<p>A hydraulic power assembly (10) includes an electric motor (30) disposed on a removable top (26) outside a tank (12) defining a chamber (25). A first pump (32) depends from the removable top (26) and into the chamber (25) and includes a first inlet (34) and a first outlet (35) to deliver fluid to a fluid line (36) and a fluid distribution manifold (38) disposed on the removable top (26). A leakage line (52) extends from the pump (32) and through the removable top (26) and back through the removable top (26) and drains into the chamber (25) for determining if the pump (32) is operating efficiently. A heat exchanger (78) is adjacent the motor (30) for cooling the hydraulic fluid as it is returned into the chamber (25) thereby cooling the fluid in the chamber (25). The tank (12) also includes a liner (74) for reducing the noise of the pump (32).</p> |
