Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. [1] Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside. Drum pumps range from simple siphon based devices to sophisticated highly-engineered machinery.
Low cost manual pumps are used when product dispensing is periodically needed. Crank and lever driven pumps are available. Double-action piston drum pumps can be self priming, delivering liquid on both the forward and the back stroke.
Unlike a submersible pump with the motor submerged, a drum pump has a drive motor above the container. Electric and pneumatic motors are available. The motor is attached to the vertical shaft at the top of the tube outside the drum and the pumping element is located at the end of the shaft inside the drum. This configuration allows the drum to be emptied without tipping and so reduces the risk of spills and operator injury. [2]
Some materials are solid at ambient temperatures and must be melted to allow pumping. This might include open-head drums of hot-melt adhesive, heavy grease, etc. Several systems have been developed which use a heated platen placed on the material; the melted material is then pumped through a heated hose to its destination.

A washing machine is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid, powder, or dehydrated sheet form, to the wash water.
A submersible pump is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump and the fluid surface. Submersible pumps push fluid to the surface, rather than jet pumps, which create a vacuum and rely upon atmospheric pressure. Submersibles use pressurized fluid from the surface to drive a hydraulic motor downhole, rather than an electric motor, and are used in heavy oil applications with heated water as the motive fluid.
Spray painting is a painting technique in which a device sprays coating material through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles.
Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist.
A water dispenser, known as water cooler, is a machine that dispenses and often also cools or heats up water with a refrigeration unit. It is commonly located near the restroom due to closer access to plumbing. A drain line is also provided from the water cooler into the sewer system.
A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream. As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Vapor compression chillers may use any of a number of different types of compressors. Most common today are the hermetic scroll, semi-hermetic screw, or centrifugal compressors. The condensing side of the chiller can be either air or water cooled. Even when liquid cooled, the chiller is often cooled by an induced or forced draft cooling tower. Absorption and adsorption chillers require a heat source to function.
In electronics, desoldering is the removal of solder and components from a circuit board for troubleshooting, repair, replacement, and salvage.
A wax motor is a linear actuator device that converts thermal energy into mechanical energy by exploiting the phase-change behaviour of waxes. During melting, wax typically expands in volume by 5–20%.
An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc.
Intermediate bulk containers are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, semi-solids, pastes, or solids. The two main categories of IBC tanks are flexible IBCs and rigid IBCs. Many IBCs are reused or repurposed.
A spray bottle is a bottle that can squirt, spray or mist fluids.
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.
An instant hot water dispenser or boiling water tap is an appliance that dispenses water at about 94 °C (201 °F) (near-boiling). There are hot-only and hot and cool water models, and the water may be filtered as well as heated. Instant hot water dispensers became popular in the 1970s. Instant hot water dispensers are very similar to portable shower devices; the latter is fitted with a heating element and quickly heats up water, once a switch has been activated.
Scheugenpflug AG is a manufacturer of adhesive bonding, dispensing, and potting systems for synthetic resins or thermally conductive pastes. In this special segment only few enterprises of super regional importance are active in the whole world. Target industries include automotive and electronics industry, telecommunications engineering, medical technology and the chemical industry.
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers, petrol pumps, or gas pumps.
A Drum handler is a piece of mechanical equipment that is used to securely grip, lift and transport cylindrical modules such as steel drums, barrels, plastic drums and fiber drums. It has spring-loaded metal arms to create a tight and secure grip. This equipment is commonly used in chemical and petroleum industries, as well as industries that require shipping and storing of cylindrical modules.
A media dispenser or a culture media dispenser is a device for repeatedly delivering small fixed volumes of liquid such as a laboratory growth medium like molten agar or caustic or volatile solvents like toluene into a series of receptacles. It is often important that such dispensers operate without biological or chemical contamination, and so must be internally sealed from the environment and designed for easy cleaning and sterilization before use. At a minimum, a media dispenser consists of some kind of pump connected to a length of discharge tubing or a spout. Dispensers used in laboratories are also frequently connected to microcontrollers to regulate the speed and volume of the medium as it leaves the pump.
A foam pump, or squeeze foamer and dispensing device is a non-aerosol way of dispensing liquid materials. The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The parts of the foam pump, mostly made from polypropylene (PP), are similar to those of other pump devices. The foaming pump often comes with a protective cap.
A pump dispenser is used on containers of liquids to help dispensing. They might be used on bottles, jars, or tubes. Often the contents are viscous liquids such as creams and lotions. Some are metered to provide uniform usage. Some mix contents from two or more sources prior to dispensing.
A fuel container is a container such as a steel can, bottle, drum, etc. for transporting, storing, and dispensing various fuels.
