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.
SpecificationsStraight Line Sumo Max Flow Pump Features
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.This pump literally is a game changer. I have 2 850 pound and one 450 LbS sumo bags and with the kids I would have to choose surf days wisely because it took so much time to prep and empty. I can fill all 3 bags in 15 min now and empty in 20 min. Used to take me 30 min. Now I am able to surf more 👍👍
This is my 2nd pump in 4 years. The first one had great flow volume and filled my 850 Sumo in a short amount of time. The only down side was the flimsy hose that comes with the pump. My hose tore repeatedly when new and and I kept cutting and re-clamping the hose back on to the pump to extend it use. I am very careful with my equipment, the hose was just lame. I ended up replacing the original hose with a piece of flexible PVC hose until the pump died. It’s a sealed unit so I had no way of diagnosing the cause of failure. I thought it should of lasted longer for the money and limited use. My replacement pump is the exact same pump and hose construction. I partly zip tied the electrical cable to the hose to try and strain relieve the hose with the cable. I guess I will see how long this one lasts.
Quality not great. The hose split right where it is connected to the pump causing water to shoot everywhere and basically making the pump useless. Only used pump 5 or 6 times. Very disappointed. It worked great until the hose split
The Sumo Max pump is a great pump, very fast and robust, the hose and the connection on the hose are a bit iffy, have had the hose and pump for about two months, the hose is already broken in two places. The end connector that connects to the bag broke the first outing. After Wakemakers didn't have a replacement available for it and the manufacturer would never return a call or email, we fixed it ourselves. It could be a fabulous system with a more robust connector and a better hose.
The most significant positive first - the fill rate on this is fast. I throw the pump over, and it quickly fills my 1000 lb sack in 5 minutes. We're always in a hurry to start, so that's great. And the long hose and cord are nice too. Negatives though are severe. You'll only get that flow rate for the pump submerged in water so filling. When emptying, you're relying on a little pressure from the sack forcing water into the pump and low suction. At best, it takes twice as long to empty and many days, closer to 3 times. When you're done surfing at the end of the day, 10-15 minutes to empty a 1000 lb bag feels like forever. The pump inlet is also fragile. There's a small piece of plastic that serves two roles. First, it locks the pump into the bag fixture. Second, it depresses a valve in the bag to let water in and out. Unfortunately, that flimsy plastic is easy to break when doing the "press down and turn" to lock the pump to the bag. With that broken, you can't depress the valve to open or shut. When mine broke, I was able to drill it and put a small bolt through to be the lock and valve depressor. Like all boat accessories, get used to the idea that this pump is disposable and will need to be replaced every few years.
