This replacement seal kit is designed to restore optimal performance to Dolphin Pumps by replacing worn or damaged internal seals that can lead to leaks and reduced efficiency. Available in specific versions for either freshwater or saltwater pump models, each kit contains the precise components necessary to reseal the wet end of the pump and prevent water intrusion into the motor housing. Proper installation ensures the longevity of your circulation equipment and maintains a safe, dry environment for your aquarium electronics.

The kits are compatible with Dolphin Pump model numbers 3500, 4750, 6250, 7450, 9250, 10500, and 15500. It is critical to select the correct version based on your pump's original configuration, as there are distinct kits manufactured specifically for freshwater versions and others exclusively for saltwater versions. Using the incorrect kit can result in premature failure or leakage due to differences in material compatibility with fresh versus saline water environments.

This product is best suited for reef aquarium hobbyists and technical staff who own Dolphin Pumps and need a cost-effective solution to extend the service life of their circulation equipment rather than replacing the entire unit. Whether maintaining a large display tank or a complex sump system, this seal kit provides an essential maintenance component that ensures reliable water flow and prevents potentially catastrophic pump failures in saltwater systems.
