1) Main Technique Data：
2) Features:
FL-3 Pneumatic Explosion-proof Sump Pumps Suitable to empty ballast tanks, bilge wells, water, coal mine etc., in emergency cases. Often used for draining cargo holds during and after the washing procedure. Especially preferred where an electric spark may risk ignition or explosion. Require air pressure is 0.5-0.7Mpa . Special safety control cell could auto-stopping, when over loading. Because of the diameter of the outlet for water discharge is larger than common, the water or oil discharge could reach ≥60m3/h.
3) Operation Instructions ：
1． Air consumption mast be at least 3 m3/h. It match 5-7kgf air compressor.
2． Before using, make sure to the pneumatic valve opening state , cleaning the air hose, Smoothing the air motor with motor oil (20#). Checking the inlet and outlet if right fasten..
3． Putting the sump pump in water, opening the air controller, starting it.
4． It could control the water discharge by the adjust air supply.
5． When finishing, Shutting the air supply valve, dragging for the pump, Let is pump free loading 15 second with Low pressure air, discharge the leaving in the hose.
4) Maintaining Point:
1． When free loading,，make sure the air pressure between 0.1Mpa and 0.5Mpa, Over 30 second be forbidden..
2． Make sure the air hose inside part cleaning before connection with the pumps.
3． To let working capability more efficiency, it’s better control the air pressure between 0.5Mpa and 0.7Mpa
4． To prolonging the working life, we suggest checking the pumps 8000-1000 hour a cycle.
5． We strong recommend smoothing the pump before or after using , motor oil(20#) is workable.
6． The air motor is free servicing half of year, pumps body is free servicing a year, both are counted from the buying date.
5) Ordinary Solutions for Failures

Failures
|
Reasons
|
Solutions
|
|
When the pump run abnormity or not workable
|
Air-motor sheet were grinded terribly
|
1. Not enough oil supply
2.There are some
impurities in air
supply
3. It has been used for a long time
|
Inspect oil-supply system and compressor gas-supply system, and replace the sheet with a new one
|
|
The cover of motor were grinded terribly in front and back
|
1.The bearings have worn and the rotor is slippage
2.Gasket don’t match it
|
Replace the bearing and adjust the gasket
|
|
The stator of motor is not the right state
|
1．Impurities was leaked in the stator, such as sand
2,It has been used for a long time
|
Replace the stator
|
|
The sheet of motor were broken
|
The space for the rotor is too spaciousness
|
Replace the rotor
|
|
|
The output power is inefficient
|
1.Air pressure is low
2.The air hose is too small or accessories is narrow that create the flow cut off or plugged
3.Some problem with the exhaust air hose
|
Check the air pressure (0.5Mpa-0.7Mpa)
Check the lines and accessories to make sure of meeting the technology parameters regulations of the corresponding motor features
