Operation Drum pumps
Most drum pumps utilize positive displacement to move fluids. Positive displacement pumps use expanding and contracting cavities to move fluids. They produce a constant flow suited for applications requiring high pressures (and low flow rates) with high viscosity fluids.
Materials Drum pumps
The base material of a drum pump is important to consider, as it affects the type of media that can be handled effectively.
System fluids may be abrasive, acidic, caustic, tacky, very hot, very cold, or otherwise hazardous.
Base materials such as cast iron, plastic, and stainless steel possess different advantages for handling these various characteristics.
- Plastics may be the least expensive base materials and provide excellent corrosion resistance and protection from a broad range of chemicals.
- Stainless steel alloys provide protection against chemical and rust corrosion and have higher pressure ratings than most plastics.
- Cast iron provides excellent strength and abrasion resistance, with high-pressure ratings.
What is a pneumatic drum pump?
A pneumatic drum pump is operated by an air-driven motor. It achieves mechanical work by expanding compressed air. It then converts compressed air energy to mechanical work through either a linear or rotary motion.
Pneumatic drum pumps are particularly suitable for intermittent and short-term operations. Like all other variations of drum pumps, pneumatic drum pumps are used to transfer a liquid from one drum into another. These pumps consist of a pneumatic drive motor and a pump tube.
This pump tube stands as a suction tube vertically in the bunghole of a barrel or an IBC container. The immersion tube fits through the drum’s opening and is often sealed to the top of the container.
The ‘pump’ itself is located within the lower end of the immersion tube. The pumped fluid flows between the sleeve and the tube to the discharge port at the motor end.
What can a pneumatic drum pump be used for?
Pneumatic drum pumps are commonly used in applications that require explosion-proof pumps. In these instances, power is required for large volume handling, and electric or manual drum pumps are not appropriate.
Pneumatic drum pumps with conductive stainless-steel tubes are typically used for transferring flammable media of different hazard classes in hazardous environments. These pneumatic drum pumps are labeled with ATEX approval.
These drum pumps can also pump the following liquids:
- Hydrochloric acid
- Sofa lye
- Formic acid
- Sal ammoniac
- Photo developer
- Lime potash
- Fixing baths
- Acetic acid
- Phosphoric acid
- Fruit acids
- Nitric acid
- Hydrofluoric acid
- Bleaching solution
- Lactic acid
- Boric acid
- Chromic acid
- Soap solutions
They are also useful in mining, food and beverage, and chemical industries.
Advantages of pneumatic drum pumps
The main advantage of pneumatic drum pumps is the ability to safely transfer dangerous liquids from containers – avoiding injuries, chemical splashing, leaks, and toxic fumes. Further advantages include:
- Lightweight and portable
- Modular design – a variety of immersion tubes suitable for varying container sizes
- Interchangeable pump tubes allow for repurposing of the same pneumatic motor
Limitations of pneumatic drum pumps
Pneumatic drum pumps can limit operators in the following ways:
- It May be designed or constructed for one type of fluid, therefore might not be able to discharge another due to differences in viscosity or chemical incompatibility.
- Unable to pump liquids with high particulate matter or slurries
Electric Drum Pumps
When you’re working with aggressive materials, you need to be absolutely sure that the tools you’re using are up to the job. Our products provide you with explosive protection and fortification against corrosion so that you can be confident about your workplace safety and environmental protection priorities.
Electric drum pumps are motor-driven devices powered directly from an electrical outlet or by an internal rechargeable battery to draw fluids out of a container.
They generate consistent flows at a higher rate than hand drum pumps to dispense or transfer moderate to large amounts of fluid. They’re also more energy-efficient thematic pumps.
Hand-Operated Drum Pumps, sometimes referred to as manual hand pumps, are safe and convenient drum pump suitable for emptying drums and containers.
These pumps are generally more cost-effective, as there is no motor attached, and they require the operator to create the ‘pumping’ action.
What are hand-operated drum pumps?
Hand-operated drum pumps are one of the simplest and most economical pump solutions. They are operated manually by a lever that sits at the top of the immersion tube, on the outside of the container. The tube fits through and is often sealed, to the opening on the top of the container.
What applications are hand-operated drum pumps suitable for?
As hand-operated drum pumps are available in a variety of different materials, including seals, they are suitable for pumping acids, alkalies, and water-based chemicals.
Advantages of manual drum pumps
The main advantage of hand-operated drum pumps is that it eliminates any risks associated with transferring fluids from containers. Besides this key advantage, hand-operated drum pumps also offer operators the following:
- Compatibility: hand-operated drum pumps are available in a variety of materials of constructions… manual drum pumps are compatible with a various attachments allowing you to alternate tubes depending on the size of your drum.
- Flexibility: most hand-operated drum pumps come with a telescopic pump tube which allows them to be used in different drum sizes.
- Low-cost pumping solution: as manual drum pumps do not have an electric or pneumatic motor as such, they are a low-cost pumping solution for those looking for a more economic option.
Disadvantages of hand-operated drum pumps
One of the main disadvantages of hand-operated drum pumps is the physical exertion required to generate the ‘pumping’ action. It can also be time-consuming to transfer large amounts of liquid.
There may also be restrictions with certain applications, particularly those with high-risk liquids like hazardous, corrosive, or flammable.
Applications Drum pumps
Drum pumps are used in fluid transfer processes in the chemical, water, marine, and paper industries, among others.
They may be mounted on large tanks and may transfer corrosive media, cleaning solutions, saltwater, or slurries to storage tanks or treatment systems.
Drum pumps are a popular choice when transferring a variety of chemical, hazardous, and flammable liquids.
