Why You save Money by Buying 2 Pond Pumps
Profit More From Selling 2 Pumps Instead Of One and Still Make Your Customer Very Happy. This was an article I wrote to persuade hardware retailers to help customers make good buying decisions in terms of ponds and pumps. To succeed into the future everybody will have to be smarter, more flexible, and innovative. This brings me to the real subject of this article.
2 Pumps Cheaper Than 1 For Most Fish Ponds
When a consumer has a fish pond that same consumer normally has a waterfall and must also have a biofilter to ensure the fish and the pond stay healthy fish in ponds with no biofilter quickly become sick and die. Biofilters must run continuously. Waterfalls can run intermittently.
Cost saving from 2 pumps.
1. A biofilter normally requires a flow of water lower than the waterfall does so a larger pump is bought to ensure the waterfall is spectacular.
2. Larger pumps especially those that pump to a height consume a lot more electricity than smaller pumps running under low head conditions.
3. Electricity are about 30 c per kWhr and increasing.
Consider the following .
A) First pump .waterfall pump consumes 250 watts
B) Second pump .. biofilter pump consumes only 41 watts (pump capable of delivering 2500 lph)
If larger pump was used for both jobs then it would run 24 hrs per day and annual power cost would be 250/1000 * 24 * 365*0.3 = R657 per year. Over 3 years this would come to R1,971 and if pump price was R1,000 then total 3 yr cost would be R2,971
If smaller pump was bought to run biofilter and larger pump was only run for a total of 24 hours per week (just at weekend for example) . then total annual electricity cost would be R201 with both pumps running as described R107 for large pump and R94 for small pump. Over 3 years total power cost would be R603 but of course 2 pumps would have been bought. One cost R1,000 and the smaller one about R750. So total 3 yr cost would be R(1,750 + 603) = R2,353.
So 2 pumps are cheaper than 1 pump by about R620 over 3 years and this assumes electricity cost does not increase . in addition and IMPORTANT the customer always has a spare pump.
In 10 years almost every person I have explained this to has bought 2 pumps because it is sensible, valuable and honest advice in all respects.
If you need water volume not pressure then 2 pumps are always better than 1 choose low head, low wattage pumps and run in parallel. Switch one off when not really required and save electricity. If you have a minute take a look at pond pumps.com and learn a lot.
