Portable Diaphragm Type Vacuum Pump cum Air Compressor, Oil Free, Light Weight
Product Code : EL-POM-10365
Quick answer: This portable diaphragm vacuum pump cum air compressor is an oil-free, double-stage unit that can draw a low vacuum or deliver low-pressure air, for vacuum demonstrations, filtration and other bench work where oil vapour must be kept away from samples. It is lightweight, runs quietly and comes with cord and plug. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
A diaphragm pump moves air by flexing a membrane, driven by its motor, with valves that let air into and out of the pumping chamber. No oil is used to seal the mechanism, so nothing can creep back into the vessel being evacuated, and glassware and samples stay clean. Two pumping stages in series reach a lower pressure than a single stage of the same size.
Used from its outlet, the same unit works as a small compressor. One pump can therefore evacuate a bell jar or a filter flask for one experiment and then supply low-pressure air for another, which suits a school laboratory that needs both on the same bench.
- Place the pump on a level bench and connect it to the mains with the cord and plug supplied.
- Attach the vessel to be evacuated, or the apparatus to be supplied with air, using suitable tubing.
- Switch on and let the pump run until the required vacuum or pressure is reached.
- Switch off and release the vacuum slowly before disconnecting the tubing.
