Calder Limited designs and manufactures pump systems, specialising in high pressure and hazardous area applications. 

We are a team of more than 50 people based at our factory in Worcester, United Kingdom. We continue to design, manufacture, build and test pumping equipment as we have for over 40 years. It is important to us that Calder today is a forward-looking company that continues to innovate and evolve. However, maintaining the qualities that have made us successful over the last 40 years is of equal importance. 

Our focus is on minimising your life cycle cost by producing machines which are reliable, low maintenance, and durable. We achieve this through extensive engineering design experience, careful component selection, controlled build processes, and thorough in-house testing. In addition to a range of standard pump, vacuum and compressor units, many of our projects are bespoke. Design has to take into account a vast range of factors. For example, operating location, application, accessibility, are important considerations. Additionally, fluid type, fluid temperature, and flow and pressure requirements can be unique.
