The Neptune PMUP V2 is a compact and versatile utility pump designed to handle a wide range of tasks in both saltwater and freshwater aquariums. Its primary function is to reliably move water for auxiliary equipment, making it an essential tool for automated top-off (ATO) systems, media reactors, or any other application requiring a small, dependable pump. This pump is engineered to integrate seamlessly into complex aquarium systems, providing consistent flow for critical life support functions.

The second version of the PMUP introduces significant upgrades for enhanced safety and convenience. It now features an automatic shut-off function that protects the pump from damage by turning it off if it runs dry, along with over-temperature protection to prevent overheating. A newly designed removable screen allows the pump to stand upright, simplifying placement and installation in tight sump spaces. These improvements also make the pump easier to disassemble for routine cleaning and maintenance, ensuring long-term performance.

This multi-purpose pump is ideal for the aquarist who values reliability, safety, and versatility in their equipment. It is particularly well-suited for reefkeepers running GFO, carbon, or biopellet reactors that require a steady, low-flow water supply. Hobbyists looking for a trustworthy pump for their auto-top-off reservoir will also appreciate the new safety features that prevent pump burnout and potential system failures, offering valuable peace of mind.
