A volumetric pump is a mechanical device widely used in many industrial settings. Find out how it works, the existing types, and all its advantages, and check out Fluid-o-Tech's offering!
A volumetric pump is a mechanical device used to transfer a fluid from point A to point B by the movement of a pumping chamber.
This pump ensures constant and smooth flow; in fact, it is designed to move a fixed volume of fluid per pumping cycle. Unlike other types of pumps, volumetric pumps offer precise control over the amount of fluid transferred and are able to adapt to a wide range of operating conditions.
Volumetric pumps can handle viscous, corrosive, or solids-containing fluids, making them a reliable and durable choice for many applications.
Precisely because of their great versatility, they are used in a variety of industries, such as:
• chemical engineering
• food and beverage industry,
• agricultural sector
As previously mentioned, a volumetric pump operates by a basic principle: the transfer of a fixed volume of fluid for each pumping cycle. There are different types of volumetric pumps, but they all operate by following the same basic mechanism.
Here's how it works:
• First, the fluid to be pumped is drawn into the pumping chamber through an inlet opening
• Next, the chamber is reduced in volume, increasing the pressure inside and pushing the fluid toward the outlet opening
This cycle of suction and discharge repeats continuously, allowing fluid transfer in a continuous and controlled way.
Each cycle of operation is completed when full rotation (360°) of the drive shaft is achieved.
As mentioned above, there are several types of volumetric pumps, which are generally classified into:
• Rotary pumps - are driven by rotary elements such as gears, lobes, vanes or similar elements. These components are driven by a rotating shaft, generating the motion necessary to pump fluid. Rotary pumps are used to convey dense and/or highly viscous fluids, and the flow rate is independent of the pressure difference. The rotor is driven by an electric motor
• Reciprocating pumps - use a reciprocating-motion organ to apply pressure energy directly to the liquid. They can be divided into single-acting pumps (if the piston works only in one direction), or double-acting pumps, if the piston works in both one direction and the other.
The main advantages of a volumetric pump include:
• Precise flow control for even fluid distribution
• Adaptability to different operating conditions, a factor that makes them particularly versatile and suitable for use in various industries
• Wear resistance that results in increased durability and reliability over time, reducing maintenance and replacement costs
• Ability to handle sensitive fluids that could be damaged by more aggressive pumping solutions
