Rule Automatic 800 GPH Bilge Pump 20SA

Rule offers the 800 GPH (3028 LPH) pump in a round version. This pump features many mounting variations as well as a gas resistant strainer base. Float switches are not required for these fully automatic pumps. Controlled via built-in sensors, the pump will turn on every 2.5 minutes for about 1 second to sense for water. If water is present, the pump will sense resistance and continue to run until all water is removed. Power use in the checking mode is minimal for the peace of mind that this range of pumps offer.

The pump is completely submersible and has a tough plastic body. It features back flow prevention to reduce the amount of water left over in the bilge. This reduces odor and helps keep the bilge cleaner. Hidden air vents within the body help prevent air locking in challenging plumbing situations and helps with the check valve. This model features a snap-lock strainer base which makes it easy to clean and a thermal cut-off for added protection. The threaded discharge provides easier installation and easier maintenance.
