Dolphin Diamond Amp Master 4750 Pump - 4750 GPH
The Dolphin Diamond Amp Master 4750 is widely regarded as one of the most efficient and reliable external pumps in the water garden industry. Engineered for high-volume circulation with minimal power consumption, this pump delivers an impressive 4,750 GPH using only a 1/15 HP motor.
Dolphin Diamond Series pumps are unique because they utilize a single, custom-designed impeller matched specifically to the motor to achieve near 100% efficiency. This design ensures silent operation and virtually no heat transfer to the water, making it ideal for sensitive koi ponds and aquatic reef systems.
