When it comes to wood preservation, utilising the latest pump technology can truly unlock the hidden potential of your timber. Enhancing the strength and beauty of your wood is essential for ensuring its longevity and aesthetic appeal. Through innovative pumping systems, you can effectively treat and protect your timber against damaging elements such as rot, pests, and decay, extend the lifespan of your wood, enhance its structural integrity, and preserve its natural beauty.
Wood is a versatile and renewable material and preservation includes the process of treating wood to enhance its durability and resistance to these threats. By preserving wood, you can significantly extend its lifespan and reduce the need for frequent replacements, saving both time and money in the long run.
The application known as tanalising, pressure treatment or tanalisation, is a process in which wood is treated with a wood preservative called Tanalith E. The treatment involves placing the wood in a vacuum-sealed tank and applying pressure to force the preservative deep into the wood. This ensures that the chemicals absorb thoroughly into the wood, making it highly resistant to rot, mould, fungi, insects, and extreme weather conditions. Tanalised timber has a long lifespan and can last around 30 years without additional treatment and is safe for use around children and pets and is a durable and versatile wood option.
In the tanilising industry, there are two common methods: dipping and high-pressure treatment. Dipping provides limited durability, while high-pressure treatment offers better long-term results.
Using the high-pressure method, wood is loaded into a pressure container, and put under an initial vacuum by one of our liquid ring vacuum pumps, to make sure that wood cells are evacuated of air and then filled with a treatment chemical (such as Tanalith E). The vessel is then pressurised (by use of one of our vertical multi-stage centrifugal pumps) to ensure the chemical reaches deep within the grain of the wood.
Liquid Ring Vacuum pumps are particularly suitable for treating porous woods or materials with irregular shapes. The vacuum pressure ensures that the preservatives reach deep into the wood, eliminating air pockets and maximizing treatment effectiveness.
Utilising pumps means that a thorough process makes sure that the wood is properly treated and ready for its final destination by removing excess chemicals through a second vacuum stage and allowing the wood to dry to ensure that the timber is prepared for its intended use. We like to think that this attention to detail and commitment to quality sets CDR Pumps apart in the wood preservation industry.
Unlock the potential of pump technology in wood preservation and take your timber projects to new heights. By embracing innovative pumping systems, you can safeguard your wood against the damaging effects of rot, pests, and decay, enhancing its structural integrity and preserving its natural beauty for years to come.

We are delighted to announce that CDR Pumps has been shortlisted as a finalist for the Chemicals Northwest Supplier to the Chemical Industry Award 2026.
Being shortlisted is a fantastic recognition of the work our team does every day to support the UK chemical industry with innovative, reliable and safety-focused pumping solutions….
A long-term customer, who operates within the chemical manufacturing industry, approached us because they needed to modernise and improve control over their tanker unloading processes. Their existing systems operated by either using the “blowing method” or relying on pumps mounted on the tankers and weren’t particularly reliable, consistent, or safe, especially when it comes to handling aggressive chemicals such as 96% Sulphuric Acid and 50% Hydrogen Peroxide.
Chemical pumps improve the performance of your fume scrubbers!
It’s a bold statement, but true. Industrial ventilation plays a key role in workplace safety and regulatory compliance in manufacturing plants. Industries like chemical processing, pharmaceutical manufacturing, and metalworking rely on robust (and reliable) ventilation systems to remove harmful fumes, particulates,…
