DOLPHIN PUMPS

PERFECT FOR AQUAPONIC AND HYDROPONIC FARMS

ABOUT OUR SEALS

Dolphin Pumps are designed and manufactured for maximum efficiency and minimum power consumption, allowing for cost-effective and worry-free operation of your aquaponic or hydroponic system.


Fringe Tech Seals:

The fringe tech seal is available in a choice of four types to meet the requirements of almost all applications. The engineering design is the same for all 4 types available the difference is in the metals polymers and seal surfaces used. Therefore the Diamond series  pumps can easily pump pure to very abrasive fresh and salt waters. Type 1 freshwater seal will last years longer than other freshwater seals through design  and the use of much harder surfaces found in standard freshwater seals.


Type 1 Freshwater seal

Over double the work life expectancy of other style freshwater seals.  10-year factory service guarantee.


Type 2 Marine

Designed for pumping clean non-abrasive marine water. 10-year factory service guarantee.


Type 3 Marine reef & other corrosive water

Designed for pumping water containing abrasive sand and minerals.  A seal designed to outlast the motor.


Type 4 Fresh, marine and any abrasive water

With lifetime factory service guarantee. The leader in seal technology.  A non-fail, lifetime seal. Offers all the advantages of seal-less options without all the disadvantages. True diamond seal is super slippery, minimal friction and energy consumption. Recommended for extreme abrasive environments and where the pump will cycle on and off.

DOLPHIN AMP MASTER 4750 & 6250 MODEL AND PRICE

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 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.
