Diaphragm Spray Pump - Hydraulic Drive; Centrifugal Spray Pump - Hydraulic Drive - Goldacres Prairie Pro Operator's Manual

Diaphragm pumps can also be driven by a hydraulic
motor which is bolted directly to the front of the
pump.
The oil line to the hydraulic pump is fitted with a
needle valve that regulates oil flow to the pump.
any tractors feature hydraulic oil flow regulation in
the cabin, however this needle valve can be used to
control the flow on tractors that are not fitted with
hydraulic oil flow regulation.
Where the tractor has the capability to regulate
flow from the cabin, it is recommended to close the
needle valve and ad ust the hydraulic oil flow from
the tractor to set the pump running at 400 - 500
rpm. Do not exceed 540 RPM.
SETTING HYDRAULIC PUMP SPEED
On the Raven 4400 series consoles this must be
set up through the data menu. See Chapter 6
'Calibration' for more detailed setup information.

The ARA SP4
multistage pumps specifically designed for agricultural
spraying purposes.
The use of multiple impellers allowed the
development of a pump made with high resistance
tecnopolymers, granting an excellent compatibility
with spray chemicals.
The design allows high working pressure to be
achieved while minimising pump RPM, assuring a
longer lifespan of all components.
CHARACTERISTICS
• igh efficiency low oil flow
• Reduced size
• Flow rate 400 L/min @ 8 BAR - 103 GPM @
120 PSI (4200 RPM)
• Excellent chemical compatibility
SETTING HYDRAULIC PUMP SPEED
The pump speed is set via the tractor based
hydraulic flow controls. A good uality flow control
system should be used such that pump RPM does
not vary significantly with tractor engine RP .

IMPORTANT: Do not run the pump faster than
4200 RPM.
IMPORTANT: Do not run the pump dry. Running
the pump dry will cause pump failure.
IMPORTANT: Do not run the pump in reverse.
Running the pump in reverse will cause pump failure.
A check valve has been placed in the hydraulic lines
to prevent this.
