Aquascape Ext 12000 3-p Pond Pump
AQ-45051
Three-Phase External Pumping for High-Volume Commercial Pond Systems
The Aquascape Ext 12000 3-P is a three-phase external pond pump rated at 12,500 GPH (47,319 LPH), delivering the same high-volume output as the single-phase Ext 12000 but designed for sites with three-phase power supply such as commercial properties, farms, and industrial facilities. Three-phase operation provides smoother, more efficient motor performance and is preferred where continuous high-duty-cycle pumping is required.
Industrial-Grade High-Volume Pumping for Demanding Sites
Three-phase power allows the Ext 12000 3-P motor to run at higher efficiency with less vibration and heat than a single-phase motor of equivalent output, extending bearing and seal life in continuous operation. Commercial water feature installations, large koi collections, and aquaculture operations that have access to three-phase power benefit significantly from the reduced operating cost and extended service life of three-phase motor designs at this output level.

How to Use
Install the Ext 12000 3-P on a stable, level surface adjacent to the pond or water feature. Ensure the pump is primed before first start-up; connect the inlet plumbing to the pond or sump intake at a level that maintains a positive suction head. Connect the discharge to 5 cm (2 in) plumbing routed to the waterfall, filter, or distribution manifold. Electrically connect the motor to the three-phase supply through a suitable motor starter with thermal overload protection. The oil-free, fan-cooled TEFC motor requires no lubrication but should be inspected annually. Change the mechanical seal oil according to the service schedule in the pump manual.
Ideal for commercial koi ponds, large professional water features, and aquaculture recirculation systems at sites with three-phase power supply requiring up to 12,500 GPH (47,000 LPH) at heads up to 6.4 m (21 ft).
