Hi all

I believe everyone has read about the new Spec pump that can run on 3 different settings, 0.45kW, 0.75kW, 1.1kW.

We have 12 in stock now and this pump really is great. We're running a special until middle November selling these for R3500!
PLUS...... We will arrange for you to collect in JHB and CTN so there's no additional courier costs if you're there.

Here's some info on it.

Report on Energy Saving Possibilities with the Speck 3-Speed Pump Motor.

Summary
A new pump, filter and cleaner were installed at an existing swimming pool and its performance measured over two months. It was found that considerably less energy (-35 % on Medium, and -55 % on Low) was required to move the same amount of water through the filter, than on High. If the water is moved without driving a pool cleaner, the remaining energy cost drops by a further 1/3. A winter maintenance plan for this size pool (75 000L) was successfully run at an energy cost of 20 Kwh/mo (R20.00), which is in a 1:40 ratio with the cost of running a conventional 1.1 KW pump full time.


Motivation.

In many countries across the world there is a strong focus on energy-efficiency and to replace appliances which are wasteful by new products designed to optimise their use of energy. Because electricity tariffs are rising very steeply in South Africa (doubling every 3 years), swimming pool owners will also start looking at ways to reduce the impact of pool maintenance energy on their monthly electricity account. It will be a commercial advantage to have factual information on how much energy/cost can be saved by the use of this innovative pump/motor system, and how to achieve this.

Scope of Tests and Analysis

The main idea was to install a complete system (Combi unit), including pool cleaner, temporarily at an existing pool, to obtain accurate results for a specific but fairly representative situation. The focus was on energy requirements rather than testing the performance of the equipment (e.g. how well the cleaner covers the underwater surfaces), although the two aspects are linked, and particularly when the aim is to reduce energy requirements. All directly relevant factors like voltage, current, input power, pressure, flow rate, and time were recorded. Circumstantial factors like water clarity, leaves on the bottom, were noted, and filter sand and leaf catcher were regularly cleaned.
The measurements were analysed in such a way as to indicate how energy could be minimised.

Details of the Swimming Pool

The size is approximately 10m x 5m x 1.5m (75 000 L) and it is situated in a garden with large trees around. The test took place in autumn/winter and large numbers of leaves landed in the water. The water surface was also exposed to dust during windy periods.
The water temperature was mostly 10 – 15 C, and nobody entered the water.

The Three Power (Speed) Settings.

It was observed that upon pressing any of the three buttons, the motor initially (for 5 min) operated at a higher rating, which is useful to get the water flow started. After settling down, the input power for the HIGH, MEDIUM and LOW modes over a term of many hours was measured as 900, 500 and 300 watts, respectively. There is a short maximum of close to 1 KW, lasting less than a minute after switch-on, but the motor never operates at this level for any extended period. Start-up is much more gradual and smoother than an induction motor, and switch-over to a different mode is also gradual.

Water Flow Rate.

The water flow rate was measured for three power settings, with cleaner running and with cleaner disconnected. The filter was back-washed and the two baskets were cleaned. The pump inlet was 40 cm above the water surface, and the pipe connections were fixed and similar for all measurements:

Speed setting Flow rate, L/hour
with cleaner no cleaner
High 8200 12500
Medium 7300 11100
Low 6400 9100

Calculations and Analysis

In the table below all the measurements and derived results are summarised. It was thought useful to compare the relative energies required to circulate the full pool content once through the filter, for all six settings given above.



In essence this shows that although it takes significantly longer to circulate all the pool water through the filter 1x at lower power settings, compared to the highest setting, significant energy savings can be achieved while moving the same amount of water through the filter. In fact, this is true whether the cleaner is connected or not. It can further be argued that the filter will trap suspended particles more effectively with slower water movement through the sand, and maybe the total running time (and energy use) can be further reduced, but this has not been measured. It will be a tricky measurement but the results would be valuable.
This also shows that if the cleaner always runs when maybe only filtering is required (after a boisterous swimming pool party), about 50 % more energy is required to move the same quantity of water. To save this energy, unplug the cleaner and reduce the filtering time by 1/3.
Although these measurements and derivations are exact for this specific installation only, other installations will mostly not be drastically different, and the trends and savings will form a guide for more general use.

Choosing an energy-efficient strategy for a swimming pool.

