The Marco UP1-TB Turbo Ballast is a professional-grade self-priming flexible impeller pump designed for high-demand marine ballast applications. With a maximum flow rate of 133 l/min - verified at approximately 20% above international market standards - it sets a new benchmark for filling and draining speed in its class.

The pump body is constructed from a self-lubricating technopolymer paired with a flexible EPDM impeller, a combination that delivers an exceptionally low friction coefficient, superior hydraulic efficiency, and an extended operational lifespan. This engineering choice also reduces the electrical load on the vessel's DC system, protecting batteries and adjacent electronics during prolonged ballast operations.

The fully reversible motor architecture guarantees equal flow performance in both the fill and drain direction, with no degradation in rate or efficiency during directional switching. Current draw remains constant through motor reversal - a critical advantage in vessels where ballast control shares a power bus with navigation, autopilot, or communication systems.

Manufactured in compliance with ISO 8846 and ISO 8849, the UP1-TB meets the certification requirements for use aboard both recreational and commercially operated vessels. Compatible with Marco's Plug-and-SURF quick-connect fitting system for simplified installation.
