173:, it consists of a rotating tube or plane (screw) to move a liquid. Unlike the Archimedean screw, it can pump while horizontal. The Archimedean screw must be tilted at an angle. The spiral pump, if fitted with a suitable rotating seal, can deliver water to a greater height than the coil pump, typically 5-10m, above their discharge opening. Its main drawback is that the output is small - an output proportional to the volume of the largest coil being moved each revolution. Despite the emergence of new pumps that operate on other principles, the spiral pump remains an important tool as it can be built and repaired easily at a very low cost. This is possible as all the components can be built from local resources such as sheet metal bent into the desired form with or without machine tools.

121:. Unlike the Archimedean screw, it can run horizontally while the Archimedean screw is tilted at about 30°. The coil pump, if fitted with a suitable rotating seal, can deliver water to a greater height, typically 5-10m, above their discharge opening. Despite the emergence of new pumps that operate on other principles, the coil pump remains an important tool as some of it other benefits are that they can be built and repaired easily at a very low cost.

161:, which is wound into a coil and sealed at the top and back extremities so as to resemble a cylinder. The outer cavity serves as the inlet, while the inner (partial) tube serves as the outlet. A coiled plastic tube will suffice for this arrangement. The outlet pipe is fixed to a water wheel, engine or animal which is capable of rotating the pump quickly. Due to this rotation, water is picked up by the outer cavity and pumped upwards in the hose.

is a low lift pump which is composed of a tube, shaped as a coil and mounted on a rotating axle powered by an engine or an animal capable of turning the axle around rapidly. Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps,

However, as mentioned before, the pump only allows the lifting of water over a small height. This limitation makes it unsuitable for water drainage or irrigation over larger height differences or many other pumping applications besides drainage and irrigation.
