Submersible Power UnitReplacement of the pump unit can dramatically improve the overall performance of your hydraulic elevator. The pump unit consists of several key components of the elevator system. The motor, pump and control valve are all contained in this one unit. All these components have a limited life expectancy, and when individually replaced can add additional costs and, above all, increase down time.
