3815Y1 SureFire PumpRight for Raven RCM

Revised 12/04/2019
PumpRight Hydraulic Connections
Hydraulic Hose
SureFire recommends
1/2”
hydraulic hose for both pump inlet and outlet. The hoses
will need #8 JIC female swivel fittings.
Where do I get hydraulic flow for my PumpRight?
This question is often asked as many implements use up all the hydraulic connections on a tractor. SureFire
has some recommendations as to what works best.
Best Option
-
Dedicated PumpRight Circuit
If you have a tractor remote available, attach the tractor remote valve
directly to the PumpRight pressure and return ports. DO NOT try to avoid this method
simply to save another set of hydraulic hoses running to the tractor. Operating the PumpRight on it
’
s
own circuit is the simplest for installation and operation. It guarantees the PumpRight won
’
t negatively affect
any other hydraulic components on your equipment.
Alternate Option
-
In Series with John Deere CCS Fan or Bulk Fill Seed Fan
If you do not have a tractor remote valve available, this may be your best method. You can plumb the
PumpRight after the seed distribution fan in series. If using this method, the SureFire PWM bypass valve
must be open (see previous page for instruction & picture). If bypass is left closed, the SureFire valve will
limit the speed of the seed distribution fan.
For example, the John Deere CCS fan uses around 7 GPM of oil. This will limit the PumpRight maximum
flow (9 GPM oil necessary for maximum flow). See the charts on the next page for adjusted maximum pump
flow. See section G for flow charts to determine your necessary flow rate.
DO NOT plumb the PumpRight in series with a vacuum fan. The vacuum fan uses just a few GPM of oil.
Also, problems will be caused by excessive pressure at the vacuum fan motor
Two PumpRights
The preferred method is to plumb the two pumps in series. DO NOT plumb two pumps after the CCS fan.
Excessive pressures may damage the CCS fan motor. Run the pressure line from tractor to first pump inlet.
Plumb from the outlet of Pump 1 to the Inlet of Pump 2, then from Pump 2 outlet back to the tractor. Open
the bypass needle valve on both pumps so each valve controls motor speed independently. Run the flow
setting procedure on the next page to minimize the hydraulic flow based on the pump that requires more
hydraulic motor flow.
E
Installation
Overview
Hydraulic oil under extremely high pressure. Do not use
hand or any other skin to check for or to stop hydraulic
leaks. Be sure pressure is relieved before loosening
hydraulic fittings. Replace worn hoses immediately. Seek
medical care immediately if hydraulic oil is shot into the eye
or the skin.
