High Pressure Food Grade (H1) Lubricant
Due to the high forces inside the intensifier all bolts and cap screws that fasten the load carrying
components are
Grade 8 . Fasteners that are exposed to cyclic loading use lock washers. Torque the load
carrying fasteners to the correct Torque Specifications unless otherwise noted.
Keep all interior parts and surfaces clean. All parts should be placed on clean
work surfaces. When changing HP components such as HP seals, hands should
be washed and kept clean. Before reassembling any high pressure or hydraulic
components, verify that the components have been wiped clean to remove any
dirt or other contaminants.
7.3 High-Pressure Ends
High-Pressure Seal Replacement
Replacing the high-pressure seals and hoops is the most common service function. Water dripping from
either end of the HP cylinder indicates that the seals may soon require changing. One drip every few
strokes means that the seals should be watched. More than one drip with each stroke means that the
seals in that HP cylinder should be changed at the first opportunity.
This section will provide the basic information needed do in-house replacements and service on the
high-pressure ends for the HyPrecision 100D/150D pumps. For any questions and all other service
needs please contact 0.15"service representative.
The high-pressure end drawing shows the locations of the components and their part numbers. Always
check the part list included with this manual for the latest parts and their replacement part numbers.
