Scope of use of pumps for pumping water containing impurities
Pumps for pumping out dirty water are used to drain storage tanks, silted wells, reservoirs, pits, to drain accumulated moisture during a flood. They are also used in case of emergencies when it is necessary to pump out water from a flooded cellar or basement. Drainage pumps are often used on construction sites to drain sediments, groundwater from pits and trenches.
Mud pumps can be safely used to pump liquid from one container to another for the purpose of its further use for irrigation of land. The units are also used for irrigation of greenhouses and vegetable gardens.
Modern mud pumps for pumping water can be used to drain wells from sandy and silt deposits, pumping "blooming" water from open reservoirs, when arranging a drainage system. Due to the special internal structure, the units are able to pass solid particles, fibers and small stones, which makes the devices universal, irreplaceable helpers for performing household tasks.
The selection of a drainage unit should be based on the level of contamination of the liquid to be pumped. Pumps for lightly contaminated water are designed to transport liquids with suspensions of 5 mm. Their productivity reaches 80-230 l / min., Head - 5-12 m.Such units are used for water intake from wells, drainage of pools, pumping water from rain reservoirs. This category also includes pumps for pumping water out of aquariums.
To drain drainage wells and storm drains, pumps are used to pump medium-contaminated liquid with particles up to 25 mm in size, their capacity is 40-450 l / min., Head is 5-22 m. Pumps for dirty water are capable of pumping liquid with suspensions with a diameter of 38-40 mm. The productivity of such units is 50-600 l / min.
Drainage pumps are not used to pump waste water. For this, fecal units are used, equipped with special grinders for large debris, which affects the rise in the unit's cost.
Design features of the drainage pump for dirty water
Vacuum pumps for pumping water are made in a metal or plastic case, which provides mobility and ease of use. Plastic is more sensitive to working with solid particles, therefore, it is characterized by a shorter period of operation.
The pumping unit and the motor are located inside the housing. The working elements of the latter are the rotor, stator and end shields. The impeller, called the impeller, is mounted on the rotor shaft. Both elements are made of stainless steel. The impeller shaft can be located on the engine itself or separately from it. The pump unit is equipped with an intake pipe with holes, the diameter of which corresponds to the size of the solid particles that the unit can pass.
Helpful advice! If the pump for pumping water from a pool, basement or cellar is rarely used, the hoses should be rigid, and if often, then it is better to use flexible pipes.
In order for all the driving mechanisms of the pumping unit to work smoothly and safely, the unit is equipped with a thermostat to turn off the device if the engine heats up to a critical state and a float switch that controls the liquid level in the tank and turns off the unit when the minimum value is reached.
How the Dirty Water Sump Pump with Float Works
When the electric motor is turned on, the shaft with the impeller begins to rotate. A vacuum is created in the body of the unit around the rotating blades. Under the influence of vacuum, liquid is sucked into the working chamber and pushed out under the influence of centrifugal force through the outlet hose, which is carried out under the influence of the created pressure.
The pumped-out water simultaneously cools the engine, which eliminates the possibility of overheating of the pump during long-term operation of the unit. However, in this regard, the drainage pumps can pump liquid, the temperature of which does not exceed 50 ° C.
Important! There are special expensive models of drainage pumps that can pump liquid with a temperature above 50 ° C.
The float switch is represented by a set of sensors, which are placed in a polymer sealed housing. An electric switch and steel balls open and close the contacts of the circuit when the float changes its position. There is air inside the box. It, like a float, is always located on the surface, following the water level.
There are new dirty water borehole pumps equipped with aquasensor technology, which is used when pumping liquid from narrow reservoirs where it is not possible to place a float switch. Using such a device, you can set the minimum water level, upon reaching which the device turns off. It can be as small as 5 mm.
Characteristics of surface dirty water pumps
Surface self-priming pumps for dirty water are installed near a reservoir or container with water. The pump housing must be on a flat, dry surface. The unit is equipped with two hoses. A suction pipe made of PVC is lowered into the liquid, it serves for its intake from the source. The hose must be strong and resistant to deformation. The outlet pressure pipeline ensures the discharge of water outside the structure.
