⚙ drain pump for dirty water: types and characteristics

If flooded basement or it is necessary to drain the small pond, Drainage pump for dirty water to cope with the task. Equipment to work effectively, it is necessary to choose the right type and to deal with the technical specifications. We offer to meet with the existing species and their characteristics.

Applications drainage pumps the dirty water

Pumps can be used for pumping different liquids. impurities depends on the size of the design features of a particular model. The required information is usually contained in the accompanying documentation. Depending on the size of particles occurring in the water, devices are divided into three groups:

• less than 5 mm. Used to malozagryaznennoy or clean water;
• to 25 mm. It allows to pump liquid soiled;
• 25 - 38 mm. Provide pumping melt, rain or other contaminated water.

Besides impurities geometrical parameters, one should consider their chemical composition and temperature of the fluid. Aggressive environment can cause premature equipment failure. Avoid this allows the correct choice of the model, the details of which are made of materials suitable for use in such conditions.

Such equipment is used for drying:

• flooded basements;
• storage wells;
• filled pools;
• land after heavy rainfall.

Design and operation of the drainage pumps the dirty water

Operational characteristics and position of the drain pump depends on its construction. That in the process of pumping the dirty water no difficulty, offer to get acquainted with their distinctive features of a particular type pumps. This allows you to choose a model with a good performance.

surface

Similar devices are installed on the edge of the tank or reservoir with dirty water. Fence content via the branch pipe is lowered onto the tank bottom. the remaining fluid level is controlled by a float mechanism. As soon as the float reaches a predetermined level, the system will automatically shut down. Due to this, the surface device can operate in stand-alone mode, without human intervention.

Self-priming devices have a compact size. Easily transported to the new location, do not make high demands for service. Given that during the operation, such deposits are located on the surface, it greatly simplifies the repair and maintenance works. May be part alluvial stations connectable to wells or wells.

Submersible

Such devices are completely immersed in the pumped liquid. They do not like suction surface models. Fence dirty water through the holes provided in the bottom of the unit. To protect from falling into the drain pump large solid impurities provided strainer. The housing apparatus has sufficient strength and impermeability to prevent liquid from flowing into the evacuated structure.

Submersible models can operate in automatic mode. Turning equipment occurs only after accumulating a sufficient volume of liquid. To ensure the stability and security of the device operation provides enhanced electrical insulation. They have more power and performance. Durable, quiet.

Main characteristics of drainage pumps the dirty water

The main parameters that characterize extraneous equipmentThey are:

• performance;
• pressure. If you have to draining a deep basement, this figure could be major;
• evacuated medium;
• climatic conditions in which the equipment can be operated.

marking

Marking pumping equipment depends on the manufacturer. For blade models most often as the main indicator used material blades. The division is made on a model in which the data elements are made of stainless steel cheaper and more expensive and durable technopolymer.

Leading Russian and foreign manufacturers

When choosing a drain pump for dirty water should pay attention to the products of companies that are interested in the high quality of the delivered equipment. These manufacturers include:

• "JEELEX". Russian manufacturer offers pumps, adapted to Russian realities. A wide service network allows for timely recover the equipment and carry out its maintenance;
• Pedrollo. Italian company offers various types of drainage pumps;
• Karcher. For German products are characterized by high build quality;
• PATRIOT. US different equipment availability and high performance;
• gnome. Domestic drainage pumps, designed for home and professional purposes;
• "BELAMOS". Russian-Chinese manufacturer produces equipment that meets all modern requirements;
• «GRUNDFOS». Danish brand has its own production in Russia.

How to choose a sump pump for dirty water: tips and tricks

When choosing a sump pump should take into account many factors that determine the service life and performance of the equipment. We offer to meet the criteria, deserves special attention.

Performance and pressure

For drainage equipment performance is one of the important criteria. It determines the quantity of dirty water passes through is applied for one hour. Find the information you need can be a passport supplied with the device.

Ask a Question

«Performance affects the time it takes to pump a certain volume of liquid. "

Required parameter depends on the purpose of purchase. If the drain pump is purchased for use in the home, 10 m³ / h is sufficient. For professional use worth buying equipment with a capacity of 100 m³ / h.

The pressure varies within the range of 5 - 50 m and determines how high the water can rise. This figure is dependent on the type of dewatering equipment and is associated with the distance that the removed liquid. The latter index refers to the pressure as a 10 to 1.

Attention! For domestic use enough pressure exceeding the settlement 3 m.

The diameter of output nozzles

An important parameter that affects the performance of the equipment. The diameter of the outlet connections should be selected with great care. The parameter depends on the degree of water pollution. For the usual liquid enough 0.5-1.5 inches. Dirty - more than 8.

When selecting a suitable type should note that the connections are vertical and horizontal connections. The pump should be connected to a hose having exactly the same diameter.

Attention! Ask what the liquid level remains after pumping.

By material manufacturing parts and housings

The materials used for the manufacture of pumping equipment parts, determine its lifespan. The housing may be metal or plastic. Models of plastic have a lower cost, but are afraid of mechanical action, often deform and crack. Recover such equipment is almost impossible.

Pumps in a metal casing can withstand a considerable load. They have a long service life. stainless steel or iron may be used for their manufacture. Such materials allow operation in all conditions.

Special attention is given material blades. This may be a polymer or stainless steel. With a choice preferred embodiment is a polymer. Special additives improve wear resistance material. Metal wear out faster, but also cheaper.

According to additional features

When choosing a model, make sure you have a circuit breaker. He will launch the device as soon as the liquid in the tank reaches a certain level. Circuit breakers can be:

• electronic. Part of the pump, increasing its cost;
• float. Reliable and inexpensive assembly having a relatively simple constructive design.

Also need to be concerned about the presence of protection against overheating and a strainer on the inlet to the device.

Recommendations for operation and maintenance

The equipment has served long enough, you should:

• carry manufacturer's recommendations indicated in the accompanying documentation;
• refuse pumping dirty water with particles whose dimensions exceed the recommended by the manufacturer;
• a differential device connected via machine;
• disconnecting the device when moving it from place to place;
• refuse to pumping corrosive, explosive or flammable liquids.

Extends the life of drainage pumps for dirty water: general guidelines

The service life depends on the design features of a particular model. To prevent premature equipment failure, to avoid overheating the motor. This can be achieved, primarily, by choosing the drain pump dirty water with suitable characteristics. It should not be shortened float "leash". This will increase the number of motor starts, and the motor winding overheating failure.

Also help avoid overheating installation thermal relay. Such a node will monitor the degree of heating the engine and disconnect it upon reaching a critical value.
