Open Center Systems— All Models
Adjusting Centrifugal Pump Output
Refer to Section 3.5.2 of this manual before adjusting the pump.
Consult the instructions included with the Open Centre Tractor Hydraulic Kit before making any adjustments.
Select the motor size closest to tractor’s hydraulic system capacity. Regulate oil flow with Spray Pump Flow
Control. Completely close the motor NEEDLE VALVE. (Do not use restrictor orifices.)
Note: Before installing a new Hypro sprayer pump, check the inlet port of the hydraulic motor to see if a restrictor
orifice has been installed at the factory. To check this, remove the pressure port adapter from the motor and
look inside it. If the restrictor has been installed, remove it by popping it back out of the adapter.
1 . Shut off the sprayer boom electric ball valves, the thottling valve and agitation valve.
2. Open all pump supply valves ensuring there is water at the pump inlet.
3. Start the tractor and activate the hydraulic circuit.
4. Turn ‘ON’ the electrical switch that controls the selector valve.
5. Set the tractor throttle to the sprayer operating
speed.
6. Adjust the flow control valve until the sprayer shutoff
pressure is just below the maximum shown in the
SHUTOFF PRESSURE section on the page 58.
7. Open the sprayer throttle and agitation valve to get
the desired agitation flow.
8. Fully close the electric regulating valve.
9. Turn the electric ball valves on and adjust the flow
control valve to have 30 psi more pressure at the
spray tips than will be used when spraying in the
field.