The surface pump can work in automatic mode. For this, the float mechanism of the pump unit is connected to a toggle switch, which is triggered when the minimum water level in the tank is reached.
The main advantages of surface pumps for pumping water are simplicity of design, ease of installation and disassembly, low demand for labor-intensive maintenance, efficiency and durability of operation. The device has compact dimensions, so it is easy to move, transport and store. Due to the fact that the pump body is not located in water, surface units are characterized by a low level of wear of the mechanism elements.
Important! A surface drainage pump is ideal for seasonal use.
Such a pump works quite quietly, especially for a device in a plastic case. The metal unit hums during operation. To reduce the noise level, it is recommended to place the pump on a platform with a rubberized mat. Surface pumps are characterized by an affordable cost, which depends on the specific model and manufacturer.
It should be remembered that surface aggregates cannot be used to raise water from a considerable depth. The maximum suction head is 8-12 m. The further the unit is located from the water intake, the less its suction capacity. For this purpose, it should be placed as close as possible to the source.
Important! If the pump unit is connected to a sewer network, it is necessary to know the exact diameter of the pipe, since the connection made by using a pipe must be tight.
Drainage submersible pump for dirty water with integrated float
The farm is in great demand, according to numerous reviews, a submersible pump for dirty water. The unit is designed to be located directly in the water column. It can be completely immersed in the liquid or partially peep out of it. Water intake from the source is carried out directly by the pumping unit without involving the suction pipeline.
The suction valves can be located on the top or bottom of the unit body. The first version of the devices is more durable, since this arrangement minimizes the risk of damage to the working chamber as a result of the ingress of large particles. For reliable operation, the second type of devices should be placed on a special stand. There is a mesh filter on the bottom of the unit, which protects the internal structural elements from the effects of large solid particles and debris.
It is advisable to use a submersible unit if it is necessary to pump out dirty water from a considerable depth of up to 50 m.Such a pump should not be used for shallow reservoirs and ponds less than 20 m deep. This is due to the fact that during the operation of the device, the engine is constantly cooled due to the fact that the pump is immersed in water for a long period.
Important! If it is necessary to use a submersible pump for drawing water from a shallow source, it is necessary to arrange additional cooling of the electric motor with water.
The installation depth of the device is determined by the type of tank. It should be borne in mind that the lower the pump is lowered, the more efficient its operation.
The main advantages of submersible drainage pumps are the high power and performance of the units in comparison with surface analogs, the ability to take water and completely drain deep wells and tanks, resistance to temperature extremes, to the effects of aggressive substances that may be present in dirty water. As noted in numerous reviews, submersible dirty water pumps operate almost silently without creating vibrations.
The main disadvantage of a submersible pump is the need to remove it for maintenance and repair. Organized body tightness complicates the process of performing scheduled preventive work.
Submersible pump for dirty water: features of the operation of the unit
Submersible electric pumps for dirty water work constantly in automatic mode, which is carried out due to the presence of a float mechanism, which is connected to the power switch. It turns off the electric motor when the minimum water level in the structure is reached. Thanks to this operating mode, the pump can be permanently installed in a sump or well. It will periodically turn on when the tank is full.
Important! Adequate protection of the automation and sealing of the electric motor must be provided for the pump, since the unit will constantly work under water.
Submersible pumps for pumping water must be made of corrosion-resistant materials that can withstand significant mechanical stress and damage. The nodal elements can be made of polymers, engineering plastics, alloyed, carbon steel, electrical alloy, which is determined by the purpose and nature of the perceived loads.
In expensive submersible pumping units, oil seals are used to seal the electric motor, which are made of ceramic cups, or an oil lock is used for connection.
Classification of drainage pumps by purpose
Drainage pumps can be divided into two categories depending on the area of use. These are units for household and industrial use. The first group includes devices that are used for household needs. These are pumps for pumping water from a pool, for draining technical rooms, wells and tanks, for irrigating land from a source or reservoir.
