Note: These are general guidelines and do not cover all possible situations. It is the responsibility
of the system integrator to apply this product properly.
Hydraulic Motor Orientation Considerations
• The G125 is a hydraulic driven gear pump and is not
intended for use with a driveline. (See pg 11 for hydraulic
trunk specifications)
• Hydraulic motor orientation must be checked prior to
operation to ensure the correct pump rotation for the
internal relief valve. (Fig. 1 & Fig. 3)
• Refer to Manufacturer’s owners manual for specifications
regarding the hydraulic motors. Ensure the hydraulic relief
valve setting does not exceed the hydraulic motor limitations.
Hydraulic Hoses & Fitting Considerations
•
DO NOT use thread tape or pipe dope on threaded connections, this will contaminate
the hydraulic system. Use a hydraulic sealant (Locktite number 545 or similar) as
required.
• Hydraulic hoses are customer supplied, and will need to be measured to fit per
application. Pre-plan hydraulic hose routing to minimize sharp bend radii, avoid surface
contact, and to allow for flex during operation.
• High pressure hoses must have a pressure rating equal or higher than the hydraulic
system relief valve setting.
• Hydraulic Hoses must be supported and not allowed to hang or pull on equipment
Piping Considerations
• Inlet pipe should be as large in diameter, short in length, and straight as possible to
minimize suction pressure losses. Excessive restrictions at the inlet can cause
cavitation, resulting in poor performance, noise, vibration, or pump damage.
• Slope the inlet plumbing appropriately to avoid air pockets.
• Plumbing weight, misalignment with the ports, or thermal expansion can exert
excessive force on the pump. Plumbing must be properly supported and aligned with
expansion joints, if required, to minimize these forces.
• To prevent over pressure situations, install a relief valve as close to the pump outlet as
possible. Install the relief valve before any shut-off valves.
