Aqua Pulse 2,000 GPH Submersible Pump for Ponds, Water Gardens,

Aqua Pulse Series AP-550 - AP-2000 Models

How Big of a Pump Do I Need?

Minimum pump size is determined by pond type, water volume, head height and friction loss. The minimum pump size recommendations are:

Circulate total pond water volume every 2 hours.

Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.

Circulate total pond water volume every 1 hour.

Example: 3,800 GPH pump for a 3000-gallon pond with 2’ waterfall.

Circulate total pond water volume every 3/4 hours.

Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.

Dynamic head pressure is found by taking the vertical height of your waterfall; the distance between where your pump is (typically in the skimmer) and where your waterfall is, and adding the static head pressure (pipe and fittings) 1’ for every 10’ of tubing and 1’ for every elbow or “T” fitting.

Example: 3' (vertical height) + 2.5 (25' of tubing) + 2' (for 2 elbows) = 7.5' of Dynamic Head Pressure

Note: It is important to take into consideration while calculating how much flow will be at the top of your waterfall by accounting for the head height due to the laws of fluid dynamics. Please refer to the flow chart above to help choose the correct pump.

What Size Tubing Do I Need?

Half Off Ponds Flexible PVC Tubing (NOT included in this listing) is ideal for ponds and waterfalls requiring high-strength and flexible hose that resists kinking and collapsing. This tubing withstands freezing without compromising its' structural integrity, durability, or strength.Pipes, hose, and tubing are the 'circulatory system' of any Koi pond, water garden, or waterfall. Selecting the right pipe, hose, or tubing for any water feature project is a key decision to create and maintain a healthy water environment; from a residential backyard ponds to commercial water features or municipal projects.Half Off Ponds Flexible PVC Tubing is used with Schedule 40 fittings and accepts schedule 40 primer and glue for a secure fit every time.

• Can be frozen solid without losing strength or structural integrity
• Smooth wall interior improves water flow, prevents friction loss
• Flexible, will not collapse or kink around bends or curves
• Works with standard schedule 40 PVC slip or barb fittings: Fish amp; Wildlife Safe

Calculating Water Feature Size for Accurate Pump Selection

How Many Gallons of Water does My Water Feature Hold?

Rectangular Ponds

Length x Width x Average Depth x 7.48 = Gallons

Example: A rectangular pond 15’ long, 10’ wide and 1.5’ Deep Pond is... 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Oval Ponds

Length x Width x Average Depth x 0.8 x 7.48 = Gallons

Example: An oval pond 15’ long, 10’ wide and 1.5’ deep is... 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Round Ponds

Length x Width x Average Depth x 7.48 =Gallons

Example: 15’ long, 10’ wide and 1.5’ Deep Pond 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons

Streams

Length x Width x Average Depth x 0.25 x 7.48 = GALLONS =Gallons

Example: 15’ long, 10’ wide and 1.5’ Deep Pond 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
