Fuel Transfer Pump (Optional) - Doosan DX140R Operation & Maintenance Manual

FUEL TRANSFER PUMP
(OPTIONAL)
IMPORTANT
Dry operating fuel pump for more than fifteen seconds can
cause wear and/or damage to pump.
• Cooling and lubrication of pump is achieved by fuel
passing through pump. If pump is dry operated, heat
generated by moving parts will cause damage to pump
rotors, vanes and seals.
Do not operate pump for more than fifteen minutes at a
time.
• Continuous usage of pump over recommended time
interval will cause overheating of motor and will result
in causing motor damage.
Do not use refueling pump for other types of fuel or fluids.
(Use only for diesel fuel.)
• Do not use refueling pump for other types of fuel
which have a low flash point.
• Do not use refueling pump for fuel contaminated with
water or high humidity. Moisture in pump mechanism
can cause rust and can create pump failure.
Always operate pump using strainer installed on inlet hose.
This will prevent any foreign materials from being
introduced into pump. Always maintain pump and all of its
components in a clean condition.
• If dirt or other foreign materials enter pump, it can
become lodged between the rotor and/or vanes and
generate heat which can cause pump damage.
• Do not remove strainer or use a strainer with larger
mesh to increase flow of fuel.
Be careful not to overfill or spill fuel.
Make sure direction of check valve is in line with flow
direction of fuel.
If any pump parts or components become lost, damaged or
inoperable, immediately replace it with a new ones.
