Tips For Choosing a Drum Pump

What’s a Drum Pump?

This is simply a movable diaphragm pump that’s used to empty IBCs, carboys, drums, barrels, and tanks. Since most liquids used in the processing and manufacturing industries tend to be delivered in 100 to 200-litre drums, they are too heavy to tip and empty the contents inside.

Why Should You Use a Drum Pump?

These pumps are meant to give you a safe and easy way to transfer practically any liquid from barrels and drums. There are numerous varying models and tube lengths, and thus being able to meet your needs. So, how do you pick the right one? Well, you will find the following tips to be of great assistance in the selection process:

Stage 1: Determine Your Requirements

The first and most important thing to determine is how the drum pump will be used before you can settle on a particular pump series, motor type, tube construction as well as the accessories:

The Needed Head and Flow

Many applications of drum pumps are a simple transfer, but there are those that call for higher flow rates or higher head capability like transferring liquids to a second floor, top of a machine or pump liquids of higher viscosity.

The Type of Chemical

This is ideally a vital consideration, needed to ascertain that the tube materials of the pump are compatible with the chemical liquid to be pumped. Additionally, it’s imperative to determine whether the fluid is combustible or flammable.

Specific Viscosity and Gravity

Varying pumps have varying capabilities when it comes to pumping liquids with a viscosity higher than 1cP or gravity greater than 1. These capabilities are based on the design of the drum pump as well as the motor driving the machine.

The Temperature of the Liquid to Be Pumped

Drum pump tubes tend to have an upper-temperature limit. This, of course, depends on the tube series, length and construction.

Motor Preference

You should ideally determine whether or not the location has a certain motor preference- air, explosion or electric. For the latter, you should assess what voltage is needed.

Size of the Container

Drum pump tube lengths change depending on the container’s size. For instance, a conventional 200-litre drum utilizes a pump tube of 100cm. Tanks and IBCs often call for longer lengths while 15 to 30-gallon containers utilize smaller lengths.

Stage 2: Pick the Right FTI Pump Series & Tube Material

Once you know the application requirements, the next step is to pick the right FTI pump for the task. Begin with the outer tube material; these come in stainless steel, CPVC, PVDF and polypropylene.

You should use a chemical resistance guide to pick an outer tube material that’s resistant to the liquid you intend to pump. You will come across this guide on our useful information section, or by simply googling.

Keep in mind that every pump tube has other materials that will come into contact with the liquid in addition to the outer pump one.

Stage 3: Pick The Right FTI Motor

You should use the motor preference info to pick a motor that best matches your needs. Ensure that if the fluid to be pumped is flammable, you will have to use explosion-proof air or an electric motor on a tube that’s made from stainless steel.

Stage 4: Pick Your Accessories

Static Protection Kit – this is for the safe transfer of combustible or flammable fluids when utilised with stainless steel tube pumps and explosion- or air-proof electric motors.

Hose – flexible PVC

Flow Meters – to allow for precise measurement of the fluid being pumped.

Drum Adapters – to guarantee a tight fit of the drum tube.

Filter – to get dry and lubricated air supply for the motors.

Strainers – to protect the drum pump from damage by foreign elements.

Nozzles – for controlling liquid flow.
