Home-made Hydraulic Ram PumpHome-made Hydraulic Ram PumpThis information is provided as a service to those wanting to try to build their own hydraulic ram pump. The data fromour experiences with one of these home-made hydraulic ram pumps is listed in Table 4 near the bottom of thisdocument. The typical cost of fittings for an 1-1/4" pump is currently $120.00 (U.S.A.) regardless of whethergalvanized or PVC fittings are used.Table 1. Image KeyClick here to see a picture of an old-style assembled ram pump with a threaded plug(see notes below concerning glue cap (#16) versus threaded plug)1 1-1/4" valve 10 1/4" pipe cock2 1-1/4" tee 11 100 psi gauge3 1-1/4" union 12 1-1/4" x 6" nipple4 1-1/4" brass swing check valve (picture) 13 4" x 1-1/4" bushing5 1-1/4" spring check valve 14 4" coupling6 3/4" tee 15 4" x 24" PR160 PVC pipe7 3/4" valve 16 4" PVC glue cap8 3/4" union 17 3/4" x 1/4" bushing9 1-1/4" x 3/4" bushinghttp://www.clemson.edu/irrig/Equip/ram.htm (1 of 7) [1/13/2005 12:42:54 PM]
Home-made Hydraulic Ram PumpAll connectors between the fittings are threaded pipe nipples - usually 2" long or shorter. This pump can be made fromPVC fittings or galvanized steel. In either case it is recommended that the 4" diameter fittings be PVC fittings toconserve weight.Conversion Note: 1" (1 inch) = 2.54 cm; 1 PSI (pound/square inch) = 6.895 KPa or 0.06895 bar; 1 gallon per minute =3.78 liter per minute. PR160 PVC pipe is PVC pipe rated at 160 psi pressure.Assembly and Operation Notes:Pressure Chamber - A bicycle or "scooter tire" inner tube is placed inside the pressure chamber (part15) as an "air bladder" to prevent water-logging or air-logging. Inflate the tube until it is "spongy" whensqueezed, then insert it in the chamber. It should not be inflated very tightly, but have some "give" to it.(No information is available concerning pressure chamber sizes for the various sizes of ram pump.Make one somewhat larger for larger pumps - for instance, try a 6 inch diameter x 24 inch long pressurechamber for a 3 inch ram.)A 4" threaded plug and 4" female adapter were originally used instead of the 4" glue-on cap shown inthe image, This combination leaked regardless of how tightly it was tightened or how much teflon tapesealant was used, resulting in water-logging of the pressure chamber. This in turn dramaticallyincreased the shock waves and could possibly have shortened pump life. If the bicycle tube should needto be serviced when using the glue cap the pipe may be cut in half then re-glued together using acoupling.Valve Operation Descriptions - Valve #1 is the drive water inlet for the pump. Union #8 is the exit pointfor the pressurized water. Swing check valve #4 is also known as the "impetus" or "waste" valve - theextra drive water exits here during operation. The "impetus" valve is the valve that is operated manuallyat the beginning (by pushing it in with a finger) to charge the ram and start normal operation.Valves #1 and #7 could be ball valves instead of gate valves. Ball valves may withstand the shockwaves of the pump better over a long period of time.The swing check valve (part 4 - also known as the impetus valve) can be adjusted to vary the length ofstroke (please note that maximum flow and pressure head will be achieved with this valve positionedvertically with the opening facing up). Turn the valve on the threads until the pin in the clapper hinge ofthe valve is in line with the pipe (instead of perpendicular to it). Then move the tee the valve is attachedto slightly from vertical, making sure the clapper hinge in the swing check is toward the top of the valveas you do this. The larger the angle from vertical, the shorter the stroke period (and the less potentialpressure, since the water will not reach as high a velocity before shutting the valve). For maximum flowand pressure valve #4 should be in a vertical position (the outlet pointed straight up).Swing check valve #4 should always be brass (or some metal) and not plastic. Experiences with plasticor PVC swing check valves have shown that the "flapper" or "clapper" in these valves is very lightweight and therefore closes much earlier than the "flapper" of a comparable brass swing check. This inturn would mean lower flow rates and lower pressure heads.The pipe cock (part 10) is in place to protect the gauge after the pump is started. It is turned off after thepump has been started and is operating normally. Turn it on if needed to check the outlet pressure, thenhttp://www.clemson.edu/irrig/Equip/ram.htm (2 of 7) [1/13/2005 12:42:54 PM]
