Straight Line Sumo Max Flow Pump Features

  • 4,250 Gallons Per Hour: The Super Max Flow Pump can fill over 200 pounds in 60 seconds!
  • Plug-N-Play Operation: Designed to work with all Sumo, Straight Line and Big Bag models.
  • Sumo Dry-Lock Link Valve: Creates a water-tight seal for leak free operation and a dry boat.
  • Sumo Switch with LED Lighting: Stop wondering whether or not your portable pump is working.
  • Fully sealed motor with dual rubber gaskets: Helps to give ballast pump a longer life.
  • Clear View 12 Foot / 3.5 meter long armored hose: Be able to see the flow while filling/draining.
  • 12 Foot / 3.5 Meter long power cord: Be able to reach a ballast bag in any spot of your boat.
  • 1-1/2 Inch / 45mm water intake port: Larger diameter = quicker fill/drain times.
  • Fully submersible: Works with both freshwater and saltwater.

Bag Compatibility: This ballast pump is only compatible with Straight Line Sumo and Straight Line Big Bag ballast bags equipped with the LINK fitting. A gasket kit is supplied with the MAX pump to be cross compatible with these two series of Straight Line bags. But some residual water may leak out during the filling and draining process. 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 about this.

* We are aware of a discrepancy between the rated volume and the rated weight this pump can produce. We are providing the numbers published by Straight Line for consistency. Based on our testing, the 200 pounds/minute fill rate is an accurate real world number.

Open Box Item: This is a brand new item, but is considered to be an "open box" item due to not having the original retail packaging.
