GARDEN WATERING FLOW RATE GUIDE
The SJ35-04 pump models can supply a variety of garden watering applications,
such as:
- A garden hose with a spray nozzle fitted, or;
- A garden spray system with up to 25 microjet sprays, or;
- A garden dripper system with up to 200 garden drippers (4 litres per hour drippers), or;
- Two small impact sprinklers
The larger SJ60-08 model is capable of up to double the above,
though still suitable for running a single garden hose.
With the correct selection of pipework, valves and automatic irrigation controller, the range of models can even be used to power a fully automated watering system.
Your garden watering professional can give you the best advice on how to utilise the valuable rainwater you have captured for the most efficient usage in your garden.
