📄𝗧𝗿𝗮𝗻𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
This is a hand pump. It’s also called well pump, deep well pump, pitcher pump and parish pump. When you move the handle up and down, you eventually get water from the outlet pipe.

The design of the hand pump is quite simple. It has a main body, piston rod , piston, two check valves, handle, and water discharge pipe. When you move the handle up from the down position, the piston rod, piston and first check valve move down. As the second check valve is closed during this movement, air is compressed in the pipe and this causes the first check valve to open. Thus, the air in the pipe is sent to the upper part of the pipe. As the handle moves down from the up position, the first check valve closes . Suction occurs in the pipe and the second check valve opens. Thus, the water in the reserve starts to rise in the pipe. With the movement of the handle, the air in the pipe is completely discharged and the water rises slowly. With the continuation of the movement, the water finally reaches the outlet pipe.

This type of water pump has a range of about 7 meters. If the water reserve is deeper than 7 meters, the suction is not effective enough. In these cases different types of water pumps can be used.

Water pumps are cheap, effective and safe. They are still used in many countries. Have you ever used one?
