What is it?
DrumQuik PRO is a closed chemical dispensing systems designed to facilitate safe, easy and economic extraction of chemicals from plastic drums, jerry cans, and IBCs. This chemical management system is comprised of two major components; a low-cost and recyclable “drum insert assembly” that combines into one integrated unit a bung closure and a dip-tube. The drum insert assembly seals the container for transport from chemical packager to the end user site.
The second component is a rugged, reusable quick disconnect coupler (dispense head) that is installed at the point-of-use. The coupler incorporates an automatic shut off valve which prevents chemical media from leaking out when it is disconnected from the drum insert during container change-outs. It also ensures that both sides are sealed from point-of-origin to point-of-use. The coupler also incorporates a vent port for controlled venting of the container.
What problem or need does is address?
In many different industries and applications food products or dangerous chemicals are transferred from their shipping containers via open dispense systems that are susceptible to spillage, waste and noxious vapor release. It is often left up to the end user to figure out how to get the chemical from the container to the end use process. As a result, personnel, equipment and the environment are needlessly exposed to hazardous chemicals and the fumes they generate. DrumQuik dispensing systems were developed to provide the chemical packager and their customers a way to solve this problem by allowing the chemical packager to supply the container in a “ready to dispense” state to which the end user can easily and safely connect. DrumQuik systems allow almost any open dispensing system to be converted to a closed system, thereby facilitating the delivery of chemicals from rigid containers to end use applications while minimizing exposure.
What systems are typically used today to dispense hazardous chemicals from drums?
Common methods today include different versions of an open system, in which chemicals are either poured or pumped out of the drum. In semi-closed dispensing systems, a dip-tube draws chemicals from vertically oriented containers using an attachable hand or electronic pump. While a step in the right direction, the dip-tube is reused from one drum to the next, exposing the end-user to drips, leaks and fumes during transfer.
What is a closed dispensing system?
A closed system is specifically designed to minimize worker exposure to chemicals and fumes at all phases of chemical handling. This includes during the connection to the container, during chemical dispensing, disconnection and disposal. A key element of DrumQuik dispensing systems that makes closed dispensing possible is an integrated closure (bung plug) and dip-tube assembly that is shipped as part of the drum package, eliminating the need to remove and re-install the dip-tube at point-of-use. The drum insert assembly can be reused if desired but it is so cost effective that it can be treated as part of a single-trip disposable package.
Closed systems, such as DrumQuik dispensing systems, also feature additional safety mechanisms such as a built-in vent port which allows users to safely control and manage venting of the container instead of allowing fumes to vent directly to the atmosphere. The vent port can be used to either route fumes to a vent hood, or be outfitted with a filter to prevent contamination or a vent check valve which prevents harmful vapors from contaminating the work environment while allowing “make-up” air into the container (and protecting against spillage in a “tip-over” situation). The vent port can also be used to connect a pressure source to speed chemical flow without releasing vapors or connected to a blanket gas source (N2, CO2, etc.) to protect sensitive liquids, such as edible oils, fragrances or other chemicals from oxidation resulting from contact with air.
Why is a closed dispensing system important?
Closed systems are important because they greatly minimize the potential for hazardous chemical and vapor exposure. OSHA and other safety initiatives are driving the trend toward closed-system chemical handling, requiring that media be transported from container to point-of-use in a closed manner. Ultimately, the safest way to remove chemicals from a rigid container is from the top while the container is vertical, using a closed dispensing system. DrumQuik dispensing systems are designed to maximize chemical handling safety in this type of environment.
What are some typical applications that might benefit from a closed-system?
One example is an industrial laundry facility that deals with highly toxic chemicals, such as sulfuric acid. In this application, all wastewater must be treated to a neutral PH level to comply with OSHA and EPA regulations. Having a closed system allows the end-user to neutralize the wastewater and eliminate direct contact with sulfuric acid. Another example is non-hazardous food applications. A closed system prevents messy spills and/or oxidation of edibles, i.e. olive oil, (which can become rancid when exposed to air) thereby extending their product shelf life. A third example is in the developing Diesel Exhaust Fluid (DEF, AdBlue) markets where high purity grade urea is used in a Selective Catalytic Reduction (SCR) process in diesel engine vehicles to meet EPA emission standards. The urea is delivered to filling locations using 55 gallon (200 l) drums and larger IBC containers. A low-cost integrated quick connect dip-tube system is required to make connection easy for station/site managers while protecting the integrity of the urea.
