Owners of their yard often face the problem of pumping out contaminated water. Conventional pumps will not cope with this job. Solid fractions will clog in the impeller, or even it can jam. Drainage pumps are used to pump contaminated liquid. Many models even have a solids grinding mechanism. Among summer residents, the karcher drainage pump for dirty water is very popular, although there are also many units from other manufacturers.
The difference between drainage pumps at the installation site
All drainage pumps are divided into two types, depending on where they are installed: above water or immersed in liquid.
Onshore units
Surface type pumps are installed near a well or any other storage device. Only the hose connected to the unit inlet is immersed in the dirty water. To pump out the liquid automatically without human intervention, the pump is equipped with a float and automation. The principle of operation of such a scheme is simple. The float is connected to the contacts through which electricity is supplied to the pump motor. When the water level in the tank is low, the contacts are open and the unit does not work. As the liquid level rises, the float floats up. At this time, the contacts close, electricity is supplied to the engine, and the pump begins to pump out.
Surface pumps are convenient because of their portability. The unit is easy to transfer from one well to another. All main working units are located on the surface, which facilitates easy access for maintenance. Surface pumping equipment is usually produced of medium power. The units can be used in pumping stations for pumping clean water from a well or well.
Submersible units
The name of the pump already suggests that it is designed to be immersed in a liquid. This type of unit does not have a suction connection. Dirty water enters through the holes on the bottom of the pump. The steel mesh filter protects the working mechanism from the penetration of large solid fractions. There are models of submersible pumps equipped with a mechanism for grinding solid fractions. With such a unit, you can pump out a heavily contaminated tank, toilet, artificial reservoir.
The submersible drainage pump operates in the same way as the surface unit - automatically. It turns on when the maximum liquid level is reached, and turns off after pumping out. A feature of the submersible pump is reliable electrical insulation and high power of the electric motor.
Criteria for choosing a good pump
User reviews do not always help to choose a submersible drainage pump for dirty water. People can advise good brands and give useful recommendations, but the unit will have to be chosen independently for certain working conditions.
So, when choosing a drainage pump yourself, you must take into account the following nuances:
- When choosing any type of pump for dirty water, it is important to pay attention to what size of solids it is designed for. It will depend on this whether the unit will be able to pump out dirty water from an artificial reservoir or whether it is enough only to pump out a turbid liquid with impurities of small grains of sand.
- For a submersible pump, an important characteristic is the maximum depth at which it can work.
- When choosing a unit for pumping hot liquid, you need to find out what temperature mode it is designed for.
- Additionally, it does not hurt to pay attention to the maximum pressure of the pumped out liquid, the dimensions of the pump, as well as the material of its manufacture.
When choosing a good pump for pumping out dirty water, experts advise paying less attention to cost and manufacturer. Let it be a domestic or imported unit, the main thing is that it is designed for the specifics of use and copes with the task at hand.

The maximum immersion depth is 3 m. This model of Italian manufacturers is considered the best choice for home use.
Makita PF 1010
The technique of Japanese manufacturers has always taken the leading positions. A pump with a power of 1.1 kW can easily pump out dirty liquid with solid impurities up to 3.5 cm in diameter. The unit body is made of shock-resistant plastic. The submersible model is suitable for pumping contaminated water from a basement, pond or any pit.
Gilex
The submersible pump of a domestic manufacturer is reliable and affordable. The powerful unit works at a depth of 8 m, is equipped with an overheating system and a float switch. The permissible size of solids in dirty water is 4 cm.
Alko
Alko submersible pumps have a large flow capacity. The most popular is the 11001 model, which can pump 200 liters of dirty water in 1 minute. A big plus is the quiet operation of the electric motor. The durable and lightweight plastic housing made the unit mobile. The pump can be quickly put into operation when the basement is flooded, and, if necessary, moved to another problematic place.
PATRIOT F 400
Ideal submersible model for suburban use. The small F 400 unit can pump up to 8 m in 1 hour3 water. It is not pretentious about the quality of the liquid, since it copes with solid fractions up to 2 cm in diameter. The maximum immersion depth is 5 m. This is enough to immerse the pump in a well or reservoir. A float is included with the unit.
Pumping equipment Karcher
I would like to dwell on the Karcher pumping equipment in more detail. This brand has long gained popularity in the domestic market. Pumps of any type are distinguished by good power, long service life, economy and compact dimensions.
Karher pumps are divided into three groups according to the specifics of their use:
- The high pressure pump is used for cleaning dirty objects. The units are convenient to use in private plots and dachas when washing cars, garden equipment, etc. Compact pumps are made of a durable composite, resistant to corrosion.
- Drainage models are used to pump out highly contaminated and clean water, as well as other liquids.
- Pressure units are designed to pump out liquid from tanks. Pumps are successfully used for arranging water supply from a well.
A popular drainage pump is the SDP 7000 model. The compact unit is capable of pumping out dirty water with solid impurities up to 2 cm in size. With a maximum submersion of 8 m, it can pump 7 m in 1 hour.3 liquid, while creating a pressure of 6 m. The household model in terms of functionality is able to compete with semi-professional counterparts.
