Pumps for hazardous materials
Safe handling of hazardous substances requires special pumps to minimise risks and increase efficiency. In this guide, you will learn which aspects need to be considered when selecting and using pumps for hazardous materials and how the specific requirements of different materials and applications can be taken into account. We provide a comprehensive overview of how to select the right pump drive, how to work with different containers and how to handle waste oil. All our specialised pumps are designed to safely and efficiently handle specific media types, whether it's chemicals, oils, solvents, flammable liquids or others. They are engineered to help reduce spills, contamination and unnecessary operator exposure, and are widely used across industries such as chemical manufacturing, pharmaceutical production, water treatment and other sectors, where hazardous substances need to be handled accurately and safely.
What are pumps for hazardous materials used for?
It is often necessary to fill hazardous materials precisely - for example, from a large container into a smaller container. With large containers in particular, it is almost impossible to tip or tilt them for filling without risking spillage or having to apply a lot of force.
To give you the greatest possible freedom of action in your daily work with hazardous substances, the DENIOS range includes a large selection of different pumps that are resistant to many of the most common hazardous materials. Electric pumps and pneumatic pumps enable safe and accurate filling from drums, IBCs or other large containers.
Using the right pump helps reduce the need for manual handling, while also improving accuracy and minimising the risk of spills during transfers. This not only supports better workplace safety and environmental protection, but can improve overall productivity by making routine filling tasks faster and more consistent.
What must be considered for pumps for hazardous substances?
Pumps for hazardous materials enable safe and accurate filling from drums, e.g. into smaller containers. They are available in different versions depending on the requirements. The container size, the desired delivery rate and, last but not least, the suitability of the pump for the medium to be filled are important factors when selecting the optimum product. The viscosity and chemical properties of the media play a decisive role in choosing the right pump. There are pumps for mineral oil products, pumps for chemicals, acids and alkalis, as well as pumps for flammable liquids.
Before selecting a pump, always consult the Safety Data Sheet (SDS) for the substance being handled to confirm chemical compatibility, recommended transfer requirements and any other specific handling precautions. The ‘Technical Data’ panel on each of our individual pump product pages details which media each pump is suitable for, so you can be sure of finding a suitable solution for your exact requirements.
Which pumps are appropriate for which materials?
The most important criteria when selecting a suitable pump is the fluid to be pumped. Liquids vary greatly in their viscosity and chemical properties. There is no pump that can pump all media satisfactorily - and the pump must of course also be resistant to the medium to be filled. Depending on the requirements, pumps are therefore optimised for different hazardous materials.
Which pump drive is required for the application?
Manual, electric, battery-powered or pneumatic? Different drive systems are available depending on how often and for what quantities you want to use your pump. While electric and pneumatic pumps are generally designed for larger containers and primarily enable large quantities to be filled quickly, manual pumps are more suitable for the occasional filling of smaller quantities. The viscosity of the media to be pumped also has a significant influence on the choice of drive system. When deciding between an electric, battery-operated or pneumatic pump, the connections available in the business are important. Pneumatic pumps can often achieve the best results with materials that are particularly difficult to pump. Choosing the right pump drive involves balancing productivity, operating costs and the demands of your application. An electric drum pump is often the preferred choice for frequent tasks, while manual pumps can offer a cost-effective solution for more occasional use. As mentioned above, higher-viscosity media are not suitable for manual pumping, so this should also be taken into consideration. Before making your selection, consider:
The viscosity of the liquid being transferred
Whether mains power, compressed air or battery operation is most practical
The expected transfer volumes and required flow rate
Whether hazardous area classifications or ATEX requirements apply
We have summarised the most important advantages and disadvantages of the various pump drives below.
Electric pumps
An electric drum pump is a tried and tested classic. They are ideal for frequent liquid transfer from drums, IBCs and other industrial containers where speed, consistency and ease of use are priorities. Electric drum pumps are widely used across manufacturing, chemical processing, pharmaceutical production and other industries that require efficient, accurate and regular liquid transfer with ergonomic operation.
| Advantages |
|---|
| Efficient and compatible with almost all materials |
| Efficient and compatible with large delivery volumes |
| Suitable for frequent and/or continuous operation |
| Disadvantages |
|---|
| Power connection required on site |
Battery pumps
Battery pumps enable mains-independent, cordless filling and decanting, making them ideal for mobile applications, multiple workstations and locations where no mains connection is available. Battery pumps are suitable for low-viscosity, aqueous to slightly viscous media. To avoid charging breaks, rechargeable batteries can be kept in stock and easily replaced, making battery runtime an important consideration where frequent or prolonged pumping is expected.
| Advantages |
|---|
| Mobile and flexible in use |
| Completely independent of existing connections |
| Efficient and compatible for frequent use with low-viscosity, aqueous to slightly viscous media |
| Disadvantages |
|---|
| Not suitable for very viscous materials |
Pneumatic pumps
A pneumatic pump is particularly powerful and is, therefore, often the most appropriate choice for media that are particularly challenging to pump. These include substances with extremely high viscosity, abrasive substances or substances containing solids. Their robust design also makes them a reliable choice for demanding industrial environments and continuous operation.
| Advantages |
|---|
| Suitable for extremely viscous and difficult to pump materials |
| Efficient and compatible for large delivery volumes |
| Suitable for frequent and/or continuous operation |
| Disadvantages |
|---|
| Pneumatic connection required on site |
Manual pumps
Manual pumps work with hand or foot operation. They are a cost-effective alternative for occasional use and for pumping small quantities of low-viscosity materials. Even the removal of small quantities from larger containers, such as drums, is possible. Depending on the model, the immersion tube can be adjusted to the container depth, while their simple design also makes them easy to transport between different work areas.Â
| Advantages |
|---|
| Mobile and flexible in use |
| Completely independent of existing connections |
| Cost-effective |
| Disadvantages |
|---|
| High effort and time required for large delivery volumes |
| Not suitable for viscous materials |
| May not be suitable for high delivery volumes |
| Not suitable for continuous use |
What is the right container for the application?
The container from which the liquid is to be pumped is also decisive for the pump selection. Depending on whether you want to pump from small canisters, drums or 1,000 litre IBCs, the pump must have the right immersion depth and delivery rate. The pump connection must also match the thread of the respective container. We offer you a large selection of different pump types - from mini pumps to tank pumps. If the thread does not fit, you can use a thread adapter.
Pumps for specialised requirements
Specific applications will require exactly the right pump for the job. This is why you will find several pumps for highly specialised requirements in the extensive DENIOS range. Examples include gas-tight pumps for odourless filling of strong-smelling substances such as ammonia, or mini pumps for the safe filling of small quantities in laboratories.Â
Our range also includes mobile pump systems that combine the performance of an electric drum pump with optimum flexibility. Pumps suitable for dry running are the solution for applications where draining from below (floor draining) is required. These specialist pumping solutions are widely used across laboratories, chemical manufacturing, pharmaceutical production, water treatment, food production and other industrial environments.
Which pumps are suitable for waste oil?
If you want to transfer used oil from a large container to a smaller one, we recommend electric pumps or pneumatic pumps. Various models are available depending on the container size and application area. Pneumatic and electric drum pumps are particularly suitable for transferring waste oil, as they can efficiently handle viscous oils and other high-viscosity substances. They are also efficient at high flow rates and are suitable for continuous operation.
