Lift Pump
Product Code : LSK-POM-11204
Lift Pump (SKU LSK-POM-11204) is a glass working model of a cylinder and piston fitted with non-return float valves and a side outlet tube, used to show how a lift pump raises water as the piston moves up and down. It serves secondary school science and introductory college physics. Science Lab Supplies manufactures the model at its Plot 448 unit in the HSIIDC Industrial Area, Saha, Ambala, India, and quotes it from the factory to schools, colleges, tender contractors and distributors.
Specifications
The glass lift pump model's specifications are tabulated below. In short, it is a glass cylinder with a piston and non-return float valves, plus a side tube through which the lifted water flows out, so that every stage of the pumping cycle can be watched by the class.

Applications and Experiments for the Lift Pump
With the lower end in water, raising the piston lowers the pressure below it, so atmospheric pressure pushes water up through a float valve; on the down stroke the valves change over and the water passes above the piston, leaving by the side tube. The glass body makes this cycle visible.
- Secondary physics: explaining how atmospheric pressure lifts water in a hand pump and why such pumps have a height limit, with air pressure read on an Aneroid Barometer.
- Comparing it with the Force Pump, whose secondary cylinder ejects water through a jet.
- Engineering foundation and TVET courses: introducing positive displacement pumps before work on the Piston Pump module.
Handle the glass model gently, move the piston slowly and support the cylinder securely over a water vessel.
Standard Scope of Supply
The model is supplied as described above: the glass cylinder with its piston, the non-return float valves and the side outlet tube. A water vessel, stand and clamp are not included, though a stand or beaker can be added to the same quotation for a ready demonstration.
Packing, MOQ and Lead Time
Ask for a quotation for one model for demonstration or several for group work. Science Lab Supplies details the packing, delivery time and price for the quantity requested, with the packing of the glass model stated on the quotation, and the companion force pump can be priced on it too.

Frequently Asked Questions
How does the Lift Pump model work?
Raising the piston lowers the pressure in the glass cylinder, so atmospheric pressure pushes water up through a non-return float valve. Further strokes carry the water above the piston until it flows out of the side tube.
What is the difference between a lift pump and a force pump?
A lift pump raises water and lets it flow out of a side outlet. The Force Pump model adds a secondary cylinder with its own non-return float valve and ejects water through a jet at high pressure.
Why is the model made of glass?
A glass body lets students see the piston, the float valves opening and closing, and the water moving up the cylinder, which is hard to show with an opaque metal pump.
Is Science Lab Supplies the manufacturer of the Lift Pump?
Yes. The model is manufactured at the Science Lab Supplies facility in Saha, Ambala, India, and the company quotes it to buyers itself, as the factory responsible for building it.
