Meet the fastest filling portable ballast system in the industry. Straight Line’s new Max Flow Pump packs 4,250GPH of ballast filling punch. Now you can spend less time filling and draining ballast and more time riding your bigger and better wave!

The proprietary design of the Straight Line Sumo Max Flow Pump is built to integrate directly with the Straight Line Sumo Max ballast bags. A larger Max Flow Link Valve makes it possible to get 50% faster fill and drain times compared to the Super Sumo Pump.

NOTE: This ballast pump is only compatible with Straight Line Sumo and Straight Line Big Bag ballast bags equipped with the LINK fitting. For maximum performance you will need to upgrade to new Sumo Max ballast bags that are equipped with the Sumo Max LINK valve. Contact us if you have any questions.
