The Dolphin Diamond Amp Master 4750 delivers strong, consistent water flow for saltwater aquariums and aquaculture systems. 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 saltwater-specific high-performance seal uses high-grade stainless steel AISI 316 and harder seal faces to resist corrosion and abrasion, providing extra years of reliable service in harsh marine environments.
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.
