The H1 Pump is selected by using the information H1 Pump's Piston Rod Driverdeveloped while selecting the H2 unit(s). (See calculation The H1 Pump's piston rod travel is critical to the success-pages in the HYDROCAMcatalogue.) See page 4.ful operation of the HYDROCAMsystem.2. Select an H1 Pump that provides the H2 unit's volume 1. Machine smooth and parallel, the tools mountingtotal within 90% of the H1 Pump's total volume.

Properly guiding the tool and cam station will minimizewear to the cylinders and increase seal life. 1. Always use a control panel.2.
