Pumps are mechanical devices that play a vital role in various industrial processes. They are designed to move fluids, gases, or semi-solids from one location to another, ensuring the smooth operation of diverse industrial applications.
Pumps are essential components in various industries, including oil and gas, chemical, pharmaceutical, manufacturing, and water treatment. They are used to transport fluids, provide the necessary pressure for industrial processes, mix and blend fluids, control the flow of fluids,
In this article, we will discuss what is a pump? and type of pump in detail. First, let’s define what a pump is.
A pump is a mechanical device that uses mechanical energy to transfer fluids, gases, or semi solids from one place to another. It works by creating a pressure difference between the inlet and outlet, allowing the fluid to flow through the pump.
Pumps are classified into two main categories, determining their functionality and suitability for specific applications.
Positive Displacement Pumps (PD Pumps) move a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. They are driven by pistons, screws, gears, lobes, diaphragms, or vanes. The pumping action is cyclic and can be driven by reciprocating or rotary motion.
Dynamic Pumps, on the other hand, use kinetic energy to move fluids. They operate on the principle of imparting kinetic energy onto the liquid, involving three key steps: influx of liquid, acceleration of liquid, and deceleration or slowing down of liquid, resulting in pressure.
Rotary Pumps use rotating elements such as gears, impellers, or vanes to move fluids. They are commonly used for high-pressure applications and are preferred for pumping high-viscosity fluids.
Reciprocating Pumps use pistons, plunger, or diaphragms to move fluids. They are commonly used for metering or dispensing fluids and are preferred for applications where high accuracy is required.
Centrifugal Pumps use the centrifugal force generated by a spinning impeller to move fluids. They are commonly used for high-flow applications and are preferred for pumping low-viscosity fluids.
Piston pumps are a type of positive displacement pump that uses a piston to move and compress fluid in a chamber. This mechanism allows for precise control and the ability to generate high pressures, making piston pumps ideal for a variety of industrial applications.
Piston pumps move fluid by trapping a fixed amount and forcing it into the discharge pipe through a back-and-forth piston motion.
