Hand pumps serve as the heart of the entire system of suburban water supply. That is why it is worth considering their main characteristics.

In the case where there is no electricity, manual waterThe pump for cottages is the only option. It weighs about 20-25 kilograms and is relatively inexpensive. Its operation is based on the principle of a jack or a well of a well. Of course, physical effort can not be dispensed with, but they are much less than what is required to carry water from a well in buckets. Hand pumps can produce 25-40 liters per minute, depending on how often the effort is applied. Relatively inexpensive models can raise water from a depth of not more than 7 meters. More expensive specimens will allow you to work with sources whose depth is 15-30 meters.
If we are talking about a pond whose depth is notexceeds 7-9 meters, it is quite appropriate to use a surface pump. It is not located in the water, only the hose for its fence is placed there. Such devices are relatively inexpensive, small, have a small weight and a simple device, many models do not require any complicated maintenance. Surface pumps can be centrifugal and vortex. The former are able to extract water from greater depths than the latter, but they are not able to work in shallow water bodies. Vortex pumps are capable of giving a pressure of 2-4 times more with the same impeller diameter. They are much more compact, therefore several times cheaper than similar centrifugal models.
A hand garden pump should be chosen carefully enough, because this device will serve a long time, so it should be of high quality.
