Description
Product Overview
The Danner Supreme Mag Drive Impeller Cover is engineered to restore the performance of your aquarium water pump quickly and reliably. Constructed from high‑impact polymer, the cover resists corrosion and cracking, even in the demanding environment of a continuously running pump. It includes a precision‑molded rubber seal ring that creates a watertight barrier, preventing leaks and protecting the motor. Dimensions of 5.3 x 3.1 x 0.3 inches ensure a perfect fit for model 12535 and compatible Pondmaster units. The lightweight design (0.16 ounces) makes handling and installation effortless, while the robust threading guarantees a secure connection without over‑tightening.
Usage
Designed for both home aquarium enthusiasts and commercial pond operators, this impeller cover fits seamlessly into existing pump assemblies. Whether you are maintaining a freshwater tropical tank, a reef system, or a decorative garden pond, the cover helps maintain consistent water flow and reduces the risk of pump failure. Installation requires only a screwdriver and a few minutes—simply remove the old cover, place the new rubber seal, align the threads, and tighten to hand‑tight.
