Range replacements

Watson-Marlow operates a policy of continuous product improvement. As new models are introduced, old models are phased out. This guide makes clear which models have been discontinued, and what is the recommended replacement.

The following list refers only to drives. The pumphead shown should not be considered. The pumps pictured are representative and not necessarily a specific model.
