Description

The Aquascape Ultra 1500 Water Pump (SKU 91009) is a mag-drive submersible pump rated at 1,480 GPH maximum flow with a 16.5-foot maximum head, drawing just 153 watts on a 25-foot cord. The Ultra 1500 is the mid-range model of Aquascape’s five-pump Ultra series, positioned between the 1100 and 2000 for medium ponds, waterfalls, external filters, and decorative fountain features requiring steady high-volume circulation at modest operating depth.

Every Ultra 1500 ships as a complete installation kit: the included 3-way diverter valve splits flow between a waterfall return and a fountain display simultaneously, the threaded elbow routes the discharge, and multi-size hose fittings connect to 3/4”, 1”, or 1.25” tubing without additional parts. The locking pre-filter cage protects the impeller and releases tool-free for cleaning. Backed by a 3-year warranty.

1,480 GPH Max 16.5 ft Max Head 153W Mag-Drive 25 ft Cord 3-Way Valve Included Submersible 3-Year Warranty
⚠ Installation note: The Aquascape Ultra 1500 is a submersible-only pump — it must remain submerged in water during operation and is not rated for external (dry) inline installation. Not approved for swimming pools, saltwater, or water containing corrosive chemicals. A GFCI-protected outlet is required.

Key Features & Benefits

🧲
Mag-Drive Motor — Efficient & Seal-Free
Aquascape’s magnetic-drive design couples the impeller to the motor via opposing magnets, eliminating the mechanical shaft seal that is the primary failure point in direct-drive pumps. The oil-free design is completely fish-safe from the moment of first startup — no break-in period, no contamination risk. At 153W for 1,480 GPH, the Ultra 1500 delivers approximately 9.7 GPH per watt.
🔀
Included 3-Way Diverter Valve
The included 3-way diverter valve allows you to split pump output between two destinations simultaneously — a primary waterfall return and a secondary fountain or water feature display. Each output adjusts independently to dial in exact sound and visual effect. Close one port fully to direct all 1,480 GPH to a single destination for maximum waterfall output.
🔒
Locking Pre-Filter Cage
The locking cage prevents accidental dislodgement during pump handling and releases with a simple twist for cleaning. The foam filter pad inside protects the impeller from fine particles — one of the most common causes of early mag-drive pump failure, especially sand and fine gravel common in natural pond substrates.
🌊
16.5 ft Maximum Head
The 1500’s 16.5 ft maximum head handles typical residential waterfall heights with confidence. Note: the Ultra 1500 actually has a slightly lower max head than the Ultra 1100 (17 ft) because it is optimized for high volume flow at low-to-moderate head rather than maximum head pressure — an important consideration for very tall waterfall installations.
📐
Wide Flat Base with Rubber Feet
The 9.5”×6” base keeps the pump stable on any flat pond bottom surface. Four rubber feet absorb motor vibration to prevent the low humming sound that narrower-based pumps can transmit through fountain basins and hard pond floors — important for ponds near seating areas or bedroom windows.
🏆
3-Year Warranty
The Ultra 1500 is backed by Aquascape’s 3-year limited warranty covering manufacturing defects from date of purchase. The warranty requires the pump to be operated fully submerged in freshwater only — operating it dry or in saltwater/chlorinated water voids the warranty and permanently damages the motor.

Note on head heights: The Ultra 1500 (16.5 ft) has a slightly lower max head than the Ultra 1100 (17 ft) because it is optimized for higher volume flow at moderate head, not maximum head pressure. If your waterfall exceeds 15 ft, consider the Ultra 2000 (20 ft max head). All Ultra pumps are submersible mag-drive with 3-year warranty.

Frequently Asked Questions

What are the primary applications for the Aquascape Ultra 1500?

The Aquascape Ultra 1500 (SKU 91009) is a submersible mag-drive pump ideal for:

  • Medium pond circulation — 1,480 GPH max flow for ponds up to approximately 1,500 gallons
  • Waterfalls and streams — 16.5-foot max head handles standard residential waterfall heights
  • External pond filters — reliable steady flow for pressurized and gravity-fed external filters
  • Split waterfall + fountain — the included 3-way valve routes flow simultaneously to a waterfall and a decorative display

The Ultra 1500 is submersible-only and is not rated for external or dry-installation use.

How does Mag-Drive technology benefit my pond?

Mag-drive (magnetic-drive) technology couples the impeller to the motor using magnets rather than a direct shaft. Key advantages for pond owners:

  • 100% oil-free — no shaft seals or oil that could contaminate pond water; completely safe for koi, goldfish, and aquatic plants
  • Longer service life — shaft seal wear is the primary failure mode of direct-drive pumps; the mag-drive design eliminates this failure point entirely
  • Energy efficiency — at 153 watts for 1,480 GPH, the Ultra 1500 delivers approximately 9.7 GPH per watt
  • Quiet operation — no mechanical shaft connection means no shaft vibration transmitted to plumbing or pond structure
Is the Ultra 1500 Water Pump easy to maintain?

Yes. The locking pre-filter cage releases with a simple twist to expose the foam filter pad and impeller housing. To maintain:

  • Twist off the locking cage and rinse the foam pad in pond water (not tap water, to protect beneficial bacteria)
  • Remove the impeller housing and clean the impeller and shaft with a soft brush and mild white vinegar to dissolve mineral scale
  • Rinse and reassemble before returning to operation

The foam pad protects the impeller from fine debris including sand — the leading cause of reduced flow over time in mag-drive pumps operating in natural ponds with gravel substrates.

What size tubing is compatible with this pump?

The Ultra 1500 includes multi-hose fittings compatible with 3/4”, 1”, and 1.25” tubing (flexible PVC or kink-free). Aquascape also confirms compatibility with 1.5” pipe via the secondary fitting included with the pump. For maximum flow efficiency at 1,480 GPH, use the largest practical pipe diameter (1.25” or larger) with minimal bends and elbows on the discharge side.

Can I adjust the water flow on this pump?

Yes. The included 3-way diverter valve splits and adjusts flow between two outputs. Close one port completely to direct all flow to a single destination for maximum waterfall volume, or balance between a waterfall and a fountain display. For total flow reduction, an inline ball valve (sold separately) can be added to the discharge run — note that restricting a mag-drive pump’s output valve fully for extended periods increases back-pressure on the impeller assembly.
