pump for a water feature

Which pump for a water feature?

Pump for a water feature, or existing fountain? read this.

A pump for a water feature, or fountain. be it old or new we can help, it is usually not a problem, provided we are given all the information required. i.e. diameter of outlets, quantity of outlets, required jet height etc

A genuine enquiry is as follows:

Can you please advise me on the type and cost of a pump for a fountain that consists of a 1.5M ring with 22 x 5mm nozzles on it. From your web page I assume they are komet nozzles. The ring is 2" pipe with a short piece of 11/2" pipe to a valve. My client requires the fountain to have a head of 2.5M.
Many thanks.

Budget: 200-299

This enquiry is very good since with out asking we have been given all the information we need.

For your reference:

These are two komet 3-5T nozzles, (As the enquirer correctly mentions)

Each has an orifice of 5mm

The only "problem" is that of water demand, or lack of understanding of it. As the enquirer says, "The spray ring has 22 outlets" each outlet is 5mm in diameter. The "average" domestic pump when used with a komet 3-5T (see above picture) will reach around 100 cm, possibly 150 cm in height, but, as mentioned by the enquirer, this spray ring has 22 individual 5mm outlets, so a domestic pump will not achieve any where near the required height, it will only be capable of around 5-8 cm in height on each nozzle, (There are 22 outlets) nowhere near the required 250 cm. The only pump we could supply that meets the required water demand for 22 x 5mm outlets is way over the budget of £299

This is a 2m diameter ring we supplied. It has 56 2.5mm outlet nozzles, to achieve a jet height of 2 metres (as shown in the picture) it uses 2 of our big pumps, via 2 inlets

Yes, 1 pump could only make all jets 1 metre high.

Another example

Another enquiry we had was for a replacement pump for this dandelion feature, these do have a very high water demand, the "give away" is that the supply pipe (green pipe on the left) is 2 inches in diameter, a "normal pump" only requires a 1 inch pipe at best. A replacement pump was considerably more than expected. (several £k)

We also supply dandelion features, which are on the components website (See the nozzles section)

As far as we can tell, in both the above cases the potential client was offered the fountain for "next to nothing" (We don't blame any one for that.) But please check with us first as to how much a replacement pump will cost as it will probably be more than you think, the cost of replacement pumps is often the reason the fountain is no longer used, and so are given away.

We also had any enquiry from a person who wanted a new pump for an existing fountain, The existing pump had given up after 15 months use, it turned out to be a sump pump, sump pumps are not designed to run for long times, we suggested a suitable pump which used less electricity (saves money) is slightly more powerful, he never brought one because as in his opinion "it costs too much" as far as we know he brought another sump pump. A pump from us would have out lasted his sump pump by YEARS and even though it costs more initially, he would also save on his running costs, and not have to keep buying a new pump every 15 months. No helping some folk.
