What is a barrel drain pump?
Barrel pump or barrel pump, which is also known as barrel pump or drum pump, for quick and safe discharge and transfer of all types of fluids such as water or all types of chemical, acidic and alkaline fluids, solvents, Fuel and… with different viscosity and chemical properties are used from tanks or barrels in various industries such as chemical factories, food processing factories, etc.
The driving power of these pumps is usually manual, electric or pneumatic and they are selected according to the type of fluid, usage and available power source. These portable pumping equipment are available in metallic and non-metallic (plastic) materials for minimal corrosion and damage when used for corrosive fluids.

How the types of barrel discharge pumps work:
Many fluids used in manufacturing and processing plants are delivered in barrels of 100 liters or more. In addition, many industries store their raw materials in large tanks. The barrel drain pump enables the transfer of liquids from these containers in a safe and effective manner. The application of the barrel pump is usually simple fluid transfer and pumping, so high flow rates and pressures are usually not required. However, there are models of this pump for special applications such as high pressure or high viscosity fluid pumping.
Manual barrel discharge pumps make fluid suction and transfer possible using a simple mechanism. The pump handle rotates using hand power to rotate the crank connected to the rotor inside the chamber. With the movement of the rotor and as a result of the rotation of the vanes, the air molecules are removed and a vacuum is created, then the fluid is sucked into the tank through a submerged tube and directed out of the container. These pumps are used for small volumes and are suitable for places where electricity is not available.
The materials of these pumps are usually stainless steel and aluminum or plastics such as polyester, polyphenylene sulfide, polypropylene and PVC. The inlet size of this equipment can vary from 0.5 inches to 1.5 inches. Manual barrel pumps offer easy, leak-free, spark-free pumping and are cheaper and less costly than electric and pneumatic barrel pumps and are used for pumping simple fluids and all types of fuel.

Manual Barrel Drain Pump Components
In some models, the transmission of power to the vanes in the pump housing is done by gears. In other examples, the pump drum consists of three parts: the motor, the immersion tube and the pump. The motor is placed on top of the immersion tube in the outer part of the barrel or tank and is responsible for supplying power to the pumping system. The immersion tube is placed in the fluid and has the task of transferring power and transferring the fluid at the same time, whose height should be equal to the height of the barrel.
The electric barrel drain pump works by using an AC or DC electric motor with different voltages. When the engine is turned on, the torque is transferred to the centrifugal impeller at the end of the pump through the shaft inside the tube, which is sealed by another tube, and the rotation of the impeller creates a vacuum and fluid suction. The fluid moves between the shaft tube and an outer tube and flows towards the discharge port.
The electric pull barrel pump is used for high volume and low viscosity fluids such as alcohols, acids, light petroleum derivatives, drinks, etc. For fluids with higher viscosity such as ink, edible and industrial oils, honey, sauce, paste, paint, fluids containing solids, gel, silicone, polymer, etc., a spiral stator is used instead of a centrifugal impeller, and the task of fluid transfer It is the responsibility of the spiral.
In the pneumatic barrel pump model, an air compressor is used instead of an electric motor, in other words, the air acts as a fluid driver, and the energy of the compressed air in a linear or rotational manner causes the mechanical work of the diaphragm and the transfer and pumping of the fluid. These pumps are suitable for intermittent operation and pumping flammable materials and use in hazardous environments and must have ATEX approval. ATEX is a European certification that is given to equipment that has been tested and evaluated by official institutions for working in an explosive environment . Other uses of pneumatic barrel discharge pumps are their use in wet or dusty and dirty environments.
Electric or pneumatic barrel discharge pump components:
In other cases, a diaphragm pump is used to pump and empty the barrel . This type of pumps use compressed air and diaphragm reciprocating function to pump fluid, which are suitable for pumping thick and high-viscosity fluids and such flammable fluids and use in explosive environments.

If the fluid is grease or chemical paste, or in other words thick fluid, plates with a circular section that are moved by hydraulic or pneumatic force are used. These plates are sealed by special bands with the barrel wall and apply the pressure force supplied by a hydraulic or pneumatic jack to the fluid so that the fluid moves towards the discharge valve.

The barrel discharge pump consists of several components. The parts in contact with the fluid in this pump, such as pipes, propellers, etc., must be resistant to corrosion and if the fluid is flammable or combustible, they must be safe at operating temperature. The pump pipe and other parts are usually made of polypropylene, stainless steel 316, PVDF or CPVC.
| sex | Application |
|---|---|
| Polypropylene | Acids, alkyls, detergents, etc. up to a temperature of 50 degrees Celsius |
| PVDF (polyvinylidene fluoride)
CPVC (chlorinated polyvinyl chloride) |
Chlorine bleach, cermic acid, hydrofluoric acid, nitric acid, sulfuric acid, etc. up to 90 degrees Celsius |
| aluminium | Petroleum products such as diesel, hydraulic oil, gearbox oil, engine oil, mineral oil, etc. |
| 316 stainless steel | Corrosive and flammable fluids, use in high pressures |
Application of barrel pump:
Most of the barrel pump manufacturers offer a wide range of power sources, either in terms of being single-phase or three-phase, and in terms of the type of power (electric or pneumatic). A hand pump drum can be used when electricity is not available, or explosion-proof or pneumatic motors should be used if the fluid is flammable.
Due to the fact that there are tanks with different dimensions, different pipe lengths are available for tanks with different depths. For example, a 100 cm pipe is needed to empty a standard 200 liter barrel.
When choosing a barrel drain pump, attention should be paid to the type of fluid in terms of corrosion, viscosity, working environment in terms of temperature and humidity, etc. It is also necessary to ensure the chemical compatibility of the material used in the pump parts with the pumped fluid.
In general, the barrel pump is used to transfer and discharge all kinds of chemicals such as acids, bases, solvents and alcohols, detergents such as bleaches and softeners, all types of fuel and flammable substances such as gasoline, oil and diesel, all kinds of industrial oils and Edibles such as hydraulic oil and motor oil, grease, liquid gases, edibles such as honey, paste, essential oil and juice, all types of glue and paint, resin, latex, polyester, etc. in various industries such as chemical and petrochemical industries, pharmaceuticals It is used in food industry, textile industry, water and sewage treatment, power plants.
Advantages and Disadvantages:
The advantages of the barrel discharge pump include the following:
1) easy transportation and their maintenance is simple and low-cost due to their simple construction.
2) Barrel discharge pumps are compatible with all types of fluids such as chemicals, fuel, oil, etc.
3) For these pumps, ATEX motors for flammable liquids and FDA approved models for food and pharmaceutical industries are available in the market.
4) These equipments reduce many risks caused by manual handling of containers and barrels, including chemical splashes and toxic vapor leaks.
5) Drum pump designs are available for all types of fluids with different viscosities. Centrifuge models with one or more propellers are used for fluids with low viscosity, and positive displacement pumps such as piston pumps or monopumps are used for fluids with higher viscosity.

And the disadvantages of the barrel pump :
- The barrel discharge pump is assembled for a barrel with specific dimensions and containing a fluid with a specific chemical property. For example, the length of the immersion tube in a pump and for a 220 liter barrel may not be long enough for other barrels, or the pump materials may not be chemically compatible with other fluids. However, the parts are designed and assembled in such a way that they can be easily replaced and repurposed.
- Barrel pumps are limited in operating capacity, flow and pressure, and the more viscous the fluids are, or in other words, the more viscous this limitation increases.
- The space between the outer and inner tube in which the shaft is located is limited and the fluid must flow through this part, which causes the inability to transfer fluid containing large solid particles.
