What Is a Drum Pump?
Are you wondering what a drum pump, or barrel pump, is? If so, you have come to the right place. A drum pump is a portable pump that is designed to safely and efficiently transfer fluids from drums, barrels and storage tanks. Depending on the size and type of container, you can opt for many different drum pumps. They differ depending on pump configurations, designs, on-site power supply and the media being pumped.
How Does a Barrel Pump Work?
Most of the liquids used in manufacturing and processing plants are delivered in 100- or 200-litre barrels. In fact, these drums are too heavy to tip up so that the liquid could be emptied safely. On the other hand, may industrial establishments store feedstocks in Intermediate Bulk Containers (IBC) or large tanks. Barrel pumps, like those from Flux Pumps, are important to transfer media from these containers in an effective and safe manner.
A drum pump has a motor, a suction pump and an immersion tube. The motor is located on top of the immersion tube on the outside of the container. The immersion tube is as long as the depth of the container and is sealed to an opening on the top of the container. The pump section will be located on the lower end of the tube. It is driven from the other end of the tube with an extended shaft which is safeguarded by a sealed component. The pumped liquid will flow between the sleeve to the discharge port located at the motor end of the tube. There are different tube lengths that cater to different container depths. The product is constructed using different materials depending on the media that needs to be pumped.
Barrel pumps for medium and low viscosity fluids have an extended centrifugal pump with a double, single or multiple impellers. The rotation of this impeller will discharge the liquid up the tube and out of the port at the top of the immersion tube.
The Main Features of a Barrel Pump
A drum pump comes with several salient features that will be in contact with the fluid. The wetted parts will be resistant to corrosion and safe to use at the operative temperature in case the fluid is combustible or flammable. Pump tubes and the other parts are made from 316 stainless steel, polypropylene, CPVC, PVDF, and pure polypropylene.
The Pros and Cons of Drum Pumps
The main benefit of a barrel pump is that it helps eliminate the risk of manual handling of fluid containers. It prevents chemical splashes, leaks and toxic fumes that may result from manual handling of fluid drums or containers. Barrel pumps are portable and lightweight and could be easily transferred between containers.
There is a barrel pump designed for almost every application out there. For example, barrel pumps with double, single and multiple impellers are designed for fluids with low viscosity. Screw type pumps are ideal for liquids with medium viscosity as well as those containing small particulates. Progressive cavity designs are suitable for viscous fluids. They are capable of achieving gentle flows and low pulsation.
Barrel pumps are made for specific container sizes. For example, the immersion tube might not be long enough to reach the bottom of a specific container. But the parts are designed to be interchangeable and to allow you to re-purpose a drum pump quite easily.
