The Yamitsu range of Wattpumps were custom designed for use on garden ponds, water features, waterfalls and koi ponds. They are built to deliver large volumes of water at very low electrical consumptions whilst maintaining high pressure levels. This is a fundamental requirement for a good filtration system. Their highly efficient design ensures high performance with very low running costs.
These pumps come complete with large strainer baskets for easy maintenance and helps assist the pump in priming which also dramatically helps with the pumps economical running costs.
To choose the correct pump for your system there is a simple rule of thumb. Take the volume (gallonage) of water in your pond and divide this figure by 2. For example a 1000 gallon pond needs a pump that is going to pump 500 gallons per hour (the entire contents of your pond every 2 hours) after all allowances have been made for frictional losses that will be encountered in your pipework. Using the figures quoted by some pump manufacturers, you would probably need to consider an 800-1000 gallon an hour pump!
Pumps are always under pressure. It is as if they are always pumping water uphill even when they are not. This resistance to flow is referred to as head. A reasonable length of pipe with some bends will reduce a pump's output because of the friction between the pipe walls and the water and the tightness of the angle of any bends and other restrictions. Fountains etc
It follows that the larger the pipe the less resistance and greater achievable water flow. Conversely the smaller the pipe the lower the possible head and reduced flow. It should be noted that a lot of pumps do not have enough power to overcome a 5 metre head.
