This pump has been designed and
constructed solely to pump agricultural
liquid chemicals, normally used for pest,
weed and fungus control.
Must Not Be Used To Pump:
· Liquids with a density and viscosity greater
than water.
· Chemical products if the compatibility with
the materials of the pump is not known.
· Sea water or other salty concentrations.
· Water with a temperature above 40°C and
less than 5°C.
· Any type of varnish.
· Solvents and thinners for any type of
varnish.
· Any type of fuel or lubricant.
· Liquids containing granules or floating solid
parts.
· Chlorine.
· For special liquids please contact Silvan
service department.
Pre-Operational Checks:
1.
Check the oil level while the pump is
standing still and sitting horizontally. The
oil must reach the level indicated on the
sight glass (fig 1). Top up with SAE
20W/50 oil if necessary.
Figure 1 Figure 2
2.
Adjust the air pressure in the pressure
accumulator if fitted (fig 2) in
accordance with the operating pressure
used to spray. Adjust according to Table
A. The pressure can be measured using a
car tyre pressure gauge.

Start Up:
1. Ensure the control valve is in the bypass
position and any taps not being used are
in the closed position. Turning the bypass
lever in the clockwise direction will place
it in the bypass position. Repeat this
procedure each time the pump has been
emptied of liquid i.e. Run dry.
2. Bring the pump to operating speed.
3. Switch off the bypass and bring the pump
to operating pressure for the application
using the pressure regulator.
4. Check the oil level during the first hours of
operation and top up if necessary.
Shutdown:
Flush the pump after use by running clean
water for a few minutes
If there is a risk of freezing run the pump dry
for a few minutes to remove all liquid from
the pump