What industries will find the DrumQuik PRO useful?
The system is ideally suited to industries with cost-sensitive, one-way and single-use container applications, including institutional cleaning; paint and coatings; pharmaceutical media; fragrances and flavorings; agricultural fertilizer; oils and syrup transport; and acids, caustics and solvent delivery. In summary, the DrumQuik PRO will be useful for virtually any industry where chemicals are drawn from a jerry can, plastic drum or IBC.

Does the DrumQuik PRO meet international standards?
Designed to be compatible with all types of common drums and containers, DrumQuik systems were developed to meet United Nations and U.S. Department of Transportation approval standards (Title 49 CFR, Section 178) for the transport of dangerous materials. While DrumQuik PRO cannot be UN/DOT approved by itself, it is designed to be capable of approval with jerry cans, drums and IBCs as part of the “package” and have successfully passed UN/DOT tests with common 5 gallon (20 l) containers, 15, 30 & 55 gallon drums and larger 275 gallon (1000 l). DrumQuik systems are available in both North American and European drum thread sizes based on ISO standards and are produced in materials that are compliant with United States Food and Drug Administration (FDA standards).
Is the DrumQuik PRO cost effective?
Absolutely! The coupler is made of high-quality, FDA compliant virgin polypropylene material engineered to be rugged and withstand thousands of connections. The drum insert assembly is made of FDA compliant virgin polyethylene (HDPE), designed to be used with cost-sensitive one-way container applications and can be incorporated into the cost of the drum without significantly adding to the unit cost. In addition, the polyethylene drum insert assembly can be recycled together with the drum. It can also simply be shipped back to the manufacturer along with the drum.
What bung threads are available?
2” Buttress (ISO G2 x 5), commonly used in plastic drums in North America
Can I use my standard bung wrench to install the drum insert assembly?
Yes. A DrumQuik torque tool adapter is required to mate to the drum insert assembly but the adapter has provisions to accept a standard ½ inch drive torque wrench as well as common bung wrenches.
Is the installation torque different than that of standard bung plugs?
The installation torque is very similar to accepted practice and will vary slightly depending on thread style and container type. Colder testing indicates that settings from 15 – 25 ft-lbs (20 - 34 N-m) are adequate to seal but recommends that the actual setting be verified by the customer for each application.
Are special tools required by the end user to connect to the coupler to the drum insert assembly that arrives pre-installed in the drum?
No. A standard Philips #4 or flat blade screw driver (or even a coin) can be used to remove the shipping plug. Thereafter the coupler can be easily connected by simply turning the lock ring 2 turns in the clockwise direction (a firm “stop” can be felt when fully engaged).
Can I use tamper evident caps to protect my chemical integrity?
Yes. The drum insert assembly does not protrude above the drum bung therefore standard tamper evident caps can be used with DrumQuik systems.
When does the shut off valve in the coupler open?
The shut off valve does not begin to open until the lock ring has been engaged by approximately ½ turn and is not fully opened until the lock ring has been fully screwed down to its physical stop.
Will any pressure be vented from the drum prior to disconnect?
Yes, when disconnecting the coupler from the drum insert assembly the pressure inside the drum is first vented to atmosphere, then as the lock ring continues to be unscrewed the shut off valve is closed, and lastly the coupler may be disconnected from the drum insert assembly. Colder recommends that the user wait 3 – 5 seconds to allow any remnants of liquid to drain prior to finally removing the coupler.
How do I connect the coupler to my plumbing system?
The coupler is available with a ½” male NPT. Colder offers a limited selection of both hose barb and compression fittings that can be used to connect to the system tubing. Alternatively, any fitting with a mating female thread can be used.
What type of pump can be used with the system?
DrumQuik dispensing systems are connected to the downstream system via a length of tubing; therefore the pump style options are almost limitless. DrumQuik systems work in both high flow “transfer” applications as well as low flow “dosing” applications.
What is the flow capacity of the system?
DrumQuik dispensing systems can be used in applications varying from a few drops per hour to applications requiring 15 gpm (56 lpm) or more. Flow capacity can vary widely depending on fluid viscosity and system configuration.
How can I prevent fluid from flowing back into the container when the pump is turned off?
A suitably sized, low pressure back check valve can be installed downstream of the coupler to prevent backflow. A foot valve can be installed in the end of the dip-tube to prevent back flow.
