Sump Pump how to choose and install
Deprived urban water supply and private owners of country houses and cottages are often used as a source of well water. Surface pumps can supply it only in the case of small depth of the well and its small distance. If the depth is greater than 8 feet , then come to the aid sump pump , which are submersible equipment . Variety of types of pumps for wells , and we dedicate this article .
Classification Sump Pump
All sump pump on the market to customers’ attention can be classified according to several characteristics :
surface pumps ;
pumping stations .
The method of lifting water .
The pressure generated in the system ( the height to which the water rises ) .
The quality of the fluid :
clean water ;
slightly contaminated water ;
dirty water .
Pump power .
The purchaser gets a challenge of choice. Much needed in the cottages and private homes mechanisms – Sump Pump : how to choose , what to choose ?
This type of pump is a cylinder made of stainless steel, inside of which there are:
centrifugal motor is hermetically sealed ;
impeller to the outdoors water.
So there was a constant cooling submersible pump , it should always be in the water below the border. In order to prevent accidental pumping out all the water from the well, there are different devices that signal the critical point of water:
Floats – frog ;
electronic automatic system.
The most reliable in operation is the well pump with a float , as it is such a device is simpler and much more durable than other designs.
Sump Pump Reviews: How to Choose a Sump Pump
The advantages of this type of pump includes:
Depth: up to a few tens of meters.
Excessive head – the height to which the water rises : up to 60 m
High performance: up to 3.5 cubic meters per hour.
The main disadvantage is the possibility of a submersible pump spill oil used for cooling and lubrication. Improper use or failure of the pump can cause depressurization chamber , in which the oil. In this case, will require quite expensive works as an oil film on the surface of water is difficult to remove .
Another shortcoming is that the connection is well pump requires installation of home electric line that provides its power .
Submersible drainage pumps
This type of pump is used:
for rapid evacuation of large volumes of water ;
for professional cleaning of wells.
Obvious advantages of these pumps can be:
Ability to pump as clean water and heavily soiled .
High performance (up to several tens of cubic meters per hour).
Float protection from drying , allowing the use of these sump pump with automation in the sewer and drainage systems.
The disadvantages are :
Small head .
Low height of water – up to 10 m
Loss of use of the water system to avoid clogging her suspended particles due to undemanding these pumps for water quality .
Vibration submersible sump pump is mainly used by vacationers as “seasonal” , the device supply house and land because of their obvious advantages :
ease of use ;
high pressure : up to 60 m;
affordable price .
The disadvantages include:
low productivity ;
they can not be used in wells arranged on quicksand .
Vibrating water pumps Pit working in wells on quicksand can activate it . As a result, the bottom rises in the sump water volume decreases . These processes will inevitably lead to the need for more frequent cleaning of the well.
Installation of submersible pump
Installation of all submersible pump runs on a single technology , is simple to implement and is as follows:
Mounting the pump itself is carried out using a dense rope that is pulled through the holes featured on the cover.
The pump is lowered into the well (it is desirable to maintain it with the hook) . The distance to the bottom should be more than 30 cm
When installing important to make sure that the pump does not touch the walls of the well.
As you can see , the installation process is really very simple . It should be noted that the low quality of groundwater preference is given to the models equipped with a floating filter.
The surface-type pumps
Characterization of surface pumps
” Pros ” of surface pumps:
Large head .
High reliability due to the fact that the pump is immersed directly in the water.
Big performance .
Easy operation and maintenance
The continuous mode of operation.
The ability to use the clean and dirty water .
” Cons ” of surface pumps:
Small suction lift : up to 9 m
Reduction in system reliability by using an ejector helps to raise the height of the absorption of water up to 20 meters
Noisy operation , requiring that the well pump installation was done in a separate equipment room .
The need to have skills to fill the suction pipe with water and its use.
Produced by some manufacturers pumping stations include all the elements that are needed to operate the water system and its management in automatic mode:
These devices need only connect to the water system.
On the market there are pumps that can suck water alone . They do not require special water filling the suction line . Water is poured into a special cavity in the pump casing and it is ready for operation. Mostly these pumps are used for periodic , brief work.
Installation of pump surface type
Surface pumps are well suited for use in areas with a fairly shallow groundwater. Well pump installation should be carried out as follows:
The suction pipe is hermetically connected to the pump.
Lower the end of the line that has a check valve in the water.
Pour in the water line .
Avoid any air pockets , water leaks in the suction pipe , preventing the pump from working.
These pumps are often used as the second stage at a sufficiently deep well, which leads to increased water pressure in the system. The first step in this case – submersible or centrifugal pump .
