OASE has a pump for virtually every application.

Before you just choose any pump consider how you are going to use the pump. Will it need a lot of flow, but not much pressure, a lot of pressure and not much flow? Taking these factors into consideration before you buy a pump, will ultimately save you time and money! The vast array of products available can make the design aspect of a water feature challenging.

Fountains: First you need to decide what type of spay pattern you are going to have in your pond? Then you determine how high and wide your water will spray. Keep in mind that water has the ability to splash the distance that it falls, up to about eight feet. Once you have made this determination the nozzles will recommend a pump that will achieve your goals, based on flow rate and head pressure.

Waterfalls: Waterfall and watercourses are a popular feature of any pond installation, but the flow required for a successful display is an important consideration. Waterfalls & watercourses come in two basic types, the first being a clean edged weir free from obstructions, and the second being a weir with embedded rocks and similar watercourse. The rocky weir and watercourse requires less water flow than the clean edge weir does.

These figures should prove useful when selecting a pump for your waterfall. First, determine how wide the waterfall will be and what configuration. Determine your waterfall width, multiply it by the amount of GPM required as by type of waterfall. Then determine the height of the waterfall, from the lower pool to the upper pool (head pressure). Check the pump curve on the model of pump that you are considering.

• Rocky edge type: a flow of 1/8" -1/4" water rise is usually sufficient (4-9 gpm per linear foot ).
• Clean edge type: a minimum of 1/2" of water over the weir ( 20 gpm per linear foot ).
