28 Psi, with a 30 to 50 psi switch, ... on any system, whether it be jet or submersible the tank , empty witwithout water in it, should be 2psi below the switch "on" point
What size nozzles? What is the GPM rating What is the available pressure What lenght of the hose (fricton losses)
The most basic jet pump has a round pump chamber containing an impeller. The outlet to the well is large and the outlet to pressure tank is small. When the pump is primed and switched on it will suck water in and expel it at a higher rate. They are very susceptible to air leaks -every connection MUST be airtight.
Jet fuel is injected into high pressure air in jet engines.
Yes you can if the water level from the inlet of the pump is less than 25 feet. That's the limit of a shallow well jet pump. It can lift water physically 25 feet vertically, no more. If the well casing diameter is three inch or larger you could also install a submersible pump.[url="http://www.pumpsandtanks.com/Pumps/jet_pumps.htm"]Jet Pumps[/url]
There are many variables here, so I will answer as best as I can. The pump cost itself depends on whether it's a Shallow Well jet pump, a Deep jet pump or a Deep Well submersible. A shallow jet pump can be found as low as 350 for a reasonable 1/2 hp model that will suck from about 24 feet max. -A deep well jet can suck from 80 feet, and these are seldom less than 550 or so to buy.An average 3/4 hp submersible (which I believe to better in every case, even in shallow wells) will cost you around 750-800 for a good new one. These will pump (rather than suck) from anywhere down to 5-600 feet. I always prefer to use these type of pumps as they are far more reliable, easy to fit and long lasting. -More money to begin with, but a much better deal ! -Other necessities are the drop tube and wire, For tubing I always use 1" polypropylene thick wall tube - about 70 cents per foot. For a submersible also add 14/4 wire which runs about a dollar per foot (all the way down to the pump.) -Wire for a jet pump is negligible as the pump is on the surface.It takes about 5-6 hours labour to fit a deep well sub pump and about 4-5 to fit a jet pump. I don't know where you are, so can't price labour. Here in western Canada it runs 85-105 per hour.Some other tips- Definitely NOT a good idea to use old tubing for the pumpdrop. - If it's a deep well Submersible always change the control box.- If its a jet pump of any type, heat all tubing before connecting and doing up clamps. Most problems with jetpumps start with small air leaks at badly connected tubing. - Alwaysmount a shut off ball valve between jet pump and pressure tank. -You'll see why when you prime it !- Before starting either pump first time, make sure your pressure tank has an adequate air charge !
The pressure switch is usually on the pump if it's a jet pump, or at the base of the pressure tank if a submersible pump.

bad check valve or a leak.
Did you "RE-PRIME" the pump after you changed the pressure control switch? A likely reason you are not getting water would be that the pump "PRIME" was lost when you changed the pressure control switch. Pump seals can be burned up quickly if you run a jet well pump with no prime (lost prime) and will cause them to leak around pump shaft.
Depends what kind of pump. -If a submersible pump, the AMP test is good. If amps are within 'service factor' and pressure is still low, you have a bad 'wet end' or a leak somewhere. - If a jet pump, it may be cavitating, have a blocked nozzle, or have a warped impeller.

There are two types of jet pumps. Deep well jet and shallow well jet. The deep well has it's jet (ejector) in the well. The jets come in two different configurations. Two pipe and single pipe. The two pipe uses two pipes lowered into the well to the existing water level with the jet on the end. The single pipe jet is hung in the well with only one pipe. The jet has two leathers to seal it to the casing making the casing the second pipe. The shallow well jet pump has it's jet on or in the pump. These pumps can only lift water 25 feet. Once primed, the jet pump will force water down the pressure pipe into the jet, where it will be sent through a nozzle (of differing sizes depending on pump and water level) and into a Venturi tube (also differing in sizes) which creates a vacuum that will send more water up to be captured in the storage tank.
the water comes from the jet pump that propels your jet boat forward. there is plate over the hole where the car type water pump would be. typically.
The pressure ratio in jet engines is the ratio of pressure between the entrance of the compressor and the exit of the compressor.
Pressure of WHAT .
A person urinates more when lying down with their legs raised because there is a lot of pressure in the urinal bladder. This makes a person urinate longer with a stronger jet because less reserves are left in the bladder.
