Jet pumps are an essential component of watercraft propulsion systems. They work by drawing in water through an intake, compressing it, and then expelling it through a nozzle to create thrust. There are several different styles of jet pumps, each with its own unique characteristics and advantages. In this blog post, we'll explore some of the most common styles of jet pumps used in watercraft.
​

1. Axial-Flow Jet Pump The axial-flow jet pump is the most common style of jet pump used in personal watercraft. This style of jet pump has an impeller that draws water in from the intake and then expels it through a straight nozzle. Axial-flow jet pumps are efficient, compact, and produce high thrust. They are also relatively easy to maintain and repair.
2. Mixed-Flow Jet Pump Mixed-flow jet pumps are similar to axial-flow jet pumps, but they have a curved nozzle instead of a straight one. This design allows for a smoother flow of water through the pump, which can result in improved efficiency and performance. Mixed-flow jet pumps are commonly used in larger watercraft such as jet boats.
3. Radial-Flow Jet Pump Radial-flow jet pumps have a unique design that utilizes a curved impeller and diffuser to create thrust. Water is drawn in through the intake and then directed to the impeller, which accelerates the water and expels it through a curved nozzle. Radial-flow jet pumps are known for their high efficiency and ability to handle high flow rates.
4. Venturi Jet Pump The venturi jet pump is a specialized style of jet pump that uses a venturi tube to create suction and draw in water. Water flows through a narrow section of the tube, which creates a low-pressure area that draws in additional water. Venturi jet pumps are commonly used in applications where high suction is required, such as in firefighting or dredging operations.
5. Ejector Jet Pump Ejector jet pumps utilize a high-velocity stream of water to create suction and draw in additional water. The high-velocity stream is generated by a separate pump or by the watercraft's propulsion system. Ejector jet pumps are commonly used in industrial applications such as wastewater treatment plants.

In conclusion, jet pumps come in various styles, each with its unique features and applications. Axial-flow jet pumps are the most common in personal watercraft, mixed-flow jet pumps are popular in larger watercraft such as jet boats, radial-flow jet pumps are known for their high efficiency and ability to handle high flow rates, venturi jet pumps are specialized for high suction applications, and ejector jet pumps are commonly used in industrial applications.

​How to Build a Jet Ski Impeller
​
If you're a fan of personal watercraft and want to improve their performance, building your own jet ski impeller could be a great option. Impellers are a key component in the propulsion system of jet skis and are responsible for generating thrust by drawing water into the craft's impeller housing and then expelling it through a nozzle at high speeds.

Here's a step-by-step guide on how to build a jet ski impeller:

Step 1: Design the Impeller

The first step in building a jet ski impeller is to design it. You can use 3D modeling software to create a detailed design, or you can draw the impeller by hand on paper. The design should include the shape and size of the blades, the diameter of the impeller, and the pitch angle of the blades.

Step 2: Build the Casting Jig

Once you have the design, the next step is to build a casting jig. The casting jig is used to make the mold for the impeller. You can build a casting jig out of wood or metal, depending on your preference. The jig should be the exact shape of the impeller and should have a hollow core to allow the molten metal to fill the mold.

Step 3: Cast the Impeller

After the casting jig is completed, you can cast the impeller. You'll need to melt the metal, typically aluminum, in a furnace until it becomes liquid. Then, pour the molten metal into the casting jig and allow it to cool and harden. Once the metal has hardened, you can remove the impeller from the jig.

Step 4: Clean and Finish the Impeller

After the impeller has been removed from the casting jig, it will have rough edges and may require additional finishing. You can use a grinding wheel or sandpaper to smooth out the edges and give the impeller the desired finish.

Or

MACHINE Impeller

Machining an impeller out of aluminum or steel is another option for building a custom impeller. Machining an impeller can offer more precise control over the design and manufacturing process, allowing for greater customization and tighter tolerances. However, machining an impeller requires specialized equipment and expertise, and may be more expensive than casting an impeller.

One advantage of machining an impeller is that it allows for the use of stronger materials than those typically used in cast aluminum impellers, such as stainless steel or titanium. These materials can offer improved durability and resistance to wear, making them ideal for high-performance jet ski applications.

However, machining an impeller requires a solid block of material, which can be expensive and wasteful compared to the casting process. Machining also requires specialized equipment, such as a CNC machine or lathe, and may require more time and expertise to produce a finished product.


Step 5: Install the Impeller

Once the impeller has been cleaned and finished, it's ready to be installed in the jet ski. The impeller should be placed in the impeller housing and secured in place with bolts or screws.

In conclusion, building your own jet ski impeller can be a rewarding and cost-effective way to improve your craft's performance. By following these steps, you can create an impeller that's customized to your needs and preferences. Remember, it's important to take your time with each step to ensure the impeller is built correctly and works safely.

A custom impeller typically starts at $10k to build from scratch depending on size.

