Fuel Transfer Pump (Optional) - Doosan DX700LC Operation And Maintenance Manual

FUEL TRANSFER PUMP
(OPTIONAL)
Do not dry operate fuel pump for more than fifteen seconds.
• 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.
To prevent unnecessary wear and/or damage to
pump do not dry operate fuel pump for more than
fifteen seconds.
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.
IMPORTANT
If there are any sign of leakage while operating transfer
pump, inspect the following components to prevent any
fires or hazardous fuel spills.
• Check all hoses leading to and from the transfer
pump.
• Check all hose clamps.
• Check transfer pump inlet port.
