LaserCraft 91-413, 2x Hand lever pump 1:87

A handle pump is a self-priming water pump. Handle pumps are simple piston pumps, the piston of which is operated by hand using a two-armed lever called a handle. The piston is connected directly to the shorter arm of the handle via a piston rod and is usually sealed with a leather sleeve.

This pump design is simple and independent of the power grid and water supply. It is used around the world for wells for water supply and often in allotments. Due to its properties, it is used in places for water supply in an emergency if the network fails.Evidence for the existence of this type of construction and functionality is already 300 years old. With this pumping system using the law of levers, those wells were replaced in which the water was brought up from an open shaft with the bucket hanging on the rope. With each pull on the rope, the full weight of the water (five to ten kilograms) was pulled directly. Alternatives to this were draw wells that had a swinging boom with a counterweight.

As long as there were no water networks, handle pumps were practical for pumping groundwater and were widely used. Up to the beginning of the 20th century, handle pumps were used for pumping on streets (public street pumps) or as court fountains in front of the house or in the courtyard. Around 1920 handle pumps were still installed in the house in such a way that they were in the kitchen. While aqueducts gained in importance in cities, handle pumps were still widespread in rural areas until well into the 1950s. Copies are still available and active for certain uses.
