Flying the flag for british manufacturing
BlueDiamond®, a brand by Charles Austen Pumps Ltd, has been proudly manufacturing pumps and HVACR solutions for nearly 75 years. As a British company with a rich engineering heritage, we have grown from specialising in condensate removal to delivering a comprehensive range of innovative HVACR technologies and solutions. All our products are meticulously designed, tooled, tested, and manufactured in-house, reflecting our unwavering commitment to quality and backed by ISO 9001 certification.
Our journey began with our exclusively patented Rotary Diaphragm technology, which laid the foundation for further innovation, including our uniquely patented GyRok™ pumping principle—launched with the MicroBlue® in 2017. These proprietary advancements have driven the expansion of our product portfolio, which now includes intelligent refrigeration drainage systems, smart sensors and detectors, custom OEM solutions, and a full range of mounting accessories. From concept to packaging, every stage of production is handled by our skilled team, who take immense pride in every product leaving our facility. Continuous investment in training and cutting-edge machinery ensures we remain at the forefront of a fast-evolving industry.
PRECISION MANUFACTURING
Manufacturing excellence and innovation are at the core of everything we do at BlueDiamond®. With a strong foundation in Original Equipment Manufacturing (OEM), we’ve propelled ourselves ahead of the competition in design and global production capabilities. We don’t just assemble pumps—we design and build them from the ground up, ensuring unmatched reliability and performance. This commitment to quality is why we offer a standard 3-year warranty across our entire condensate pump range.
SPECIALISED INNOVATION CENTRE
Our global team of over 12 highly skilled design engineers—specialising in pumping principles, electronics and sensor technologies—have earned BlueDiamond an outstanding reputation within the HVACR industry. Drawing from nearly 75 years of expertise from Charles Austen Pumps Ltd, our team continues to achieve groundbreaking industry firsts. One of our most notable innovations is the Rotary Diaphragm pumping principle, which laid the foundation for our entire condensate pump range. In recent years, we’ve miniaturised this technology into the GyRok™ pumping principle, featured in our MicroBlue series, further advancing the performance efficiency and scalability of our products.
GLOBAL DISTRIBUTION FACILITIES
BlueDiamond® pumps are available worldwide, supported by strategically located warehousing hubs in the UK, EU and USA. Our global distribution network supplies over 4,000 trade centres and a wide network of distributors. In Europe, we operate five dedicated facilities—including our newly opened site in the Netherlands, which was established in 2020 to enable faster, more accessible dispatch across the continent and to support our ongoing expansion. With the capacity to manage large-scale orders and double-shift operations in place, we ensure stock items are dispatched within 24 workday hours to meet growing global demand.
