We design and manufacture well service and well intervention pumps for hazardous area environment operation. Our pump packages achieve your application-specific flow and pressure requirements and meet the hazardous area standards and specifications of your operating region including NORSOK, ATEX, and IECEx. These pump units all benefit from Calder’s wealth of offshore, hazardous area design and engineering experience which has made our products popular and trusted with offshore energy operators for over three decades.

Post completion, there are many well service applications requiring a large range of pressures, flows and pumped medium. With maintenance and well integrity critical, our in-house design and engineering team focuses on safety and reliability to ensure our products meet the high expectations of our customers.

Our range of products covers all pumping applications for well intervention work towards the end of the life of a well. Our combination of standard products, bespoke engineering capabilities, and product quality ensure we have the solution to your well intervention pumping requirements.