​Although they may sound alike, impellers and propellers have distinct purposes and functions. Despite being employed to propel a boat, they operate in fundamentally different ways. A propeller functions as a fan, pushing against fluid to generate forward movement by converting rotational force into linear motion. On the other hand, an impeller serves as a rotor that is typically integrated into a pump and generates a suction force, drawing fluid into a vehicle or engine. To gain a better understanding of these elements and their functions, let's delve deeper into each of them.

In simple terms, an impeller is a rotor component that generates a suction force within a pump system. In the case of a boat, the impeller is composed of a series of flexible rubber vanes attached to a central hub, which rotates around an axis inside a stainless-steel liner housed within the pump. This mechanism pumps cold water into the boat's engine to cool it down while under load, and is also used to bring water from outside the boat into the plumbing system.

The impeller features an inlet that allows water to flow into the boat, and the rubber vanes propel the fluid through the inlet. As the rotating component of a centrifugal pump, the impeller drives fluid away from the center of rotation, transferring energy from the pump to the water and creating velocity that propels the water outward from the pressurized pump. The impeller can be likened to an early and rudimentary version of the Archimedes screw.

Impellers can be classified into three different categories based on solidity: high, medium, and low. High solidity impellers feature large, square-shaped blades that are primarily used for gas dispersion and blending of high or medium viscosity fluids. The specific design and size of these blades prevent gas from bypassing them, which could easily occur if the blades were narrower.
​
In contrast, low solidity impellers have much thinner blades than high solidity ones and are typically employed for blending low viscosity fluids and solid suspension. Medium solidity impellers fall somewhere between high and low solidity types.

​A propeller can be thought of as a type of fan that generates thrust by pushing fluid away from it, converting rotational motion into linear motion (extrinsic). In the context of a boat, the propeller works by creating thrust and generating power to propel the boat forward. Propellers typically have three or four blades that rotate around an axis, driving the boat through the water. As the blades rotate, the water pressure behind each blade increases, propelling the boat forward.
​
The angle at which the blades protrude from the hub allows water to flow from the front of the propeller to the rear without pushing water to the sides. Generally, increasing the number of blades on a propeller can enhance the power generated by the vehicle and reduce drag. The thrust generated by propellers can be explained by either Bernoulli's theorem or Newton's laws of motion.

Cavitation is a common problem in centrifugal pumps that can cause damage to the pump and decrease its efficiency. Cavitation occurs when the pressure in a fluid drops below the vapor pressure of the liquid, causing bubbles to form and then collapse. This can lead to erosion, noise, vibration, and reduced pump performance. In this post, we'll discuss the common causes of cavitation in centrifugal pumps and how to prevent it.

Damaged Impeller A damaged impeller is one of the most common causes of cavitation. The impeller is the rotating part of the pump that moves the fluid. When the impeller is damaged, it can create turbulence and low-pressure areas that lead to cavitation. To prevent this, it is important to regularly inspect and maintain the impeller.

Bad Wear Ring The wear ring is a stationary part of the pump that surrounds the impeller. It helps to maintain the proper clearance between the impeller and the pump housing. A bad wear ring can cause cavitation by allowing too much fluid to leak back into the inlet side of the impeller, creating a low-pressure area and leading to cavitation. To prevent this, the wear ring should be regularly inspected and replaced as needed.

Bad Driveline Seal The driveline seal is the seal between the pump and the motor. A bad driveline seal can allow air to enter the pump, which can cause cavitation. To prevent this, the driveline seal should be regularly inspected and replaced as needed.

Bad Pump Seal The pump seal is the seal that prevents the fluid from leaking out of the pump. A leaking pump seal can allow air to enter the pump, leading to cavitation. To prevent this, the pump seal should be regularly inspected and replaced as needed.

In conclusion, cavitation can be caused by a damaged impeller, bad wear ring, bad driveline seal, and pump seal. To prevent cavitation, it is important to regularly inspect and maintain these components. By doing so, you can improve the efficiency of your pump and extend its lifespan.

To make a propeller testing session worthwhile, there are several important factors that must be considered. According to Dirk Bjornstad, the brand manager at Mercury Propellers, many people underestimate the number of variables and the level of stringency required when testing. Simply adjusting pitch alone won't suffice; blade count, cup, rake angle, and blade area are equally crucial. Additionally, a stepped-bottom design will necessitate different prop requirements than a standard one. By carefully examining these factors, you can make an informed decision.

When consulting with a customer, Brett Anderson, the president of BBlades Professional Propellers, emphasizes understanding their main goals and what they hope to achieve. Common objectives include getting on plane quickly, having great mid-range, and outpacing a friend's boat. However, even the most knowledgeable prop specialist cannot assist without accurate knowledge of your boat, such as the manufacturer's recommended maximum rpm for the engine.

As fuel prices rise in the spring, Bjornstad reported that he received calls from people seeking to save money. The most prevalent misconception was that increasing pitch could result in fuel savings. However, this has the opposite effect as it puts more strain on the motor, leading to increased fuel consumption. To save money, aim for the lower end of your motor's recommended rpm range. This will reduce gas consumption during high-speed runs as the engine will be turning at a lower rpm.
