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.

Make sure the fittings of the two-stage pump match your log splitter before you buy it.

The Central Hydraulics 99742 two-stage pump, with a 1/2-inch shaft, provides 11 gallons per minute (gpm) of pumping action, and a maximum operating pressure of 3,000 pounds per square inch (psi).  It runs at a maximum of 3,400 rpm. Its hydraulic inlet uses a 3/4-inch hose, while its hydraulic outlet uses a 1/2-inch hose.  This pump costs $104 as of December 2010. It works with any log splitter that utilizes an external-source hydraulic system.
