Use the complete Clemson ram-pump plan and a qualified installer to lift a fraction of a flowing water source without an electric motor.
- 1Natural falling-water source and rigid drive pipe
- 2Commercial waste and delivery check valves
- 3Rated pressure chamber; professional review
- 4Delivery uphill; remaining water drains safely
Site and operating requirements
- Survey net head, usable seasonal flow, flood level, debris and legal access. Select a design for that measured resource.
- Obtain complete shaft, bearing, mounting, guard and electrical drawings. A photograph is not a tolerance or load specification.
Tools and measuring equipment
- Tape/level and safe survey tools, timer and measured collection vessel for suitable small flows, tachometer and rated load/meter set; workshop tools follow the full drawings.
Output and operating conditions
Planning relationship: delivered flow ≈ efficiency × drive flow × fall / delivery lift. Most drive water exits the waste valve; this is powered by falling water.
Clemson-specific plan needs about 1.52 m minimum fall and nominal 1¼ in drive pipe; its length range is about 4.9–31.7 m. Use its full design tables, not these figures alone.Parts, quantities and dimensions
| Part | Quantity | Specification / dimensions |
|---|---|---|
| Intake and anchored drive pipe | per plan | Screened intake, rigid continuous drive pipe, foundation and unobstructed waste drain. Nominal diameter is not measured outside diameter. |
| Commercial rated valves and fittings | per source BOM | Plan includes nominal 1¼ in inlet valve/tee/union, swing waste check and spring delivery check; ¾ in outlet fittings and reducers. Match exact orientation and pressure ratings. |
| Engineered pressure chamber and gauge | 1 set | Clemson lists a 4 in × 24 in chamber and air-filled inner tube with specified rated fittings. Installer must verify surge pressure, current materials and relief requirements. No 3D-printed pressure parts. |
Preparation and component checks
- Read the complete linked method, mark its edition, and create a measured component list and a labelled sketch before starting. Keep experimental changes separate from the published procedure.
- Prepare the work area and inspect every component. Run the lowest-risk dry or unpowered check before water, heat, moving parts or crop material are introduced.
Procedure
- 1
Measure seasonal source flow, vertical fall, delivery lift and route length. Check legal abstraction, water use and downstream waste drainage.
- 2
Select one complete Clemson configuration. Have an installer review the pressure design and every component rating before procurement.
- 3
Install a screened intake with the source-required submergence and no air-trapping high points in the anchored rigid drive pipe.
- 4
Assemble valves, chamber, gauge and delivery line exactly to the reviewed drawing with isolation and safe waste discharge.
- 5
Commission using the complete manual and a controlled exclusion area. The installer must check cycling, air cushion, leaks and pressure before opening normal service.
- 6
Measure both delivered and wasted water over a timed interval; record lift and drive flow to calculate the actual result.
Safety and inspection
Professional pressure-system consultation is required. Keep people clear of pressure joints; never use a bottle or a printed vessel as an air chamber. Water still requires suitability testing.
Verify the result
Use measured flow and lift, not a viral claim of gallons lifted. A gauge maximum is not a safe operating-pressure specification.
Measurement log
- Drawing revision, measured dimensions, resource inputs, speed/flow, loaded output, trial duration and every observed fault. Mark unknown values as unmeasured.
Maintenance and repeat checks
- Inspect intake screens, anchors, check valves, air cushion and waste drainage routinely and after floods. Isolate and depressurise before service.
- Provide overflow or controlled delivery arrangements: a closed trough valve can stop cycling and may require a manual restart.
Troubleshooting
- No output, abnormal heat, noise, vibration or leaks
- Stop and isolate first. Check the documented input, load compatibility, alignment and connections; keep guards fitted and refer specialist systems to their installer.
