Discover Dolphin Pumps

Dolphin Diamond Amp Master Pumps

Engineered for the most demanding environments, the Dolphin Diamond Amp Master series provides the reliability of magnetic drive pumps without the common drawbacks of excessive heat, noise, or high energy consumption. Available in 3500, 4750, and 6250 models, these pumps are backed by a 2-year factory warranty and a commitment to superior American-led design. Unlike "private label" imports, every Dolphin pump is built using premium materials and precision manufacturing to ensure long-lasting performance.

Advanced Seal Technology

Our custom-engineered seals are designed to outlast any standard seal on the market:

Marine & Reef Environments: We recommend our specialized saltwater seals for reef, mineral-rich, or chemically treated systems. These seals utilize AISI 316 stainless steel and hardened faces to resist corrosion and abrasion, adding years to the pump's lifespan.

Freshwater Systems: Even our standard freshwater seals are upgraded with superior materials that far outlast generic carbon-faced alternatives found in other pumps.

Precision Engineering

Every Amp Master pump features a custom-molded impeller and a redesigned "wet end" built with state-of-the-art, high-tolerance equipment. By pairing unique mechanical seals with high-performance plastics, we achieve nearly 100% motor efficiency and extreme durability.

High-Performance Polymer Features:

Temperature Resilient: Rated for service between 4°F and 230°F (-20°C to 110°C).

Chemical & UV Resistant: Immune to UV degradation and resistant to chlorine.

Durable Construction: High impact, crack, and abrasion resistance with low moisture absorption.

Broad pH Range: Stable performance in environments ranging from pH 4 to 10.

Note: For installations requiring suction lift or debris filtration, pre-filter priming pots are available for all models.
