As OASE have continued to evolve and develop their brand through the years, their foundational lines of outstanding German-engineered pumps have also seen generational upgrades.

Since bringing the already established German brand to the UK in 1993, advancements in technology have worked to continuously reduce pumping energy consumption without ever compromising on quality or performance. The most recent OASE Core-6 winding technology has once again set a new industry benchmark for Eco pond pumps.
With each new generation of OASE pump, the bar is raised!
So reliable are OASE pumps, that many of the original generation pumps are still installed and operational today, despite not having been manufactured this century! This unrivalled reliability keeps consumers returning to the brand for their pond, water feature and fountain pumping needs, often wishing to replace their pump like-for-like when an OASE pump does eventually expire. However, with OASE pumps remaining in service for so long, it can be a challenge to identify a modern replacement when the time does come, as the original pump may be numerous generations back in the timeline, long since superseded with new and improved models.
This article aims to direct satisfied OASE pump owners looking to replace an old, expired OASE pump to the current OASE equivalent pump from the superb range of OASE pumps being manufactured today.

OASE PondJet Floating Fountain Pumps
Variants of the OASE PondJet Floating Fountain have been in existence for many years. While the product itself remains largely unchanged from the original design through to the current product, the pump that powers this elegant fountain has undergone redevelopment a number of times. The below chart documents the pump supplied with the PondJet Floating Fountain through the years. OASE have always made it so that the new generation of pump should retrofit where the older generation of pump used to fit. The PondJet pumps are supplied as "service packs" with adapters and brackets to ensure that a newer generation pump can always be installed onto an original fountain.
