Half Off Ponds Manta Series MA-4100 - 4,100 GPH Waterfall Pump
Half Off Ponds Manta Series MA-4100 - 4,100 GPH Waterfall Pump
The unique design of the Half Off Ponds Manta magnetic drive series makes it an ideal choice for fountains, waterfalls and smaller ponds.
An energy efficient electromagnet is sealed in an epoxy-filled housing.
The drive shaft and electromagnetic rotor are recessed in the motor housing.
The result? Near silent operation and extremely low operating cost.
These pumps are ideal for cleanouts and drainage due to their low suction point.
The upright design with space-saving footprint makes this pump ideal for skimmer and pondless waterfall installations.
Intake screen prevents clogging while passing solids up to .
25 inch.
Asynchronous drive motor can be controlled with variable speed controller (not included) that permits you to increase or decrease pump flow as needed.
Vortex impeller passes solids to .
25.
Engineered for 24-hour continuous use; overload sensor prevents burnout.
Contains no oil; completely safe for fish, wildlife and aquatic plants.
2-year manufacturer's warranty.

FAQs & Calculations to Help Select the Correct Kit
1. 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
2. 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:
Water Garden, Few Small Goldfish
Circulate total pond water valoume every 2 hours.
Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.
Fish Pond, Several Small Fish
Circulate total pond water valoume every 1 hour.
Example: 3,800 GPH pump for a 3000-gallon pond with 2’ waterfall.
Koi Pond, Several Large Fish
Circulate total pond water valoume every 3/4 hours.
Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.
Calculating Head Height
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.
