Jetmatic hand pump parts from the Philippines like Dragon, Champion, and other brands are the components used in a hand-operated water pump system that is widely used in rural areas where there is no electricity or consistent water supply. The main parts of a Jetmatic hand pump system include: 1. Pump cylinder: This is the main part of the pump, usually made of PVC or brass, and is used to lift water from the ground. 2. Handle: The handle is used to operate the pump by manually pushing and pulling it up and down. 3. Foot valve: The foot valve is located at the bottom of the cylinder and is responsible for stopping the water from flowing back into the ground. 4. Connecting rod: The connecting rod is located inside the pump and is connected to the piston inside the cylinder. The up-and-down motion of the handle transfers the power to the connecting rod, which moves the piston. 5. Piston: The piston is responsible for drawing water up to the surface by creating suction and pushing it up through the pipes. 6. Pipe fittings: Pipe fittings connect the pump system to a piping system that delivers water to the storage tank or directly to the house. The Jetmatic hand pump system is an affordable and sustainable option for accessing water in rural communities. It can be used for drinking, washing, and irrigation. The system is easy to maintain and repair, making it a reliable source of water for generations.
