AP4 Ultra builds upon the established AutoPump system, which has been the industry leader for over 30 years. Low-maintenance pump lasts up to 10 times longer between service events and requires 50% less time to clean.

The AP4 Ultra uses proprietary non-stick finishes on the float and discharge tube to reduce solids buildup, extending the time between cleaning and making it much faster and easier to clean the pump. All metallic parts are 316-grade Stainless Steel, which has greater corrosion resistance and can withstand the attacks of the harshest leachate. The AP4 Ultra’s redesigned air control mechanism uses no fasteners or cotter pins for easier disassembly and greater reliability.
