Selecting the Right Hydraulic Ram Pump
1. Determine Your Water Flow Rate
To select the appropriate pump size, you first need to measure the flow rate of your water source. This is essential as each ram pump model has a minimum flow rate it requires to function efficiently.
- How to Measure Flow Rate:
- Fill a 5-gallon bucket from your water source and time how long it takes to fill.
- Use the formula: Flow Rate (GPM) = 300 / Fill Time (seconds).
2. Assess Your Head Pressure
Head pressure is the vertical drop from your water source to the pump. This measurement is crucial as it influences the pump’s ability to lift water.
- Methods to Measure Head Pressure:
- Use a garden hose and lift the end until the water stops flowing. Measure the height from the water surface to the hose end.
- Alternatively, a pressure gauge can be used to convert psi to feet (psi / 0.433 = feet of head).
3. Calculate Lift Height
Determine how high you need to pump the water. The hydraulic ram pump operates on a principle that allows it to lift water up to 7 times the head pressure.
- How to Determine Lift Height:
- Use Google Earth to find the elevation difference between the pump and the point of use.
- A clinometer or line level can also help in measuring the incline.
4. Assess Daily Water Needs
Estimate how much water you require daily. This will guide you in selecting a pump that meets your supply needs.
| Pump Size | Max Daily Output |
|---|---|
| 1/2″ Pump | 360 Gallons |
| 3/4″ Pump | 720 Gallons |
| 1″ Pump | 1080 Gallons |
| 1-1/4″ Pump | 1440 Gallons |
Performance and Maintenance of Hydraulic Ram Pumps
Performance Factors
- Flow Rate and Head Pressure: The performance of a hydraulic ram pump is highly dependent on the flow rate and head pressure. Ensure your water source provides sufficient flow and pressure for the pump to operate effectively.
- Installation: Proper installation of both the drive and delivery pipes is critical to the pump’s efficiency. Ensure that the pipes are sealed correctly to prevent leaks.
Maintenance Tips
- Regular Inspection: Periodically check the pump and its components for signs of wear or damage. Pay particular attention to the waste valve, as it plays a crucial role in the pump’s cycling.
- Cleaning: Ensure that the inlet is free from debris to prevent clogging. Use strainers if necessary to keep out leaves and sediment.
- Lubrication: Apply lubricant to moving parts as needed to ensure smooth operation.
- Winterization: If you live in an area with freezing temperatures, take precautions to winterize your pump to avoid damage.
Practical Tips for Choosing and Using Hydraulic Ram Pumps
- Choose Quality Materials: Ensure that the pump and pipes are made from durable, lead-free materials to ensure safety and longevity.
- Consider Local Regulations: Check for any local guidelines or regulations regarding water pumping and usage.
- Plan Your Setup: Before installation, plan the layout of your pipes to minimize bends and restrictions, which can impede flow.
- Educate Yourself: Familiarize yourself with the principles of hydraulic ram pumps to maximize their efficiency and troubleshoot issues that may arise.

FAQ
What is a hydraulic ram pump?
A hydraulic ram pump is a device that uses the energy of flowing water to pump a portion of that water to a higher elevation without the need for electricity or fuel.
How does a hydraulic ram pump work?
It works by utilizing the water hammer effect, where a sudden change in water flow creates a pressure wave that allows some water to be forced upward through a delivery pipe.
What is the minimum head pressure required for a hydraulic ram pump?
Most hydraulic ram pumps require a minimum head pressure of at least 2.5 feet to operate effectively.
How do I measure my water flow rate?
Fill a 5-gallon bucket from your water source and time how long it takes to fill. Use the formula: Flow Rate (GPM) = 300 / Fill Time (seconds).
