Kemmler Analysis of Pump Used In Rossi Experiment

Appendix 11 to New Energy Times Report #3

By Angela Kemmler

The Andrea Rossi trio used a particular pump in all its public experiments.

It is a yellow pump made by the U.K. manufacturer LMI (http://www.lmi-pumps.com). LMI calls these pumps "electronic metering pumps," so they are not toys but designed to be programmed to deliver a particular precise flow of fluid. These metering pumps are smart; they do not pump liquid in a constant way.

They pump a certain volume of fluid at a certain time interval. Every pump action can be heard as a loud "tuk tuk tuk." LMI sells a variety of metering pumps.

Giuseppe Levi and Rossi never explained which type of LMI pump they were using; they never told the manufacturer. This is unscientific behavior. Many people on blogs found out the possible type of pumps. There was, however, a problem: There were two pumps that looked the same but had different specifications.

That was until Ny Teknik reporter Mats Lewan came to Bologna. He was the person who wrote the exact type of pump in his report. So, since then, we all know that it is an LMI P-series 18 pump (or simply LMI P18).

Specifications published by the manufacturer:
max 3.20 GPH (12.1 l/h) 22 psi (1.5 Bar)
max stroke frequency = 100 / minute
max stroke volume = 2 ml

Manual of the pump:

Maximum throughput of the pump is reached at 2 ml volume and 100 strokes/min. The flow can be calculated by multiplying the figures.

For example, 2 ml x 100 = 200 ml/min = 12,000 ml/hour = 12 liters/hour.

Now let's look at several sample Rossi experiments.

Jan 14, 2011:
Frequency = 60/min, volume assumed to be 2 ml (in favor of Rossi) = 120 ml/min = 7,200 ml/hour = 7.2 l/hour. The frequency can be heard easily by listening to the videos produced and published by Rossi. Rossi says, however, that the flow was 292 ml/min (=17.5 l/hour). This is impossible, because it is beyond the specification (see above) and because the frequency is not 100 but 60.

April 28, 2011:
This is the one where Lewan "tested" the E-Cat. He personally checked the water flow by weight. In his report, he tells about a flow of 63-69 ml/min.

Listening to the pump, we hear a stroke frequency of 32/min. 32 x 2 ml = 64 ml/min = 3.84 l/hour. So, in this case, the value given by Lewan is +/- equal to the value calculated. I suppose that, in this particular case, nobody could cheat that value; perhaps it was possible to cheat the current/heating power.

June 14, 2011:
As shown in Steven Krivit's video, we hear a "tuk tuk" about every 2.5 or 3 seconds. We see regular movements of the hose. Frequency was 20 to 24 strokes per minute. Assuming (in favor of Rossi) a volume of 2 ml, we have 40 to 48 ml/min = 2.4 l/hour to 2.88 l/hour. What does Rossi say in the video? 7 l/hour. This is a major inconsistency.
