Rexroth Solution:

Custom-configured GoPak hydraulic power unit

Results:

  • Rexroth recommended a GoPak hydraulic power unit custom-configured to meet the Pampanito’s requirements
  • Bosch Rexroth worked with its distributor partner Hydraulic Controls, Inc. and volunteers from Manson Construction Co. (who are also submarine veterans) to develop the GoPak’s specifications
  • The unit includes a 71 cc Rexroth A10VSO axial piston pump driven by a 15 HP motor, providing a 30 GPM flow and supplying a maximum working pressure of 750 psi
  • The GoPak unit provides an easier-to-operate and more efficient replacement of a legacy “air over hydraulics” system for supplying hydraulic power
  • Visitors to the Pampanito can now see the periscope being raised and lowered, the torpedo tube doors open and close, and the bow planes operate just as they did during the ship’s service
  • Hydraulic Controls, Inc. supplied the GoPak unit as a donation to the non-profit San Francisco Maritime National Park Association, which owns and operates the Pampanito
