Snyder Industries’ unique molded drain fitting, the SUMO™, has been developed from knowledge accumulated from over 50 years of rotationally molding polyethylene tanks. The SUMOT” was designed to help ensure maximum liquid drainage from vertical bulk storage tanks.

Maximum Drainage:
Using standard bulkhead fittings as outlets for vertical storage tanks can leave as much as 9″ of liquid in the bottom of the tank. This means the tank is keeping your product, and your money. The SUMO™ provides maximum drainage so the product gets to your customer. It also helps reduce unscheduled maintenance downtime due to build up of sediment.

Ease of Installation:
Because SUMO™ is molded into the tank, pipe and fitting assembly is also easier with no secondary siphon tube assembly required.

The Sumo’s™ encapsulated insert allows for modification free attachment to two, three, four, and six inch ANSI pipe sizes, and can be located at 90° locations around the base of most of our tanks.

Snyder is able to encapsulate either a stainless steel, hastelloy, or titanium insert into the wall of the tank. This encapsulated insert is then sealed off from the liquid contents of the tank by the two O-rings that are installed on a specially machined male adapter.

The SUMO™ provides a metal reinforcement completely isolated from any chemical attack.

Maximum tank drainage results from the SUMO™ being molded at the knuckle radius of the tank.

Longer Tank Life:
With other polyethylene tank “full drainage” outlets, additional flange connections are required. With the SUMO™ you eliminate this cost by piping directly into it. A molded-in outlet also reduces the stress on the tank caused by cutting and bolting. This means you’ll save even more money since your tank will last longer. More importantly, you avoid having resin that is not fully cured in the area of the tank that is most stressed. And, if the SUMOT” fitting is damaged for any reason, it can be repaired. This further extends your tank life.
