3 rotor screw pump|circur pumps 3 screw : distributors Three rotor designs utilize one power rotor and two drive rotors which spin inside the casing creating a rolling motion. This motion between the rotors and the fluid being pumped creates a barrier separating the rotors from contact and friction. Hi All, I want to tabulate the pump efficiency vs. flow rate for a pump that I am doing power requirement calculation. As you can see in the attached pump curve, the efficiency curves are the looping curve extending over a range of flow rates. I want to tabulate the pump efficiency vs. flow.

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.
