OASE Pump Application and Performance Guide

The vast array of products available can make the design aspect of a water feature challenging. OASE has a pump for virtually every application. Many questions arise concerning which pump to select to meet your particular needs.

Is the pump meant to operate a fountain or waterfall?

Was it designed for continuos operation?

Does it have a filter or can it pass debris?

Is it submersible or can it be installed out of the water?

Unfortunately one often observes pumps being used in water features that are totally unsuitable for this task, due to bearing technology and motor systems. Most of these pumps were developed as submersible drainage or sump pumps. They were designed to empty reservoirs, cellars and sumps, not for continuous operation. They have a very high power consumption rate and seldom last longer than 3000 operating hours. OASE builds pumps specifically for water features with 30,000 operating hours with energy efficient, cost affective, constant running capability. Use the table to compare and locate the right pump for your application. Before you just choose any pump consider how you are going to use the pump. Do I need a lot of flow, but not

much pressure? Do I need a lot of pressure and not much flow? Taking all of these factors into consideration before you buy a pump, will ultimately save you time and money!

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. ( If it falls four feet it can splash four feet etc. ) Once you have made this determination the nozzles will recommend a pump that will achieve your goals, based on flow rate ( GPM ) and head pressure.

Waterfall Pump Selection

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. For the rocky type, a flow of 1/8" to 1/4" water rise is usually sufficient ( 4 - 9 gpm per linear foot ), but the clean edge type should have a

minimum of 1/2" of water over the weir ( 20 gpm per linear foot ). These figures should prove useful when selecting a pump for your waterfall. First, determine how wide the waterfall will be and what configuration. If it's of the rocky type, figure somewhere between 4 and 9 gallons per minute. If is of the clean edge type, figure around 20 gallons per minute. Determine your waterfall width and multiply it but 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), then check the pump curve on the model of pump that you are considering.
