Hello, Science enthusiasts, today I am going to tell you about the hand pumps. These are used to extract the water present in the earth to the top of the earth. These are mostly used in remote places. If you like this article you should subscribe to our Email and PUSH notifications service for free.

Nowadays bore wells are becoming common to every house. Generally, we use motors to pump the water from underground to earth surface. But the bore wells which are dig in the public places they won’t use motors, for their use they fit the hand pumps.

As we discussed that motors will work with electrical energy but the hand pumps will work by man power. If we move the handle up and down then it’s a magic the water will come from the delivering tube which is arranged at bottom of handle or opposite side of the handle.

This handle is also known as the force rod. These hand pumps are like a long cylindrical tube with a handle, piston, check valve, water outlet tube, water suction line, sealing O-ring and main, water is important at the bottom of that hand pump.

Do you think how this is actually possible and are you interested in knowing the science behind this physical activity? Don’t worry, I am here to make you learn how it happens so.

Here’s the answer that how the hand pumps works:

hand pumps internal construction and workingWhen the piston moves downwards in the hand pump, the foot valve closes to prevent the flow of water and piston valve opens to allow the piston to move down through the water in the cycle and when we push the piston upwards, the piston valve closes and a partial vacuum is created below the piston valve.

This causes water to be drawn into the cylinders. In a suction, hand pump water flows outward through the delivery outlet. This is the working principle of the hand pump.
