The men owning a private cottage quite often should solve a problem of pumping out of dirty water independently, but the choice of special pumps in shops is quite big and to buy a reliable and inexpensive thing not and simply. Therefore let's understand how to choose model of the drainage pump for dirty water and what technical parameters of the device are most important.
How to choose the drainage pump - we define device type
For a start it is necessary to be defined what problems this device has to solve. Pumps of drainage type can quite popustit through a hose various grains of sand and pebbles, but, only if the size of these particles does not exceed 5 cm, otherwise the hose will get littered. There is also the second type of devices which are calculated on pumping of waters with excrements and long particles, for example, threads or hair. Similar pumps are called fecal. If you need to extort water from the cellar, or a reservoir, the first type of the device - garden will approach if you look for the pump for the sewerage, it is worth getting the fecal device.
How to choose the garden drainage pump for giving?
It is possible to find the submersible unit and the superficial pump of this kind in shops. What type of the drainage garden pump to choose, depends on features of the forthcoming work. The superficial device differs in rather low price, it easily can be mounted independently, but it not too powerful therefore it should be taken only if depth where it will work, does not exceed 5 meters. One more feature of this type of the device is what will need to be covered in its winter as at low temperatures it can fail, especially, if it is necessary to use it at this time for designated purpose.
The submersible device is more expensive, but at the same time it is suitable for pumping of very polluted water in which there are particles from 2 to 5 cm in size. Upon purchase of this device, pay attention to arrangement of an opening for water absorption. Those models in which it is below can pump out almost completely water, unlike other designs. The pump having function of automatic shutdown otherwise will be the most convenient it is necessary to keep track independently of water level at its pumping and to stop the device manually. Submersible devices differ from each other on power, for pumping of water from the cellar or watering of a kitchen garden will be to buy enough model which is capable to pump out 100 liters of water in 1 minute.
How to choose the drainage pump for the sewerage?
Fecal pumps are very similar to submersible garden devices, but their power and capacity of a hose will be 10 times more. Upon purchase of this unit it is necessary to estimate how many liters a minute the device can miss through itself, it is considered that the good device has to have an indicator not less than 120 l in 60 seconds. It is not less important to look what size of fraction can pass a hose, the this parameter is higher, the device model is better and more reliable.
Now let's understand what drainage pump to choose for a septic tank if there is no electricity. All devices mentioned above work, as a rule, from an electrical network when there is no electric power on the site, it is necessary only to get a manual pomp. At its choice it is necessary to watch what size of fraction passes a hose. It is the only parameter which really deserves attention, all other characteristics of the device it is possible not to consider especially as they will affect speed operation of the device and its safety and reliability a little.
