Overview of surface (outdoor) pumps

The name of this type of pump speaks for itself. The main difference between the design and submersible is the absence of a sealed protective case. The engine is air cooled. The principle of operation when creating pressure is identical - vortex or centrifugal. Outdoor pumps are intended only for clean (or slightly contaminated) water. There are practically no domestic models of drainage external pumps - as a rule, these are powerful units installed on the basis of sewage machines or expensive bulky devices.

The pump itself is the basic element of the water supply system. It consists of an impeller located in a closed casing, fixed on an axial shaft. The drive to the shaft can be electric or from an internal combustion engine, but in any case, the operation of the pump begins with the application of a rotational force to the shaft. We will consider two of the most popular types of these devices: electric pumps and motor pumps.

The main advantage of the external design of the device can be immediately mentioned. It is definitely maintainability. Free access to the engine and components makes monitoring and maintenance quick and convenient. You can determine an impending malfunction by noise, evaluate overheating. Quick installation and dismantling of equipment allows you to improve the system without long-term water outages. Regardless of the drive, they can become part of a multi-stage continuous water supply system at home.

Of course, there are disadvantages common to all. This is the noise level and the need for a separate room with a constant temperature not lower than +5 ° C (can be combined with a boiler room). Sometimes the pumps are installed directly in the well caisson.

Electric drive

Device

The simplest of the existing factory pumps (except manual). The electric motor is connected to the impeller chamber via a shaft. The chamber has the same diameter inlet and outlet (typically 1–1.5 in.) Threaded for pipe fittings. Feed - in the center (at the root of the blade), exit - along the edge (at the end of the blade). Sometimes a protective automatics (fuse) is provided. The electric motor can be 2-phase or 3-phase. Any three-phase equipment is, as a rule, an industrial scale and will not participate in our review.

Application area

The people call portable surface electric pumps "garden" and this name justifies itself. Devices in a compact, easy-to-carry design are indispensable in households where there is a possibility of connecting to the network. Where for some reason it is impossible to install appropriate equipment in a well or a well or for temporary water supply (seasonal or during construction). To obtain a jet with a pressure, you only need to connect the hoses, lower the water intake into the source and turn on the pump itself. It takes a few minutes, which means, among other purposes, it can be used as a fire fighting equipment.

Advantages:

  1. Compactness.
  2. Low cost.
  3. Quick installation and start-up (manual models).
  4. Variety of models.
  5. Not afraid of dry running.

Disadvantages:

the need for electricity

* - head - the height to which the pump raises the water when the diameter of the water column is equal to the outlet of the working chamber. 10 meters head = 1 bar operating pressure

** - immersion depth - the distance from the surface on which the pump is located to the water intake

Internal combustion engine (ICE) drive

Device

A pump driven by an internal combustion engine is called a motor pump. It is a self-contained unit equipped with a 4-stroke petrol or diesel engine. The source of rotation is a shaft coupled to the internal combustion engine crankshaft.

Application area

Everywhere. It can be used even where there is electricity. Remote areas, farms, woodlands, expeditions. Mobile fire extinguishing posts. It can become the basis of the water supply system at home. For specific needs, you can select a specific model: for clean water (high-pressure), for dirty water, mud and fecal pumps.

Note. The world leader in the production of small engines is HONDA. Many different companies that produce motor pumps (China, Russia, Ukraine, etc.) complete their products with HONDA motors.

Advantages (compared to an electric drive):

  1. Autonomy, mobility.
  2. High performance (powerful models).

Disadvantages:

  1. High price.
  2. Complex design (due to the presence of internal combustion engines).

According to their functional and design features, motor pumps can be conditionally divided into two categories - high-pressure and mud pumps.

High-pressure motor pumps are designed to pump only clean or slightly contaminated water. The priority of the device is to supply water at the highest possible pressure. This quality plays a decisive role when choosing a stand-alone pump for domestic water supply. Different in power and performance, they have a high head for supply to the upper floors and remote points of analysis of clean water. Ulita (working chamber) usually has a vortex design.

The so-called "mud" pumps are used for drainage and drainage of reservoirs, maintenance of pools, pumping out waste water. These are circulation pumps with robust impellers, overload protection, pollution protection, designed for long-term operation in harsh conditions. The most powerful of them are designed for pumping viscous liquids - oils, oil and even fuel oil. Since the characteristics of liquids can vary greatly, the performance of "mud" pumps is measured "with clean water" (when pumping water without impurities).

Low power motor pumps are mounted on a frame or legs, and have a carrying handle. More powerful and larger models are equipped with a protective frame and an electric starter. The most bulky installations are stationary. Models with mind-boggling performance are included in a set of equipment for ships, city pumping stations, sewage treatment plants and other industrial facilities. In the next article, we will tell you how to use a motor pump and select the necessary additional equipment for water supply to a country house.

In the event that it is not possible or necessary to install an oil or electric water lifting pump, a hand pump will come to the rescue. It will successfully replace the bucket on the well head and can be installed on the well. Such a pump provides a rise of water from 8 meters, gaining 1-1.5 liters per flow. The price of such a device is about 2000 rubles. The portable version will cost about 1200 rubles. Remember that a hand pump will be a lifesaver in extreme situations - with prolonged blackouts or problems with buying fuel.
