Commissioning Start-Up, Operation, Shutdown

Before Starting the Pump:
Secure the outlet lines before starting the pump. An unsecured line may whip, causing personal injury and/or
property damage.
Check hose for weak or worn condition before each use. Make certain that all connections are tightly secured.
The sound pressure level of the pump is 80 dBA. Observe all safety precautions when operating the pump within close
proximity for extended periods of time by wearing hearing protectors. Extended exposure to elevated sound levels will
result in permanent loss of hearing acuteness, tinnitus, tiredness, stress, and other effects such as loss of balance and
awareness.
Start-Up and Operation:
Open Center Systems - All Models
Adjusting Centrifugal Pump Output
1. Start the tractor. Leave the directional valve in the neutral position and allow hydraulic oil to circulate for approximately
10 to 15 minutes or until adequately warmed.
2. Prime the centrifugal pump with all valves open (See the Installation Instructions and System Configuration Diagram).
3. Close the agitation line valve and keep the control valve and the boom shut-off valve open. Note the spray pressure.
4. Open the agitation line valve until you have desired circulation in the tank. Recheck the spray pressure. If it is too low,
close down the agitation line valve until the desired spray pressure is reached. If the spray pressure is too high, throttle
the centrifugal pump by closing down the control valve.
Closed Center (Load Sensing) - All Models
Many tractors are being introduced with load sensing systems (also referred to as flow and pressure- compensated systems)
which simplify system setup and eliminate many of the problems associated with using the wrong size pump motors on a giv-
en hydraulic system. Usually, any of Hypro's 9300HMC models may be used on this type of system, provided the hydraulic
system produces sufficient oil flow for the hydraulic motor being used (Refer to the Pump Selection Guide).
This system maintains a constant flow of hydraulic oil for a given pressure drop. The flow is adjustable with a flow control
valve installed in the hydraulic system (such as the Tortoise/Hare control on John Deere tractors). Because this system has
adjustable flow, there is no need to bypass hydraulic oil as in an open center system, or to restrict the flow with orifices as in
a closed center pressure- compensated system.
Adjusting Centrifugal Pump Output
1. Set the tractor hydraulic flow control valve for minimum hydraulic oil flow to the remote outlet (Tortoise position).
2. Start the tractor and allow the hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.
3. Prime the centrifugal pump with all valves open (See the Installation Instructions and System Configuration Diagram).
4. Close the agitation line valve and open the control valve and the boom shut-off valve.
5. Slowly adjust the tractor hydraulic flow control valve until the desired boom pressure is attained.
6. Open the agitation line valve until sufficient agitation is observed. If spray pressure drops, readjust the tractor hydraulic
flow control valve to restore it to the desired pressure.
Cleaning and Shutdown:
Flush Pump After Use
One of the most common causes for faulty pump performance is gumming or corrosion inside the pump. Flush the pump and
entire system with a solution that will chemically neutralize the liquid pumped. Mix this solution according to the manufactur-
er's directions. This will dissolve most residue remaining in the pump, leaving the inside of the pump clean for the next use.
To Prevent Corrosion
After cleaning the pump as directed above, flush it with a permanent-type automobile antifreeze (Prestone
containing a rust inhibitor. Use a 50% solution, half antifreeze and half water, or fill the pump with FLUID FILM
drain it. A protective coating of FLUID FILM
next application. Plug the ports to keep out air during storage. For short periods of idleness, noncorrosive liquids may be left
in the pump, but air must be kept out. Plug the ports or the seal port connections.
