Energy Manufacturing Hydraulic Cylinders, Valves & Williams Pumps

Energy Manufacturing Co., Inc. has built custom-welded hydraulic cylinders, valves, pumps, and complete hydraulic power systems from Monticello, Iowa since 1944. Ligon Industries acquired the company in 2013, and it remains active, building directional control valves, log splitter valves, flow control and pressure relief valves, and the Williams line of hydraulic pumps for mobile and stationary industrial equipment. Northern Hydraulics supplies Energy Manufacturing cylinders, valves, pumps, and replacement parts, and cross-references Williams pump successor models when an original part number is discontinued or hard to source.

Energy Manufacturing Co., Inc. Product Lines & Series

The catalog spans custom-welded cylinders, the Williams pump family, and the valve lines used across log splitters and compact power units. Cylinder construction covers double-acting, single-acting, tie-rod, cushioned, rephase, linear feedback, telescopic, and position-sensing designs built to OEM specification. The bulk of what Northern Hydraulics stocks sits in the Energy Manufacturing hydraulic valves line, led by monoblock directional control valves and the log splitter valves that drive its log splitter packages and hydraulic power units.

Cross-Referencing Energy Manufacturing Co., Inc. Parts

The Williams pump line has a documented succession that makes cross-referencing straightforward. The Model 30 Series was replaced by the Model F98, and the Model 50 Series was replaced by the Model H98. The F98 is rated at 10 GPM at 1000 RPM, 2.64 cu in/rev displacement, and 5000 PSI maximum; the H98 is rated at 14 GPM at 1000 RPM, 3.4 cu in/rev, and 4000 PSI maximum. All Williams pumps share the standard 6-hole mounting pattern, so a successor model bolts to the same bracket as the original. If you have a legacy Model 20, Model 30, or Model 50 tag, or an obsolete cylinder or valve part number, we can identify the current Energy Manufacturing equivalent or an interchangeable replacement. Send the part number or nameplate data and request an Energy Manufacturing cross-reference quote.
