Overview
FQW Mining Pneumatic Submersible Pump
The FQW assembly combines an air motor, pump, lubricator, connectors and muffler for pneumatic mine drainage.
It is intended for drainage at mine faces, roadways and shaft-bottom sumps within the verified medium and compressed-air conditions.
Applications
- Drainage at underground mine faces and roadways.
- Water removal from shaft-bottom sumps where a suitable compressed-air supply is available.
Working principle
Compressed air passes through the lubricator to drive the air motor, which powers the pump section.
Connectors complete the air and discharge paths, while the muffler manages the exhaust connection and is normally kept above water.
Features
- Integrated pneumatic drainage assembly with air motor and pump.
- Lubricator, connectors and muffler included in the documented system arrangement.
- Air consumption is model-specific and must be matched to the available air supply.

Verification before selection
Keep the muffler connection normally above water, maintain the required lubrication and prevent dry running. Confirm model-specific air consumption before selection.
Frequently asked questions
Where is an FQW pump typically applied?
The current manual covers mine faces, roadways and shaft-bottom sumps, subject to the listed medium and air-supply conditions.
Is one air-consumption figure valid for every FQW pump?
No. Air consumption is model-specific and must be checked against the selected model and available compressed-air system.
What operating cautions should be planned?
Provide lubrication, keep the muffler connection normally above water and do not permit dry running.
