Surface pump for dirty water is convenient and sometimes necessary equipment for a private house. Such a technique there is always an application, it is only important to choose exactly the model or a universal multifunctional unit.
A feature of such pumping pumps is their installation on the surface (as opposed to submersible, directly in the pumped medium) of products. In the liquid at the surface pump, only the hose or the input nozzle is immersed.
Scope of application
Unlike models of pumps intended for lifting and transporting on pure water pipelines, Pump for contaminated liquids not afraid of solid and soft insoluble inclusions . Nevertheless, the capabilities of the models are different - if some are capable of pumping water with sludge, then others are able to cope even with thick viscous compositions, in fact, with liquid mud. This moment must be found in the selection stage, given the intended scope of the pump.In a private house or at the cottage, the pump superficial centrifugal for dirty water can be used for:
- Drainage of basement or cellars during a flood or when an emergency occurrence,
- pumping fluid from viewing wells,
- drainage of accumulative or drainage datals and holes,
- drainage of pools, fountains, artificial reservoirs, if necessary cleaning, repair, or before the occurrence of winter,
- The supply of partially purified or groundwater from the pit or drainage yams (wells), storm drives for watering plants,
- Irrigation system devices using a natural reservoir,
- Drainage of the kittlers in the construction of a house or surplus buildings, if groundwater is high on the site.
Types of pumps
When choosing a pump model, it is important to remember that the surface pump for dirty water, the price of which seemed to you attractive, should have certain capabilities. Evaluating the alleged operating conditions and the tasks set, compare them with the characteristics of the model. In order for the variety of the range easier to navigate, you should know characteristic of certain categories features.
- Centrifugal pumps Capably pumping fluids with a high content of impurities provided that the maximum linear size of the inclusion particles does not exceed 10 mm. To ensure the durability of pumps, it is important that the transported medium is not chemically aggressive with respect to the elements of the feeding equipment device. The most popular are products of this category of console monoblock type.

- Drainage self-priming pumps They are distinguished by high power and wider compared to other product features. Such aggregates are also capable of pumping fluid with insoluble inclusions up to 10 mm, however, drainage machines allow a higher content of impurities, as well as the possibility of transporting liquids with solid inclusions (similar models are called slim). The advantage of pumps of this category is a wide range of operating temperatures (from -10 ° C to + 90 ° C, depending on the model). Self-priming design allows you to lift fluid to a height of up to 9 meters.
- Screw models Pumps are capable of pumping viscous strongly polluted fluids, as well as strokes with sufficiently large inclusions. Therefore, such designs have fecal pumps for dirty water. If there is a reservoir on the site or next to it, even a small and very dirty, the screw surface pump will allow the use of fertile silt to fertilize the beds. The pumps of this category are capable of transporting fluids with a temperature to + 75 ° C.
- Membrane self-priming The products allow presence in pumped water to 50% insoluble particles with a linear up to 50 mm. With this technique, you can dry the channels and trenches, since in such cases there may be not only sand and clay impurities in water, but also small stones, whiskers of the land, etc.
Surface pump for dirty water pumping may be stationary or mobile . In the first case, the design is advisable to choose for permanent or often use. For example, when using stormwaterflaws or water from a water branch for watering, it is better to mount the technique at the place, than to transport it there every time.
The surface self-priming drainage pump WILO can be installed inpatient or used as a portable device.
Mobile pump models can be portable (possess a small power) or equipped wheels on the principle of the cart (with high technical characteristics). They are chosen for periodic use, for example, in emergency cases, to drain the pool, which is required no more than several times a year, etc.
Features of surface pumps for polluted water
Any surface self-priming pump for dirty water has both advantages and disadvantages, so it is important to comprehensively assess the models when choosing.The advantages of pumping aggregates of this type include:
- Unpretentiousness and ease of operation, thanks to which the technique can be easily transported and installed almost at any desired place. Sufficient conditions are only the presence of a flat site and the possibility of connecting to the power grid.
- High values of the main operating parameters of the pumps, including the height of the lift and pressure required for horizontal transportation through the pipeline.
- The increased wear resistance of the main nodes and parts, due to the need to cope with large loads, and also in contact with solid inclusions in dirty water, which can have abrasive properties.
- The ability of pumps to long-term operation without technological breaks.
- Lower, in comparison with submersible units, cost.
Minuses of surface pumps - this is:
- The impossibility of lifting water from the bottom of deep wells, trenches or water bodies (as a rule, the height of the lifting of models of this type does not exceed 8 m).
- High noise when working (constantly or often working in the house or near the windows on the site Pumps. placed in soundproofed booths To ensure comfort).
- The need to accurately perform instructions when installing the suction hose or nozzle due to the high probability of an accident in case of violations. If the home owner does not have the necessary experience, it is better to use the help of a professional.
Operating Rules
Despite the multifunctionality of all pumps of this type, one should inquire the possibility of using them for transporting clean water. It may seem that the pump capable of pumping the dirty liquid is able to cope with clean, however, in most cases, the design features of the machines do not allow such an opportunity (for example, due to too wide inlet).

There are other rules that will ensure the durability and trouble-free operation of the surface pump:
- Models of any type cannot be immersed in water.
- Connecting to a power source should be carried out through a safety vehicle, which will prevent the failure of the pumping unit at voltage jumps.
- Be sure to comply with the operating conditions of the pump in relation to the composition of the liquid (the percentage of impurities, their maximum permissible size, chemical aggressiveness of the medium, fluid temperature, abrasiveness of inclusions).
- It is impossible to transport (including moving, tilt, swing) working pump.
- With year-round use of the pump, it is important to take care of thermal insulation and system heating to avoid freezing.
The Council for the choice of pump
To determine the required technical characteristics, you can use some rules:- Performance It is easily calculated by dividing the volume of the pumped liquid (for example, the pool in the garden) for the time during which this volume should be moved (dumped). More productive pumps have a higher power.
- Estimate Pressure characteristics It will be easier if you consider that each meter of lifting corresponds to 10 meters of transportation of the liquid horizontally. Thus, despite the partial justice of the statement that the pressure should be the less less than the depth of the reservoir or the reservoir, the calculation is to include and the need to move the pumped fluid to a certain distance.
Popular models and prices
The following pumping units should be attributed to the most popular and practical and functional models of pumps:
Pedrollo surface pump
- Pedrollo NGA. From the famous Italian manufacturer - pumps intended for installation indoors and under sheds. Machines are capable of working at outer temperatures up to -10 ° C, while the temperature range of the pumped liquid is from -10 ° C to + 90 ° C. A constructive feature is the presence of an open impeller, thanks to which the pump is capable of pumping a strongly contaminated liquid. The stainless steel wheel is resistant to corrosion and abrasive effects of solid particles. The features of operation should include the need to fill the system with water through a special hole before starting. Price of pumps 17.2-17.6 thousand rubles.
- Cars Calpeda C. Also have Italian origin. They have proven themselves as reliable and unpretentious pumps intended for pumping liquids with an average impurity content (linear size - up to 4 mm). Depending on the performance of the characteristics, the cost of 14.6 thousand rubles may have (power - 0.15 kW) to 28.8 thousand rubles. (1.1 kW).