It is informative to look at both extremes of possible filter usage, and then make an informed choice for maintaining a domestic pool in a cost-effective way.
• As a worst case a 1.1 KW filter pump motor can be operated 24/7 (which does happen in some households, even if only to oxygenate a koi pond). The monthly electricity consumption resulting from this is 792 KWh, which adds nearly R800.00 to the electricity account at the present (July 2010) tariff of R1.00/Kwh (VAT incl) in Pretoria.
• At the opposite end of the spectrum the filter and cleaner could be run for only 2 hours per day at the 300 w setting in mid-winter when nobody swims, as was done in this case. This meant that the pool water was turned around once in six days only, but it appeared normal. The monthly electricity consumption resulting from this is less than 20 KWh, which adds only R20.00 to the electricity account.
This is a staggering 40:1 ratio, which illustrates the potential for better energy-efficiency in domestic swimming pools. In summer the filter might need to be run for longer and the energy usage might increase to 40KWh (4 hrs/day on “low” and 4hrs/mo on “high”). This is still 55 % less energy than needed by a 900 w pump setting to achieve the same cleaning effect. Compared to the common 1100 w pump, the saving will be > 60 %, assuming the owner took steps to reduce his energy costs as well, e.g. reduced the daily timer setting to about 3 hours /day, with energy usage of 100 Kwh/mo.
If he decides to rather replace his old pump by the new 3 speed pump, his monthly saving of 60 KWh would cover the purchase price in less than three years, in view of the known future increase in electricity cost. Normally pool owners do not try to optimise the use of their old equipment as meticulously as this and will save more than 60 KWh/month by switching over, and will recover the cost of the new pump in much less time.

Relevance of 3 Speed Pump to other Applications.

Apart from domestic swimming pools, this new pump can benefit other installations even more: koi fish ponds, for example, are sometimes fitted with a 1.1 KW pump which runs continuously mainly to oxygenate the water, although this could be done with a small fraction of this power, and the biological filter needs only a low flow rate as well; it is only the normal coarse sand filter which needs to be back-washed with a strong current. Most of these persons are unaware that this is the main cause of their very high electricity accounts.
Big swimming pools at schools and gyms are equipped with multiple pumps, and suffer very high running costs because it is never questioned whether full power is required 24/7 to chlorinate the water and distribute heated water across the pool area. There is big scope for marketing this pump in this market.

General Observations made during this Test

General observations about low power operation: the pool cleaner still works quite effectively, although slower, with a 300w motor and will pick up leaves from the bottom, up to 4cm long (e.g. Celtis africana) but needs several passes to clear all. It only sucks up leaves which are directly in its path and which drift closely past its ports on top of the flap. As the leaf trap fills up, the cleaner slows down gradually due to increased water resistance, and the trap must be emptied regularly. If the pool and filter are relatively clean to start with, the cleaner will work unattended at low power for long hours. When the cleaner was manually assisted to visit all the neglected areas on the floor, it could make a complete sweep of the pool in less than an hour, even on the low setting.
All in all this is an exciting new product which seems to have been thought through very carefully, and which works well. Cumulatively about 100 hours of operation in all the modes were logged during evaluation, without any mishap. For an owner it is comforting to have a pool maintenance installation which can be adapted for short periods of intensive pool utilisation (summer holidays), but can then easily be reset to a low energy mode when all is quiet. For some owners the saving of energy and contribution to less CO2 into the atmosphere by adopting more energy efficient techniques, are even more important than money saving.

Importance of low water flow losses

From an energy efficiency view point it is advisable to choose filter and pipe sizes in a new installation as for a conventional 1 KW fixed speed pump motor, even if it is intended to run the new system mostly at a lower setting. In all cases the extra cost of slightly oversized pipe diameter will be recouped by energy savings. New owners should be well instructed on regular cleaning of leaf traps and filter, in order to keep the water flow resistance low, and thus avoiding the mis-use of motor power just to overcome high flow resistance.
It might be a good idea (also from an energy efficiency view point) if the pool shop measures the water flow rate of a new installation and set the timer period accordingly, as in the table above, rather than unjustifiably long periods of 8 – 12 hours /day, although even in such a case the 300 w setting will be 2/3 less costly to operate than an old 1 KW fixed speed pump.
