This innovate pump design offers a compact household water pressure pump with integrated variable speed drive controller. Having a variable speed means the supplied water pressure is constant as demand increases and pump efficiency is maximised, saving you power.
Constant Pressure Clean Water Pump with VSD
Paddock™ are known for making amazing products and this pump is no exception. The pump offers commercial pump features at a domestic pump price. This pump is ideal for most homes drawing water from a rain water tank for household applications such as showers, taps and watering the garden.
Most domestic water pumps on the market run a fixed motor speed. As you open and close the tap and change your water demand, the load on the motor changes as does the electrical power draw. The alternative to this common design is to change the pumps impeller speed which in-turn changes the amount of water delivered and its pressure. Changing the pump speed to meet demand is a far superior way to run a pump but it's rarely done due to the higher costs associated with the pump controller and motor manufacture. Times are changing and now Paddock™ has delivered a variable speed, constant pressure pump, at a price all households can afford.
This pump is a ideal replacement for the Grundfos SCALA2 pump and offers some great improvements to make it better in our opinion.
Low Noise Pumping
A major advantage to running pumps at variable speeds is the reduction in noise. Pumps generate greater noise and vibration when the system backpressure changes. Running a pump at full speed against a closed tap until the pressure switch activates is relatively noisy. The Paddock™ variable speed pump is up to 70% quieter then similar pumps without a integrated speed controller.
Economical Water Pumping
Pumps are high power users and when you run a pump at full speed against a closed or partially closed valve, it's wasting power. The better solution is to slow the pump down so you still achieve the same pressure with less wasted energy. The Paddock™ variable speed pump can save up to 60% over fixed speed pumps which saves you on the electricity bill.
Self Priming Operation
These pumps will lift water 6m vertically on their suction side, saving the operator having to manually prime the unit. This feature is fantastic for people who need to mount the pump a distance away from the supply and the vertical lift capability can be converted into far greater horizontal distance draw. With the ability to self prime, the pump will draw the water from the source without operator intervention.
Smart controls and Integrated Protection Systems
These pumps employ modern electrics to ensure your pump not only performs, but also lasts the test of time.
Pumps can be damaged if they are left to run dry, such as when your tank empties unexpectedly. Such operation can overheat and damage the pump components and even trip the household power supply. This damage is avoided with the Paddock™ range, as they include a integrated dry run protection switch inside the pump. If loss of flow is detected, the pump will rest for 30 minutes before attempting a restart. If this rest/restart cycle repeats 5 times without detecting flow, the pump will go into a permanent shutdown state until it is manually reset.
Thermal overload protection is also standard on all models and adds to the overall package this pump delivers. Thermal protection is important for pumps that could be operating in a confined space and will alert the operator to a potentially damaging state of operation.
Quality Components and Exceptional Build Quality
Paddock™ are known for their quality products at a fraction of the cost of other leading brands. These pumps are no exception and have been proven to last well in the harsh Australian environment. They are suitable for both domestic and commercial installations with powerful motors and smart electrics integrated as standard.
The pump wet end components are robust and serviceable. Modern poly plastic materials combined with corrosion resistant stainless steels are used to achieve an extremely long operating life. A full range of replacement parts are available to service these pumps.
These pumps are suitable for continuous duty operations in the hot Australian environment. The quality motors deliver performance without waiver and the pumps protection systems are standing by if an abnormal operating case is detected. Users can expect stable operation and a long design life from the Paddock™ range of pumps.

The following is provided as a guide only, customers should do their own research and engage a professional to ensure the pump selected is right for their application.
Selecting a pump can be confusing and difficult to summarise for the less technically minded. As a guide, we suggest when selecting a household water pressure pump, first determine your target water flow rate.
||No. Taps running at once
||Target Flow (L/min)
|Small Cottage - 1 x tap and 1 x shower running
|Small house - 2 x taps, toilet flush and shower
|Average house with modern appliances - same as above with dishwasher/ washing machine also running
|Larger house with multiple bathrooms being used at once
|Massive House, some irrigation outdoors
Next you need to determine what pressure you need the target flow rate at. A rule of thumb is to target 270 kPa (~40 psi) at the most upper floor tap in your house. So if you were a single storey house with a shower above head height, you want your target flow rate at ~300 kPa, measured at the pumps discharge.
If you're multi-storey, you need to add ~30kPa per level. Divide your pressure in kPa by 9.8 to get the pump head required.
||Target Pressure (kPa)
|2 Storey House
|3 Storey House
|Add ~30 kPa per additional storey (assumes ~3m floor to next level floor spacing)
When checking the performance curve, we can see the pump will flow ~55 L/min at ~30m head equating to the target pressure for most single storey buildings.
For a 2-storey home, the pump series will deliver ~46 L/min.
For a 3-storey home, the pump can deliver ~40 L/min enough to run multiple top level taps at once.
Note: the above guide is an extremely simplified summary of a more complex hydraulic calculation. Flows, pressures and overall performance will be impacted by pipe lengths, pipe diameters, filters and pump elevation relative to supply. If you have any doubt or concern about your installation, please don't rely on the above guide to size your pump and rather engage a engineer or plumber to design for you.
