The Diamond Series pump is the world's greenest pump.
With these improvements, the 1.5 Fringe Tech Wet End draws lower amps and attains higher head pressures and flow rates than any of our previous generation 2 Amp Master pumps, especially when plumbed to 2 manifolds. The performance improvements combined with the new seal technology make the Fringe Tech 1.5 compact Amp Master a pump that has no equal, more so when plumbed to 2 pipe.
Why Green? The Diamond series offers the highest flow and head pressure per amp. Theses pumps are cool and quiet running for indoor or unprotected outdoor use.
Important Pump Information
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 where ever you want a flow return. A closed loop can be any shape or design as long a both ends return to the tee at the ball valve. This insures even pressure throughout your return manifold.

Fringe tech 1 - fresh tempered
Fringe tech 2 - clean marine seawater
