1 Turbo II air-hydraulic pumps pplication & selection Power sources Linear clamps Work supports 122G Shown: PMG-542N, PCG-312N, PTG-312N, PTG-515N Turbo II air hydraulic pumps generate the hydraulic pressure you need using the air pressure you have available. The ir Saver Piston reduces air consumption and operating costs. They are ideal for providing the power and speed desired in simple clamping circuits. Turbo II airhydraulic pumps are best suited to medium and lower cycle applications. t only 75 d, the Turbo II series helps to keep noise level to a minimum. Quick and powerful hydraulic supply in an economical air-powered unit On-demand stall-restart operation maintains system pressure, providing clamping security External adjustable pressure relief valve (behind sight glass) Internal pressure relief valve provides overload protection Reduced noise level to 75 d Operating air pressure: psi enables pump to start at low air pressure** Reinforced heavy-duty lightweight reservoir for applications in tough environments Five valve mounting options provide flexibility in setup and operation Fully serviceable air motor assembly Select the required output 3 series Hydraulic to air ratio: 45:1 5 series Hydraulic to air ratio: 6:1 WVP-5 SURS-51 ** NOTE: From psi air inlet pressure.

36 Oil/oil intensifiers Pallet Components Valves Power sources Linear Clamps Work supports 99_55 Shown: PID-41 PID series When hydraulic pressure from an existing power source is limited, Enerpac oil-to-oil intensifiers serve to increase output pressure to satisfy the required application. High flow units intensify low inlet oil pressure to high outlet pressure Internal bypass valving enables high output flow rates Wide range of intensification ratios allows for adapting to various operating pressure requirements Compact and self-contained design allows for ease of installation Includes dump valve eliminating the need for an external pilot check valve Select fit of all internal components provides long operating life OS Intensifier principle When oil is supplied to the inlet (IN) port it flows freely past the check valves (CV) and the dump valve to the cylinder and advances it. s the inlet pressure increases the oscillating pump (OP) automatically increases the outlet pressure by the chosen intensification. Once the maximum pressure is reached, the pump frequency lowers and balances at the maximum pressure. PID Series IN R Low pressure OP CV1 PID-xxxF intensifier CV2 DV High pressure To cylinder Free flow from the cylinder to tank occurs when the directional control valve is switched to supply the R-port. 1 micron filtration is required on all ports in the circuit to ensure trouble free operation. Filters and flow control included. z PID-Series intensifier utilizes low pressure machine hydraulics to power clamping cylinders.
