__NOTOC__
The name PVC pumps covers a large number of different hand pump designs, which have in common that most parts are constructed out of PVC. PVC is used because it is often cheap, and easy to work with. As PVC is less durable as other materials such as steel, a singe single PVC pump should be used by a limited number of people. Because of the low price, PVC pumps are often used as family pumps. Sometimes other types of Plastic are used, such as ABS, which is UV resistant.
There are many types of PVC pumps, differing in design aspects such as direct action versus lever operated, piston rod versus piston pipe, single or double action, with or without a water seal. The valve designs vary from ball valves, rubber flap/butterfly valves and bicycle inner tube valves to bolt valves, pvc adapter valves, and washer valves.
