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

**This pump ships from Dolphin Corp. in Florida, USA**

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.
