396-3815Y1 SureFire PumpRight for Raven RCM 39 Revised 12/04/2019
PumpRight Hydraulic Oil Flow Requirements
(Requirements for 4.0 CID Motor—standard SureFire motor beginning in 2016—
Earlier motor was 4.9 CID which uses 20% more oil)
Setting Tractor Hydraulic Remote Speed
PumpRight pumps require a constant hydraulic oil flow from
the tractor. The amount of oil needed varies with pump size
and speed. The chart at right shows the necessary oil flow for
each pump model at varying fertilizer flows.
Use this procedure to determine the correct setting on your
tractor hydraulic flow.
1. Run the fertilizer system in the field at the maximum rate
and ground speed.
2. Turn down the hydraulic flow slowly while watching the
pump flow (Volume / Minute).
3. Observe when the Volume / Minute begins to drop.
4. Turn the hydraulic flow back up slightly.
This setting will provide the Pump Right pump just enough oil
for your application rate.
If running with the bypass open (only recommended when 2
motors are operated in series) this process will minimize the oil
circulated in the bypass loop, leaving more oil flow for other
hydraulic functions.
The pump is rated at a maximum of 550 RPM. Spinning the
pump over 550 RPM may cause pump failure.
The system will spin the pump faster than that if precautions
are not taken to limit the speed. This could happen if the
strainer becomes plugged or blocked and the controller
attempts to speed the pump up to achieve the desired Rate.
It could also happen if a high pressure situation occurs that
opens the Pressure Relief Valve (PRV) and the pump speeds
up to try to achieve the Rate.
Monitor the pump RPM. If the pump begins to speed up, check
for a blocked strainer or other issue.
Set the Pump RPM High Limit and Maximum Pressure Alarm
as shown in Section F.
Another way to limit the maximum pump speed is to set the
High PWM Limit just above what is needed for regular
operation. If the pump tries to speed up above that, check for
blocked strainer or other issue.
