How well will these pumps work in my situation?
There are four main questions that will help us determine if you have the correct circumstances for our RamPumps.
- How many litres per second can you get from your water source and what is the water source? e.g. creek, river, stream
- How many litres do you require per 24 hours and what are you wanting to use the water for?
- What is the vertical height that you want to pump the water to?
- What is the vertical fall you can get from the water source down to where the RamPump would be positioned? (keeping in mind that the optimum is a 10:1 ratio of height pumped to fall used with the drive pipe on a 1:4 incline)
It would also help to let us know what country you are in and do you have hilly terrain?
If you can answer these questions when you first contact us we will be able to give you a faster response and let you know if one of our pumps will be suitable for your situation. You may also find this diagram helpful as a reference.
How much can it pump?
Performance will vary, depending on the flow of water, the available fall for the drive pipe, and the height to be pumped. The following table will give you a rough idea. If required, our field consultant can provide a more accurate assessment and tell you which model best suits your requirements.
| RamPump Model | RamPump Drive Pipe Size | RamPump Water used litres per sec. | Water pumped in litres per day at 10:1 |
Water pumped in litres per day at 12.5:1 |
Water pumped in litres per day at 16:1 |
Water pumped in litres per day at 20:1 |
Water pumped in litres per day at 25:1 | Water pumped in litres per day at 32:1 |
Water pumped in litres per day at 40:1 |
