PRODUCT INFO:

Inverter Variable Speed Drive For Commercial Pool Pumps below 3HP is a solution designed to greatly reduce the running costs of commercial pool circulation pumps and improve the efficiency of swimming pool filtration.

Swimming pool pumps invariably run at higher flow rates than necessary, to allow for the power needed when backwashing. Inverter Variable Speed Drive For Commercial Pool Pumps Up To 3HP Inverter technology enables you to control pump flow-rates during the filtration period, which is over 95% of the time.

Swimming pool pump energy conservation is evolving, it’s now possible to reduce the running costs of your commercial pool pump by as much as 33% simply by reducing your pump speed to 80% for 95% of the time and the running it at 100% power while backwashing for the remaining 5% of the time.

This Inverter Variable Speed Drive is Suitable For The Following Pumps:

BP Range, BPH Range, Calpeda, Modern, Hurricane, Giant, Great Giant, Hydrostar, Columbia, Aral, Maxim, Shark, Speck, Hayward, Waterco, Starite and DAB

Call us on 01322 554 870 for us to assist choosing the correct model.

How does it work?

Example of cost saving Pump size 2.5HP (1.865kW) 3 phase pump.

Operating time 24 hours / 7 days a week / 52 weeks- Running Costs £5,540 Per Year

Cost of unit £891.00

Suggested Cost of installation £350.00

Total cost £1241.00

Based on electricity at 34p per kWh

The cost of running the pump at 80% of the speed for 95% of time and 100% of speed for 5% (backwash) is £4055 Per Annum.

Cost saving is £123.75 per month and 10 months payback on installation.

Understanding Pump Affinity Laws

Understanding pump affinity laws will allow you to explain, demonstrate and calculate how a change in motor speed impacts;

• flow rates against resistance

• power consumption

• operating costs

1. The change in flow is proportionate (equal) to the change in speed. If we halve the speed we halve the flow

2. The change in pressure is equal to the speed change factor squared. Operating pressure will be 1/4 of the original pressure

3. The change in power consumption is equal to the speed change factor cubed. Power consumption will be 1/8 the original consumption

As an example, if we take a pump with the following characteristics:

• Motor speed: 2850 rpm

• Flow rate: 302 lpm

• Pressure: 8 metres head

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts
