[QUOTE="blackdoggy, post: 889860, member: 18741"] A two stage might be the norm for splitters due to the ability to use a small engine to run the pump but for cost reduction go with a single stage Dynamic gear pump from northern tool. I did a check a little while back and the Dynamic gear pump is technically more powerful than a more expensive two stage pump. Your GPM is only half of what you need to look at when buying a log splitter pump GPM is your speed but what will do the splitting is the cubic inch of the pump. If you go to the Haldex site and download a manual on the two stage barnes pumps they sell and download a copy of dynamics's gear pump book and you will see that the 11 GPM two stage actually runs several GPM less than the 11 GPM stated. The dynamic model GP-F20 will run more GPM per minute and a higher CI than almost any two stage pumps. Another way to look at it if you have the manuals is a $100 dynamic pump will meet or beat the $120 barnes pump. [/QUOTE]
