Pumps

Rainwater harvesting offers many benefits, including: 

• Savings: Using rainwater as a natural source of water can reduce your utilises bill, offering significant savings over time. 
• Required water source: In some areas, rainwater harvesting can be a crucial source of water drinking and other uses. It is recommended in several jurisdictions around Australia to reduce reliance on main water supplies. 
• Environmental benefits: Rainwater harvesting offers environmental benefits including decreased stormwater runoff and reduced near for main water usage. When you take advantage of rainwater harvesting, you can contribute to more sustainable water usage. 

There are a few factors to consider when choosing a water pump for rainwater harvesting:

• Pump type: With multiple pump types available on the market, you’ll have to decide which is right for your task or purpose. For example, submersible pumps are used to “push” water rather than “pull it”, and are less noisy and more space-efficient. Jet pumps are generally available for a cheaper upfront price and can be used for a more versatile range of functions.
• Required flow rate: Flow rate determines how quickly water is delivered. Required flow depends on how your rainwater tank or other water source is used. Flow rate is usually measured in litres per minute.
• Required head: Head is the vertical distance that water must be moved by a pump to its destination. This is an essential consideration, as different pumps are designed to move water at different vertical distances.
• Required pressure: Purchasing a pump with the right pressure ensures that water reaches its intended outlet with the required force. Pressure for water can be calculated using P(kPa)=9.81xhead(m).

Water pumps require a range of accessories to properly function. You can purchase many of these key accessories from Bromic, including:

• Changeover valves: Bromic’s changeover valve offers economic and efficient use of stored rainwater. These valves are a smooth and reliable way to access rainwater.
• Controller kits: Bromic offers a number of controller kits, automatically performing tasks including starting and ceasing water supply and changing between harvested water and mains water. Bromic’s controller kits are weatherproof and fully compatible with Waterboy™ pumps.
• Submersible pump hose kit: This easy-to-use hose kit allows water to be dispersed from a work site.

Bromic’s range of Waterboy™ jet pumps are ideal for an array of domestic and commercial applications, owing to a broad range of design features:

• Bromic Waterboy™ pumps have a highly durable design, allowing them to function well over a long period of time. They are capable of withstanding a range of weather conditions while continuing to operate well. 
• The Waterboy™ range offers an extensive series of different pumps, allowing you to find the perfect product for your needs. You can browse jet pumps, submersible pumps, multi-stage pumps and more.
• Thanks to this range, it’s easy to find a pump for whatever application you require. Many individual pumps in the range are also highly versatile and suitable for a range of functions.
• Many pumps in the Waterboy™ are self-priming. Manual priming can be complex with the potential to damage your pump. Self-priming pumps are more intuitive and make for easier set-up.

Submersible pumps sit within water tanks or other water sources. While other types of pumps work by “pulling” water, submersible pumps “push” water upwards.

Submersible pumps often use centrifugal motors, using impellers to increase water pressure and push the water out through the pump outlet. Submersible pumps generally do not need to be primed.

We have a 3kW pressure controller (7575372) which controls the pump supply for the rainwater. We have a hydro switch (7575029) which can be added to this controller to allow the mains water to be connected so water can be supplied even if there is no tank water. 

Either there is no controller connected or it is not plugged in correctly. Read instruction manual to see how to connect the controller.

Shouldn’t use this pump if its in a place where water freezes. Water will expand when it freezes inside the pump and will cause the pump to crack. The water should be fully drained from the pump and pipes during these periods. 

Check on the flow vs head chart. If you decrease the flow the pressure will increase. More pressure can also be achieved with less bends and height in the piping. Pressure=head*9.81*specific density
