  • Page 5 • Some PID Series intensifier models are capable of providing a maximum pressure above 5000 psi [350 bar]. Operation at pressures above 5000 psi [350 bar] requires the use of high pressure fittings. Contact Enerpac for additional details. • Read, understand and follow all communicated safety precautions and related information included on the following pages of this manual.

  • Page 14 5.7 Directional Control Valve Recommendations • To prevent hydraulic oil leakage from occurring, it is strongly recommended that an open center control valve be used with the intensifier. See re 4, upper view. Figu • Use of a closed center control valve is not recommended. See re 4, lower view.

  • Page 15: Operation

    6.0 OPERATION 6.1 PIDxxxA and PIDHxxx Models When hydraulic oil enters the inlet (IN) port, it freely flows through the check valves (KV1, KV2) to the cylinder. The cylinder then advances. When cylinder pressure reaches the supply pressure, the intensifier oscillating pump (OP) automatically starts oscillating and begins to increase the pressure in the cylinder by the designated intensification factor (varies by intensifier model).
  • Page 16 6.2 PIDVxxxA and PIDVHxxx Models The PIDVxxxA and PIDVHxxx models function in the same manner as the PIDxxxA models (refer to Section 6.1). However, for the PIDVxxxA, the intensifier is integrated into a D03 (CETOP 3) ported manifold block. A control valve is required and must be mounted above the intensifier in a valve stack on a D03 (CETOP 3) valve manifold.
  • Page 17 6.3 PIDMxxx Models The PIDMxxx models function in the same manner as the PIDxxxA models (refer to Section 6.1). However for the PIDMxxx, the intensifier is integrated into a flange mount manifold block that is designed to face-mount to a custom manifold block.

    7.0 SERVICE Except for a few maintenance oriented items, the PID Series intensifiers contain no user-replaceable parts. Maintaining the proper filtration and flow rate of the inlet oil will help provide trouble-free operation. Service kits containing replacement filters, O-rings and orifices are available from your Enerpac distributor or authorized service center.
