Force Pump
Product Code : LSK-POM-11205
Force Pump (SKU LSK-POM-11205) is a glass working model that shows how a force pump drives water out under pressure using two non-return float valves and a fine jet. It suits Class 8–9 science lessons on pressure, Class 11 fluids topics and B.Sc. demonstrations. Science Lab Supplies manufactures the model at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it factory-direct to schools, colleges, tender contractors and distributors.
Specifications
The force pump's glass construction and two-valve layout are set out row by row below. In short, a glass main cylinder with a non-return float valve at its foot feeds, through a low side tube, the lower end of a secondary cylinder that has its own float valve and a delivery tube drawn out into a jet.

Applications and Experiments for the Force Pump
The model is used to show, with water visible through glass, how two one-way valves work in turn so that water is pushed out of a fine jet instead of simply being lifted. It fits Class 8–9 science work on pressure, Class 11 fluid topics and classroom demonstrations of how pumps work.
- Class 8–9 science: pressure in liquids and how pumps raise water, demonstrated next to the Lift Pump, a glass model with a piston and float valves that delivers water through a side tube.
- Class 11 physics: watching the double valve action, with one valve opening as the other closes, and relating it to the force of the jet.
- B.Sc. and diploma lectures: contrasting a valve-type force pump with the water-hammer principle of the Hydraulic Ram Pump.
Work the model over a tray or sink so the jet lands safely, and handle the glass parts with care.
Standard Scope of Supply
Each Force Pump is supplied as the glass model described above: the main glass cylinder with its non-return float valve and side outlet tube, joined to the secondary cylinder with its own float valve and drawn-out jet tube. Any optional accessories are confirmed on the quotation.
Packing, MOQ and Lead Time
Quotations can cover a single model for the demonstration bench or one for every student group. Science Lab Supplies prices the exact quantity you request and states the packing method and delivery time alongside it, and other fluid-pressure apparatus can be added to it.
Because it holds an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. For a price on this school physics lab equipment in India, send a message from the contact page, place the model in the enquiry cart, or turn to the lab tender page when a formal bid is being prepared.
Frequently Asked Questions
What does the Force Pump demonstrate?
It shows how a force pump works: two non-return float valves act in turn, so water in the main glass cylinder is driven through the side tube into the secondary cylinder and leaves its drawn-out tube as a high-pressure jet.
How is a force pump different from a lift pump?
A lift pump raises water to an outlet in its own cylinder, while a force pump drives water onward under pressure. In this model the secondary cylinder, with its own float valve and jet, provides that pressure-delivery stage.
Is Science Lab Supplies the manufacturer or a trader?
The force pump model is made by Science Lab Supplies itself, at its works in Saha, Ambala, India. Because the company manufactures the apparatus rather than reselling it, you deal with the maker and receive the quotation from the factory directly.
