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.
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.
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]
Your jet pump may not be building pressure due to a clogged intake, a leak in the system, a malfunctioning pressure switch, or a worn-out impeller. It is important to check these components to determine the cause of the issue.
In a jet pump, the venturi is situated within the pump's body, specifically in the converging section of the nozzle. As fluid enters the venturi, it experiences a reduction in cross-sectional area, which causes an increase in velocity and a corresponding decrease in pressure. This lower pressure creates a suction effect that draws in additional fluid, mixing it with the high-velocity jet produced by the pump. The combined flow is then expelled through the diverging section, converting the kinetic energy back into pressure.
The pressure switch in a well water supply system is typically located near the pressure tank. It is connected to the water line and is responsible for activating the pump when the pressure drops below a certain level and turning it off when the pressure reaches a specified point.

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.
