Hydraulic Hand Pump
A Morehouse hand pump is a basic and low-cost system for providing hydraulic pressure for a UCM (Figure
5). When this system is purchased with a UCM, the hydraulic jack is acvated by a hand pump assembly that
advances the ram quickly and then more slowly unl the desired load is achieved. The high/low operaon is
switched manually and can be switched at any desired load. The pump is connected to the hydraulic jack using
a hydraulic hose assembly with a quick-disconnect coupling.
Cauon: Before use, check the hose and ngs for any potenal leaks.
