Two-Stage Hydraulic Pumps for Log Splitters

Hydraulic log splitters utilize a hydraulic pump that drives a piston to split logs. A two-stage hydraulic pump for log splitters has two pumping sections, one to apply the high pressure needed to split a log, the other operating at low pressure to withdraw the piston. Hydraulic pumps are rated by pumping action in gallons per minute. It's best to select a replacement with the same specifications as the one already on your log splitter.
