On our local ebay equivalent. 5 kW in. 14 kW out Pure magic! http://www.trademe.co.nz/Business-farming-industry/Farming/Other/auction-55651233.htm In = 6.5 HP ~= 5kW Out = 40 litres/minute x 3000 psi 40 litre = 0.04 m^3 3000 psi ~= 205 atmospheres ~= 21 MPa Power = energy/second = 0.04 x 21E6/60 = 14 kW 14/5 = 2.8 x energy or 1.8x free energy. Who needs a magnetic black box with these for sale. The big one from the same seller is just as good. RM E&OE

The key phrase is "2 stage log splitter pump". The similar pumps I've seen locally have a low pressure stage that moves lots of fluid, then changes to the high pressure / low volume stage automatically when the line pressure increases. Specifically intended for moving a hydraulic ram quickly to get it to the position where the actual work is needed and ideally suited for log splitting applications. dwayne -- Dwayne Reid <spam_OUTdwaynerTakeThisOuTplanet.eon.net> Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 22 years of Engineering Innovation (1984 - 2006) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.

I have one of the larger models of these on my splitter. At some pressure setpoint it switchs to the other stage to get more pressure at reduced flow. BTW is everything in NZ that expensive? I can buy a new pump, same model as the auction was for, from multiple sources for US$120. That is only NZ$200! Perhaps that's why it didn't sell... Aaron
