Use this chart to determine the proper size pump for your pond. The height of the water outlet above the surface of the pond is called the Head Height. Gallons Per Hour (GPH) represents the maximum amount of water your pump is capable of pushing at a given Head Height. To ensure the pump's best possible performance, reduce frictional losses by using the largest diameter hose possible.

Pondmaster Statuary Pump w/ Built-in Flow Control, 190 gph

Pondmaster magnetic drive pumps are specifically designed to meet the demands of a pond. Unlike most other pumps on the market, magnetic drive pumps are made to run continuously, without seals to wear out. Magnetic drive pumps are highly energy efficient using less energy than direct driven pumps, and they will potentially save hundreds of dollars over time. Filled with epoxy, rather than oil, these pumps cannot leak oil into the pond, which can be harmful or fatal to fish and plants. Pondmaster's magnetic drive pumps are low-maintenance with only one moving part, a ceramic shaft and impeller. The pumps also feature an ABS case, corrosion-proof fasteners, and heavy duty copper windings, resulting in a durable, energy-efficient, and long lasting pump. All Pondmaster pumps are suitable for statuary, fountains, and ponds.

This Pondmaster Statuary Pump is perfect for small to medium size garden fountains, piped statuary, and ponds. Its unique design gives this pump unmatched versatility. Submerge this pump horizontally or stand it vertically to operate in as little as 1/2" of water. The built-in adjustable flow control allows you to determine the output with the turn of a dial. The included washable foam pre-filter keeps the pump running smoothly. This submersible pump will run quietly and faithfully while operating your water feature. The pump is equipped with a 1/4" threaded outlet and includes an elbow for 3/8" or 1/2" ID vinyl tubing. Three year limited warranty.
