Hand Vacuum Pump
Product Code : LSK-PL-10338
Hand Vacuum Pump (SKU LSK-PL-10338) is a lightweight, hand-operated pump that draws 15 cm³ of air per stroke and reaches a maximum vacuum of 50 mmHg. Worked the other way, it can also produce positive gauge pressures up to 2 atm. It suits air-pressure and vacuum demonstrations in school and college labs. The pump is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the factory deals directly with schools, colleges, tender contractors and distributors.
Specifications
Each performance figure of the 15 cm³-per-stroke pump has a row in the table. In short, it is a manual pump for evacuating small vessels or pressurising them: it reaches a maximum vacuum of 50 mmHg, and in pressure mode it builds up to 2 atm gauge for school vacuum and air-pressure experiments.

Applications and Experiments for the Hand Vacuum Pump
The pump can be used wherever air must be removed from, or pushed into, a small closed vessel: showing that sound needs a medium, that water boils at lower pressure, or that the atmosphere exerts force. It is a practical addition to school physics lab equipment in India.
- NCERT Class 8 science, force and pressure: effects of atmospheric pressure.
- Class 9 sound: a bell in an evacuated jar grows fainter as air is removed.
- Class 11 physics, mechanical properties of fluids: pressure and gauge pressure, compared with the syringe-based Boyle's Law Apparatus for the pressure–volume relationship.
- Positive-pressure demonstrations up to 2 atm gauge.
Standard Scope of Supply
The Hand Vacuum Pump is supplied as a single unit as described above. Vessels to evacuate, such as a bell jar with baseplate, and any connecting tubing you need for your own apparatus can be added as separate lines on the same quotation for the laboratory.
Packing, MOQ and Lead Time
Ask for one pump or a set for every practical group; either way, the quotation gives packing, delivery time and price for exactly that quantity. A bell jar or crushing can may be quoted on the same sheet so the whole air-pressure bench arrives together.
With an Importer-Exporter Code on record, Science Lab Supplies can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. For a price on pumps and vessels, message the team from the contact page or drop the items into the enquiry cart; formal bids follow the steps on the lab tender page.
Frequently Asked Questions
How much vacuum does the Hand Vacuum Pump reach?
It reaches a maximum vacuum of 50 mmHg and removes 15 cm³ of air per stroke, so the number of strokes needed depends on the size of the vessel being evacuated.
Can it be used to pressurise as well?
Yes. The pump can produce positive gauge pressures up to 2 atm, which is useful for simple pressure demonstrations as well as vacuum work with the same hand-operated unit.
Is there a motorised alternative?
Yes. The Portable Diaphragm Type Vacuum Pump cum Air Compressor is an oil-free, double-stage diaphragm pump supplied with cord and plug, for low vacuum and low pressure where continuous operation is needed.
Who makes this pump?
The hand pump is a Science Lab Supplies product, made at its own Saha, Ambala plant rather than bought in, so the price and delivery stated on your quotation are set by the factory that builds it.
