Dolphin Amp Master Diamond External Marine Pump - 4750 GPH (Type-2)

Dolphin seals are custom designed and engineered to outperform and outlast all other pump seals on the market. Dolphin recommends type 3 abrasive proof seals for all reef and coral containing marine aquariums since these marine environments are all considered abrasive. The type 3 seals are designed to handle this environment with the reliability of a magnetic drive pump without all the drawbacks, such as heat transfer, noise, and energy consumption. All of our type 3 and diamond type 4 sealed amp master pumps include a 3-year factory warranty. For freshwater use the new fringe tech series type 2 seal design and surfaces are designed to provide a much longer service life than any other fresh water pump.

See the Dolphin web page for Installation & Warranty Information: //www.dolphinpumps.com/installation-tips-and-warranty


Description:
All Dolphin Diamond Amp Master Pumps are manufactured using one impeller custom designed to operate on each motor as close to 100% efficiency as possible. Dolphin Pumps have completely redesigned the liquid end (wet-end) with parts that are precision molded using state of the art, high tolerance equipment. The highly polished flow channel is designed to move discharge water efficiently with the lowest possible friction rate from rough surfaces and poorly guided water flow. The wet-ends incorporate a custom and unique mechanical seal design, engineered to provide a much higher service life than the seal types found in other pumps. Dolphin Diamond Series wet-ends and impellers are engineered to the highest tolerances and run on the latest generation equipment to produce the extreme specifications using only high performance plastics. All polymers selected provide:
  • Outstanding impact and crack resistance
  • Service temperature range of 4° - 230° F (-20° - 110° C) Impact strength is reduced at extreme cold temperatures
  • Unaffected by UV light
  • Low moisture absorbance
  • Ph range: 4 - 10
  • Chlorine Resistant
  • High abrasion resistance
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 plumb 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.
Extended Service Guarantee - On Type 3 or 4 seals. Diamond Amp Master Series pumps have the Dolphin lifetime extended service guarantee. All other pump models have a 10-year extended service guarantee. Dolphin Pumps are truly “Driven by products that work”, and if for any reason (even freeze damage) Dolphin will fix it for you. Under the factory extended service guarantee, the customer can send in (at their expense) their pump for any symptom of failure or loss of performance. Dolphin will disassemble the pump, clean the pump and determine the reason for failure. The customer will be required to pay (wholesale list cost) only for parts needed to restore the pump to reliable working condition. If the pump cannot be repaired, or the repair is cost prohibitive to age of pump, the customer will be offered a rebuilt or new unit at factory cost. Labor and pump test time is NOT charged. Return shipping will be an additional charge.

REVIEW
After researching the panworld, and iwakis and their noise levels, i concluded i wanted a dolphin. It took a couple days to break in but it got quieter and quieter. You can also use a ball valve to dial it back without any ill effects!

This pump replaced reefflo hammerhead that had "seized" after only 8 months of use. I have had no issues in 6 months of use on our 330 gallon system. This pump also has much less heat transfer then the hammerhead. I never needed a heater with the hammerhead due to the transfer (and was ...Read More

In line micron filters are filters with very fine openings to remove the finest suspended particles in sterile pool water, not biological systems, due to rapid plugging with bio slime. They require pumps able to run at higher pressures such as the Dolphin aqua sea models, not any amp master pump w...Read More
