Of 6 kinds of the best submersible pumps: how to choose which one to buy, the pros and cons, features, rating

Submersible pumps used to organize domestic water systems, pumping a large volume of liquid drainage various reservoirs, removal of respective collections of impurities. Such equipment is used for the abstraction of water from almost any source, be it an ordinary or a well as deep well. Properly chosen for specific tasks model provides a high efficiency of the entire system pumping fluid, as is a key link in the chain and has a direct influence on its performance.

How to Choose a submersible pump

Before proceeding to the choice of a particular model immersion pump, Should define the tasks. Based on these, the following equipment is divided into two major types:

• To work with clean water. Pumps are divided into skvazhennye and the Pit, and differ only in size, in principle. Used to organize the clean water supply system for domestic use, including watering plants in home gardens. If you touch only the specifics of the work, the model for the well developed under conditions of constant changes in water level.
• Dirty Water - designed for pumping water with different mechanical impurities, for example from the ground floor, pools. Their subspecies - sewage pumps, designed specifically for the respective operating conditions.

When choosing a submersible model should focus on the following criteria.

Type pump mechanism

By water extraction method submersible pumps can be divided into the following types:

• Vibration - operate on the principle of the piston. Moving in one direction, the membrane pumps the fluid and the reverse - pushes it into the hose. This design is considered to be reliable and durable, vibration models have a low cost. Among the shortcomings should be noted vibration and noise during operation, which may lead to silting of the bottom of the well.
• Centrifugal - used most often it is in suburban farms. They are silent, and the water supply is effected by a rotating impeller. Engine cooling is performed by the pumped liquid. Contacting the body of water is made of stainless steel, it has a Nickel-chrome plating. Most of the centrifugal models sensitive to water quality, because is equipped with a built-in filter.

Performance

The parameter indicates the amount of liquid that is capable of pumping equipment pumped per unit of time. Usually stated in cubic meters / liters per hour. The required performance depends primarily on the task, it must not exceed a so-called production rate. Otherwise not excluded idling, during which the equipment is overheated. To approximately calculate the necessary performance required quantity cranes in the building is multiplied by 500 l / h.

pressure

This option effectively means the height to which the pump is able to lift the water, it is always specified in the specification. However, it should be noted that the equipment will move the water, not only in the vertical portion of the well or wells, but horizontal and home plumbing. To calculate the desired pressure, it is necessary to lay down the depth of the hole and the distance to the most distant user, and then to the result add 10% of the stock.

diameters

If you plan to use the pump in the well, its size, in principle, do not play a special role. When it comes to the well, the model is selected based on its inner diameter. value is also have diameters of connecting tubes which have to match the diameter of the pump outlet.

power consumption

The passport to the pump motor usually indicates its power consumption. Based on the power provided by said connection and capable of withstanding respective load. Typically, power consumption rarely exceeds 2.5 kW, and most models are in the range of 500-1500 watts.

Among other things, attention should be paid to the network cable length extension to increase it if necessary. is also important such characteristic as the minimum water level. It indicates the minimum distance to the bottom, where the performance will be maintained. Important is the presence of various security functions - such as automatic shutdown in case of overheating or dry running protection.

Best submersible pump for well

Model VMtec AQUA VES 3/5 MA a centrifugal mechanism is designed to work with clean water only, even at low temperatures (-5 degrees). Major differences of this pump from the nearest competitors are reliability and simplicity of construction, the ability to work in the contaminated fluid.
