ABSTRACT:
The unit comprises a mobile chassis having an enclosure mounted thereon, in which enclosure are compactly and efficiently confined an air-operated hydraulic pump, a water conduit for admitting water to the pump and for discharging pressured water therefrom, and a compressed-air conduit, for admitting operative compressed air to the pump, together with a pressure regulator for the air. The enclosure has a control panel through the face of which are mounted air and water inlet connectors for the conduits, and a water outlet connector. Air and water inlet valves, interposed in the conduits, are also mounted on the control panel, as well as a water discharge valve; the latter is interposed in the discharge end of the water conduit. Finally, air and water pressure-indicators, which communicate with the respective conduits, are fixed in the panel, and a pressure-setting regulator, which communicates with the air conduit, is secured in the panel.
