Ejector system vs. Vacuumarator™ pump unit

Ejector system vs. Vacuumarator™ pump

The compact Jets™ system has unmatched benefits compared to other sanitary systems and solutions available for ships. Although the ejector system introduced in the seventies was a recognized principle in its day, the Vacuumarator™ pump launched by Jets™ a decade later was a breakthrough in modern vacuum technology.

Eliminates foaming problems

The Vacuumarator™ pump is easy to fit into the design and easy to install, with plug-in packages that save installation time and costs. It is easy to operate, eliminates foaming, and has no need for a circulation tank.

For all applications

The Jets™ system can feed any type of sewage treatment plant and cuts life-cycle costs for ships of all sizes. Our solution has proved particularly useful in cruise ships and ferries where system loads are continuously high.


A direct comparison for shipowners, designers and builders

This table makes a direct comparison between the characteristics of the older ejector system and our own Vacuumarator™ pump.

The comparison speaks for itself, but allow us to point out that the numbers presented are for a single unit.

In ships with multiple units, the benefits and advantages of a Jets™ system with Vacuumarator™ pumps can also be multiplied when comparing.