Important! A drain pump can be used to operate a small fountain.
Drainage pumping units for domestic needs are represented by single-phase low-power pumps with a capacity of 800 l / min and a working head of 25 m. Such pumps are made of reinforced polymer or stainless steel. They can handle contaminated liquids with impurities up to 10 mm.
The second group includes surface or submersible industrial pumps for dirty water, which are characterized by increased power and performance.With the help of such units, it is possible to pump out sewer tanks and clogged pipelines, drain industrial drains, eliminate emergency flooding, drain the collector and pits during construction work.
Industrial drainage pumps are equipped with electric motors that are housed in cast iron cases. The powerful radiator ensures efficient heat dissipation from the engine, and the cast-iron housing protects it from deformation during strong heat generation.
Industrial pumps are represented by three-phase units with a capacity of 1500 l / min, which can transfer liquid to a height of up to 150 m. Models are characterized by a complex design, therefore, they need to involve a specialist to maintain the equipment.
Feature of hand pump for pumping water
A hand pump for pumping dirty water from a tank or container outside the structure is similar in principle to an electrical unit. The main differences lie in the design features of the device and the speed of its operation, which depends on the quality of the efforts applied.
Hand pumps for pumping water are made in three types - piston, vane and hose units. The first option is presented in the form of a cylinder equipped with a piston. An opening valve is located inside, and a disc valve is located at the bottom of the cylinder.
When making translational movements in the cylinder, an airless space is created, which ensures the supply of water. It is supplied under pressure to the cylinder and is discharged through the drain pipe when the bypass valve is opened. Such a pump is used to pump out dirty water from shallow springs up to 7.5 m deep.
A hose pump pump for pumping water is designed similarly to a piston pump, except for a longer piston and cylinder length, which creates a more powerful vacuum, which contributes to raising water from a considerable depth - up to 28 m. Instead of a rod, a pair of rods is used, connected by a special hinge.
The vane hand unit has a long handle, which is equipped with a rotary pump. When making rotational movements, fluid is sucked in and transferred through the overflow hole. To operate such a pump, you will need a garden elastic hose. The unit is quite compact, so it is easy and convenient to carry it to a new place.
How to choose the right drain pump for pumping water
There are several simple guidelines for choosing a drainage pump for pumping water from a basement, well, cellar, pool or other object. The area of use is considered first. For this, a surface or submersible type of pump unit is selected. Equally important is the maximum lowering depth of the pump unit, which is different for each model. Consideration should also be given to the purity level of the liquid to be pumped, since each model operates with a specific viscosity.
Important! For home use, it is better to consider submersible models that can be used regularly at any time of the year.
For reliable and durable operation, it is worth giving preference to a pumping unit that is equipped with protection against overheating, automatic shutdown of the electric motor at the moment the minimum permissible water level is reached and a filter to prevent large debris from entering the housing, which will negatively affect the efficiency and service life of the unit.
Important! When choosing a submersible pump for dirty water, the price of which is lower than the cost of a surface-type device, it is necessary to be guided by the maximum temperature threshold of the transported medium.
The next important criterion is the performance of the pumping device, which determines the amount of liquid that the unit can pump per unit of time. The larger this value, the faster the working process takes place. However, this entails an increase in electricity consumption. To remove water from the basement or drain the cellar, a unit with a capacity of 180 l / min is enough.
Another important parameter is the working head, which indicates the ability of the device to push the liquid to a certain height. For the calculation, the ratio of 1 m vertically to 10 m horizontally is taken.
When choosing a submersible unit for household needs, you should focus on the location of the suction inlet. If it is necessary to completely drain the bottom of the structure, it is better to purchase a model for pumping water from the basement or cellar, in which the suction hole is at the bottom.
When choosing a unit, one should take into account the rating of leading manufacturers and popular models that have won recognition in the market. Consumer reviews about a particular pump will help to determine the choice.
