The HPP18-2 Hydraulic Power Pack is designed to provide hydraulic fow and pressure for operation of HTMA Type I and Type II hydraulic tools. The power pack is equipped with an 18 HP gas engine. The power packs are all equipped with air-to-oil coolers with suction fan mounted to the power shaft on the engine. The fuel and hydraulic systems are self-contained with the required reservoir， fltration and level indicators.
The hydraulic system consists of a hydraulic system fuid reservoir; flter assembly， single (HPP18) or tandem pump (HPP18-2)， and a wide variety of fow controls. The flter element is a “spin on” type element for easy replacement. The flter housing has a pressure bypass valve to divert fuid directly to the tank in the event of a restricted flter. Only the hydraulic pumps are called out in the parts section of this manual. Pressure hoses from the pumps are connected directly to a control module， which contains a relief valve， a fow control valve， and pressure and return ports. 5 gallon hydraulic reservoir for cooler oil operation.
