how does 3 stage pump work

A three-stage pump is a type of pump that uses three impellers to increase the pressure of a fluid. Each stage of the pump has an impeller that spins and moves the fluid from one stage to the next, increasing its pressure as it goes along. Here's how a three-stage pump typically works:

First Stage: Low-Pressure Inlet The low-pressure inlet stage is where the fluid enters the pump. In this stage, the impeller spins and moves the fluid into the next stage at a relatively low pressure.

Second Stage: Intermediate Pressure In the second stage, the fluid is moved through another impeller or rotor which further increases the pressure of the fluid. The pressure is now higher than in the first stage.

Third Stage: High-Pressure Outlet In the third and final stage, the fluid is moved through another impeller that further increases the pressure of the fluid to the desired high pressure. The high-pressure outlet stage is where the pressurized fluid is sent out to the system or application where it's needed.

Overall, the three-stage pump is able to achieve higher pressures than single-stage pumps by using multiple impellers to increase the pressure of the fluid in stages. This makes it ideal for applications that require high pressure, such as in oil and gas industry, water treatment plants, and high-pressure cleaning systems.
