Safety Notice
Warnings
NOTICE
WARNING: Warning Instructions listed on this page must be reviewed by ALL operators.
Safety instruction tags were attached to your unit prior to shipment. DO NOT remove, paint over or obscure in any
manner. Failure to heed these warnings could result in serious bodily injury to the personnel operating and maintaining
this equipment.
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.

Mounting Considerations
•Mount the unit on a rigid, heavy base to provide support and absorb shock. The base
should be designed for rigidity across a flat even surface.
•Mounting kits are available with directional control valve mounting and ball valve
mounting. (Fig. 2)
•Positioning the product pump lower to the ground will assist with suction conditions and
decrease the risk of cavitation.
Initial Installation Considerations / Continued

Over-pressure may burst
pump or system components. !
Always include a relief valve
in installation. Do not over
pressurize pump or block
discharge line while running.
Pre-Operation Checks
•Ensure hydraulic motor mating surfaces are clean and free from debris
•Check hydraulic motor rotation.(Fig. 1)
•All hydraulic hoses are installed according to manufacturer specifications and supported
properly.
•G125 Pump mounting feet are flat against the mounting surface.
•Ensure the Relief Valve is closest to the discharge port for protected operation.
NOTE: While in reverse operation, the discharge circuit will be unprotected, possible over-
pressurization can occur.
•G125 relief valve is adjusted appropriately (100 psi from factory, +/- ~5 psi per full turn).
•All piping is securely mounted and supported.
•Check to ensure the pump will turn.
NOTE: The G125 pump must be rotated at least once a week for 3 seconds, use of a lubricating
oil (WD-40) is recommended if the pump is not going to be put in use.

Relief Valve Adjustment
Factory Relief Valve Settings for the G125
The Factory Setting for the Chemical Pump Relief valve is as follows
Determine Pressure limits for G125
Identify Spec # located on the ID Plate of G125 at the bottom left corner, the last 2 digits
identify the pressure limits of the Relief Valve Spring 1A or 1B as shown in picture below.
Spring Limits:
1A = 20-80 PSI
1B = 81-125 PSI
Note: Pressure should NOT be set below or above the limits of the spring shown.
CAUTION: DO NOT adjust the pressure rating or tamper with the chemical pump while it is in operation.
Setting the G125 Pump Relief Valve (Fig. 4)
1. Loosen locknut (item 2).
Note: Each full turn on the adjustment screw is approximately a 5 psi change in relief pressure.
•To increase the pressure setting - turn Adjusting Screw (item 1) clockwise.
•To decrease the pressure setting - turn Adjusting Screw (item 1) counterclockwise.
2. Re-tighten locknut. (item 2)!
