How to choose the best submersible pumps

For septic tank, swimming pool or irrigation

It is necessary to know the type of environment in which the pump will operate in order to make a decision about which pump to purchase. To understand how to choose a good submersible pump, rather than paying attention to the price, first concentrate on your specific needs, this will help you to set the search parameters in the area that interests you. This is the most important thing to know about home water treatment systems. If you don’t know the difference between black water, gray water and clear water models, you won’t know what type of home water treatment system will serve your needs the best. Efficiency and reliability are some of the other factors that influence the choice of a specific model.

Black waters and gray waters

In sewage collection pits, septic tanks, pools, or other submerged applications where debris may tend to block the pump, it is the best choice for a submersible pump. This type of pump has a larger diameter impeller which allows it to operate properly even with solid particles that would normally cause other pumps to malfunction In addition to the costs, the type and size of the motors are important factors in determining the purchase decision. The lifting capacity of the pumps is up to 5 meters, and they can be purchased with a price range of 70 to 100 dollars. The types of pumps used for these applications are usually the submersible type.

Clear waters

Submersible pumps are the most common type of pump used in irrigation systems. They’re mainly used in artesian wells, where they have a reduced diameter and have a greater lifting power. Depending on the situation, this can reach up to 90 meters. The price of these models is roughly the same as that of the black water pumps. The only exceptions are those submersibles intended for ornamental purposes, such as aquariums and fountain pens, which are characterized by a decidedly low cost.

Frequent questions

How does the submersible pump work?

A submersible pump is a device that is used to lift water from a tank or well and bring it to a higher altitude so that it can be drained or diverted to a piping system. Submersible pumps are usually used for draining swimming pools, tanks, and other areas prone to flooding, such as basements, underpasses, and underground passages. It’s an operating principle that is simple: the pump is driven by a motor whose switch is connected to a float, once placed in the well or in the place where its use is required, the presence of water causes the float to rise up to operate the switch. In the case of black or gray water treatment, the impellers also have the additional function of facilitating the flow of water, as the engine starts up and a flange begins to suck in the water pushing it towards them. When the water level gets low, the float drops, which causes the pump to stop.

How to check a submersible pump?

It is a good idea to have a back-up system in place in case your main power source fails. It’s important to know how to operate and maintain your back-up power supply. Since the pump may have been subjected to some damage or even theft, it is necessary to replace the components, so the first thing the pump should be examined for is its structure. Theubmersible pumps are used to fill the tank with water. Submersible pumps can be used if there is not enough pressure to force the water out of the tank. There are many situations in which the submersible pump can assist. It is easy to repair and it is much safer to use than a manual pump.

How to use a submersible pump

The installation of pumps for artesian wells varies depending on the type of pump and the place where it will be installed; in fact, pumps for artesian wells must simply be lowered to the required depth, after which the pipes must be connected to the relative water system that In the case of pumps that are installed in drainage shafts or inside tanks, the connection fittings must be prepared in advance and the exhaust pipe fixed to the valve fitting and held in place simply by the use of a metal gasket. The thread on the pump delivery must be covered with Teflon in order to avoid leaks, because the pump has an angle fitting that needs to be mounted on the delivery. Once the main fitting has been fixed to the delivery, it is a good idea to put a non-return valve on the drain pipe in order to prevent the water from coming back up when the pump is turned off. On the other hand, the exhaust pipe is fixed to the valve fitting and held in place by the use of a metal piece. The non-return valve needs to have the same diameter as the fitting and the drain pipe. The valve fitting needs to be covered with Teflon in order to ensure perfect seal, and it needs to be equipped with further connections to connect it to the pump and the drain pipe. The exhaust pipe is fixed to the valve fitting and held in place simply by the use of a metal clamp.

How to unblock a submersible pump

If the pump doesn’t start, the motor might be malfunctioning. If the water does not drain, the problem could be caused by a problem in the drainage system, so if you want to be certain that there is nothing wrong with your installation, it is better to call a specialized technician directly. If you don’t have experience, you should go for the assistance of a technician, as there is a risk of causing damage to the pump and its contacts, if you attempt to disassemble it without the proper knowledge.
