinder as the pistonmoves backwards. During this operation the outlet value is closed. On the forward stroke, the inlet valve closes and the outlet valve opens to allow concrete to be pushed into the delivery pipe.
