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.

What are the components of a jet pump?
There are different kinds of jet pumps but some of the main components are motor, discharge, jet assembly, lift, suction, nozzle, control value, impeller, and venturi.
Do all shallow well jet pumps use a venturi tube?
All shallow well jet pumps use an ejector (or jet), which consists of a nozzle and venturi tube. Centrifugal pumps on the other hand are also shallow well pumps without a jet.
How do stand up jet skis drain?
They most commonly use a suction bailer system. This is a very simple and very effective bilge draining system. Essentially, a hose is inserted into the thrust portion of the pump in such a way that a vacuum is formed using a venturi effect. The other end of the hose goes to a box with holes in it at the bottom of the jet ski. Water in the jet ski is sucked into the bailer box and then into the pump and out the back.
How does a jet pump work in a water?
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.
How does a jet pump work in a water well?
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.
How do you shim a jet pump?
I have worked on jet pumps for years and never heard of shimming one. I can't even imagine where you would shim or why. Go to a good pump repair shop and ask.
What is a carburetor venturi?
A venturi is also called a "jet pump", an "injector", or an "eductor". As a fluid velocity is increased, its pressure decreases. A venturi is sued to increase fluid velocity, to obtain the lower pressures necessary to draw in some other fluid. Commonly used to drain water beds using flow from a sink, to add chemicals to a water stream, and to add gasoline to an air stream (in older engines).
What is the 3 main components of carburetor?
I'll give you 4. The Float System, the Fuel Jet, the Venturi Pipe and the throttle valve.
How do you convert a shallow jet well pump to a deep well pump?
Depending on your pump, you may not be able to convert it. There are three basic kinds of jet pumps for wells. Shallow, Deep and Convertible. In the typical configuration the shallow well pump is the easiest to identify. It should have a single opening (1 1/4" diameter) on the front face. All the pumps will have the discharge on the top of the pump (1 1/4" diameter). The dimensions in parentheses are from my old Montgomery wards 1.5 hp pump to give a reference. The Deep well and convertible pumps will have two openings on the face. Depending on the manufacturer and model they can be big on top or big on bottom. In the deep well installation, the eductor and venturi are usually located within 10' of the water surface during well drawdown. In the convertible installation the eductor and venturi are typically bolted directly to the face of the pump, covering the two holes and providing just the one suction line. Hopefully you have a deep well or convertible type with the eductor and venturi bolted to it. All you have to do is extend the two lines on the front of the pump to the eductor/venturi (within 10-feet of the water surface) and then continue one suction line don into the water and place a foot valve on the end. try going to the pump manufacturer's website and reviewing the installation manual, it should have some good pictures that will point you in the right direction.
When the second pump which is designed for spa whirlpool effect feature only is turned on the spa is draining water through the vent pipe How can you stop this?
If by vent pipe you mean the venturi pipe it sounds as if it is plumbed backwards, in a spa jet you have 2 feed conections, one for water (the bottom pipe) and another for air (top pipe) if plumbed incorrectly water will back up out the venturi line (vent pipe)
Where is the water pump located on a 455 Oldsmobile engine that's in my jet boat?
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.
