distinguish between centrifugal pump and piston pump|difference between diaphragm and centrifugal pump : store The pump can be driven by an electric motor or engine. Centrifugal pumps are usually used for liquids which are low in viscosity and low in solid concentration. However, there is a centrifugal slurry pump which can move liquids with a large amount of particles. The following are the essential components of a screw pump:. The screw rotor: This component is the most crucial element of a screw pump and is responsible for volume transfer and pressure generation. The stator: This stationary component forms a cavity with the screw rotor and is responsible for sealing the fluid and providing the necessary resistance to transfer .

When it comes to selecting the right pump for a specific application, understanding the differences between various pump types is crucial. Two common types of pumps used in the petroleum industry are centrifugal pumps and piston pumps. While both serve the purpose of moving fluids, they operate on different principles and are suitable for different scenarios. In this article, we will explore the distinctions between centrifugal pumps and piston pumps, highlighting their unique features, applications, and advantages.

Difference Between Centrifugal Pumps and Piston Pumps
**1. Operating Principle:**
- **Centrifugal Pump:** Centrifugal pumps work on the principle of converting rotational energy from an impeller into kinetic energy to move the fluid. The fluid enters the pump through the center of the impeller and is flung outward by centrifugal force, creating a low-pressure zone that draws more fluid into the pump.
- **Piston Pump:** Piston pumps, also known as reciprocating pumps, use one or more pistons to create a reciprocating motion that draws in and expels the fluid. The piston moves back and forth within a cylinder, creating a vacuum to draw in the fluid on the intake stroke and pushing it out on the discharge stroke.
**2. Flow Rate and Pressure:**
- **Centrifugal Pump:** Centrifugal pumps are suitable for applications that require high flow rates but relatively lower pressures. They are ideal for transferring large volumes of fluid quickly and efficiently.
- **Piston Pump:** Piston pumps are capable of generating high pressures, making them suitable for applications that require pumping fluids against high resistance or over long distances. They are often used in high-pressure systems where precise control over flow rate and pressure is essential.
**3. Efficiency and Maintenance:**
- **Centrifugal Pump:** Centrifugal pumps are known for their simplicity, high efficiency, and low maintenance requirements. They have fewer moving parts, reducing the risk of mechanical failures and minimizing maintenance costs.
- **Piston Pump:** Piston pumps are more complex and have a higher number of moving parts, which can lead to increased maintenance needs and higher chances of wear and tear. However, they offer precise control over flow rates and pressures, making them suitable for applications that require consistent performance.
**4. Applications:**
- **Centrifugal Pump:** Centrifugal pumps are commonly used in applications such as water circulation, wastewater treatment, HVAC systems, and general fluid transfer where high flow rates are required. They are also used in the petroleum industry for transferring crude oil, refined products, and various chemicals.
- Centrifugal pump: relies on the rotation of the impeller to generate centrifugal force to transport liquid. - Plunger pumps: pump liquids through the reciprocating motion of the plunger. - …
