Single screw pumps Also known as Single Helical Rotor Pump, Progressive Cavity Pump,Eccentric Screw Pump. Working Principle The pump design consists of a single helical external threaded metallic rotor that rotates eccentrically inside a double helical internal threaded elastomeric stator of the same minor diameter and twice the pitch length .

The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was .
Centrifugal pumps, unlike rotary pumps such as gear pumps and screw pumps, provide variable flow rates over a range of pressures. These pumps are commonly used with high viscosity liquids, offering flexibility in flow rates and efficient operation. In this article, we will delve into the analysis of centrifugal pumps, exploring their design, performance, and applications.
Centrifugal pumps on the other hand, provide variable flow. rates over a range of pressures. Rotary pumps include gear pumps and screw pumps. used with high viscosity liquids. Examples of these pumps are shown in Figure 2. pumps due to their flexibility in flow rates and
Design and Operation
Centrifugal pumps operate by converting rotational energy from a motor into kinetic energy in the fluid being pumped. This kinetic energy is then converted into pressure energy as the fluid exits the pump through the discharge outlet. The key components of a centrifugal pump include the impeller, casing, and shaft. The impeller is responsible for imparting velocity to the fluid, while the casing directs the flow and increases the pressure of the fluid.
Performance Analysis
The performance of a centrifugal pump is typically evaluated based on factors such as flow rate, head, efficiency, and power consumption. The pump curve, which plots the relationship between flow rate and head, is a critical tool for analyzing the performance of a centrifugal pump. By examining the pump curve, engineers can determine the operating point of the pump and optimize its performance for a given application.
Applications
Centrifugal pumps find wide-ranging applications in various industries, including oil and gas, water treatment, chemical processing, and HVAC systems. These pumps are suitable for transferring liquids with low viscosity and are ideal for applications requiring high flow rates and moderate to high pressures. Centrifugal pumps are also commonly used in irrigation systems, fire protection systems, and wastewater treatment plants.
