The affinity laws for pumps express the relationship between the several variables involved in pump performance. The below calculation applies to centrifugal pumps and gives a good indication of the differences in pump capacity, pump head and absorbed pump power when changing the pump speed but with the impeller diameter remaining unchanged.
Three rotor screw pumps, also known as triple screw pumps, are a type of positive displacement pump commonly used in the petroleum industry for various applications. These pumps are designed to handle viscous fluids and provide a reliable and efficient pumping solution. In this article, we will explore the design, working principle, advantages, and applications of 3 rotor screw pumps.

Design of 3 Rotor Screw Pumps
Three rotor screw pumps utilize a unique design that sets them apart from other types of pumps. The pump consists of one power rotor and two drive rotors that spin inside a casing. The rotors have helical threads that intermesh with each other, creating sealed chambers between the rotors and the casing. As the rotors rotate, the fluid is trapped in these chambers and transported from the suction side to the discharge side of the pump.
The design of the 3 rotor screw pump allows for smooth and pulsation-free flow, making it ideal for applications where a constant and steady flow rate is required. The close tolerances between the rotors and the casing ensure efficient operation and minimal leakage of the pumped fluid.
Working Principle of 3 Rotor Screw Pumps
The working principle of 3 rotor screw pumps is based on the positive displacement concept. As the rotors rotate, they create expanding and contracting chambers that draw in and push out the fluid. The fluid is continuously trapped and transported through the pump, providing a consistent flow rate and pressure.
The intermeshing rotors also help to maintain a high level of efficiency, as there is minimal slippage of the fluid during the pumping process. This results in energy savings and reduced operating costs over the long term.
Advantages of 3 Rotor Screw Pumps
There are several advantages to using 3 rotor screw pumps in various industrial applications. Some of the key benefits include:
1. High Efficiency: The design of the 3 rotor screw pump ensures a high level of efficiency, resulting in lower energy consumption and operating costs.
2. Smooth Operation: These pumps provide a steady and pulsation-free flow, making them ideal for applications where a consistent flow rate is essential.
3. Versatility: 3 rotor screw pumps can handle a wide range of fluid viscosities and temperatures, making them suitable for diverse applications in the petroleum industry.
4. Low Maintenance: The simple design of these pumps minimizes the need for maintenance and reduces downtime, leading to increased productivity.
