Description

Dolphin Diamond Amp Master 3500 Pumps are the perfect choice for both freshwater ponds and saltwater reef applications. All Dolphin Amp Master Pumps are manufactured using one impeller designed to operate on each motor as close to 100% efficiency as possible. For this reason we do NOT offer the gimmick of multiple impellers or smaller impellers on the same motor running at poor efficiency rates. Flow rates on all Amp Master Pumps may be dialed back with a discharge ball valve to any desired flow rate with no harm to the pump. Amperage rate will drop as flow rate is reduced to your desired rate. The most efficient way to plum any system is to install a ball valve at the discharge union then a tee fitting plumbing a closed loop manifold with return reducing tees wherever you want a flow return. A closed loop can be any shape or design as long as both ends return to the tee at the ball valve. This ensures even pressure through your return manifold. All Dolphin Pumps have pre-filter priming pots available for installations where water is being drawn up from source or when pre filtration of debris is needed.

• Type 1 pumps are recommended for clean freshwater use.
• Type 2 pumps are recommended for freshwater use and Koi ponds where the water may be dirty.
• Type 3 & Type 4 pumps are recommended for saltwater aquariums and other saltwater applications.

• Dolphin Amp Master 3500 Pump

  The Dolphin Amp Master 3500 is a high-performance external aquarium pump designed for reliable, efficient water circulation in aquariums, reef systems, ponds, aquaculture systems, and other aquatic applications. With a maximum flow rate of 3,500 GPH, the Amp Master 3500 provides substantial water movement while maintaining quiet, cool-running operation.

  Ideal Applications

  The Dolphin Amp Master 3500 is an excellent choice for:

  • Reef aquariums
  • Saltwater aquariums
  • Freshwater aquariums
  • Aquarium sump return systems
  • Aquarium filtration systems
  • Coral propagation systems
  • Fish holding systems

  Excellent Choice for Reef Aquariums

  The Dolphin Amp Master 3500 aquarium pump provides the dependable water circulation required by many medium and large aquarium filtration systems. Its external configuration keeps the motor outside the aquarium, while its efficient design provides strong circulation for sump returns, filtration equipment, closed-loop systems, and other water-processing applications.

  For reef aquarium owners, freshwater hobbyists, aquaculture professionals, aquarium stores, and commercial installations, the Amp Master 3500 offers an efficient solution when reliable water flow and continuous operation are important.

  Freshwater & Saltwater Pump Options

  The Dolphin Amp Master 3500 can be equipped with seal configurations designed for different water conditions. Dolphin recommends its specialized saltwater seal for marine aquariums, reef systems, mineral-rich water, and systems using harsh or abrasive additives. The saltwater seal uses AISI 316 stainless steel and hardened seal faces to provide increased resistance to corrosion and abrasion.

  For freshwater aquariums, ponds, and other compatible applications, the freshwater seal configuration provides reliable long-term performance.

  High-Flow External Aquarium Pump

  If you are looking for a 3,500 GPH aquarium pump, external reef tank pump, aquarium return pump, high-volume aquarium pump, or aquaculture water pump, the Dolphin Amp Master 3500 is engineered to deliver dependable circulation while providing the advantages of an external pump design.

  Its combination of high flow capacity, low power consumption, quiet operation, durable construction, and continuous-duty performance makes the Dolphin Amp Master 3500 an excellent choice for aquarium and water-circulation systems.
