The Dolphin Diamond Amp Master 4750 delivers strong, consistent water flow for freshwater aquariums and ponds. Designed to operate without the common drawbacks of magnetic drive pumps, it runs quietly, stays cool, and uses less energy while minimizing heat transfer. Its freshwater-specific high-performance seal is engineered to last significantly longer than standard carbon-faced seals, ensuring years of dependable use.

Each pump features a precision-molded wet end, a custom-designed impeller for maximum efficiency, and high-grade polymers that resist UV damage, moisture absorption, and abrasion. Perfect for larger systems, the Amp Master 4750 includes 1.5" super seal solid unions and an anti-vibration pump pad for easy installation and stable performance.
