When high-outlet discharge is required, we offer an optional lift pump station. Our lift pump station includes a factory-mounted pump and a level alarm.

easyRock solutions are delivered "ready to install", ensuring quick and simple installation.

They are shipped in Pack version — switching to Line version requires no additional accessories, making it easy to adapt to installation conditions.
