How to choose fecal pump - pump types , user selectable

viscous fluid with a high concentration of solid and fibrous inclusions are characteristic of certain types of waste views industries, agriculture, and housing and communal services sphere.The pumping of liquids of this kind is only possible when using a fecal pump.It is used for draining basements of houses, pumping wastewater and sewage, cleaning of cesspools and wells.Its main difference from other types of pumps, a larger diameter channels, high reliability, ability to work in a chemically aggressive environment.Often fecal pump inlet mounted shredder that turns too large and long fiber fraction in the inclusion of a smaller size.Depending on the pump design and the method of installation sewage pumps are divided into:

• submersible;
• semisubmersible;
• exterior.

fecal submersible pump

This pump is a monoblock, which is completely immersed in the liquid medium and is mounted on the bottom.This type of pump has a high efficiency at a relatively low price, so it is widely used both in industry and in the private sector.At a power of 40 kW pump can lift 400 cubic meters of liquid per hour and at 20 meter height

Due to the fact that the pump is located below the level of pumped liquid cooling its engine is made of the same liquid, which imposes a restriction on its temperature - not more than 40degrees Celsius.It also leads to the need for protection of the engine from the work "dry".Automatic pump shutdown when the minimum level of the liquid by means of the float switch.

semisubmersible fecal pump

Mounting submersible models produced on a special float.As a result, the submerged pump is only a part.The engine is out of the liquid medium, which facilitates the execution of maintenance work.And the use of air cooling enables to work with fluids at temperatures above 40 degrees - the restriction is usually set at around 100 degrees Celsius.

compared to submersible models submersible pumps the flow channels have a smaller diameter, and the pumps themselves are not equipped with macerator.This imposes a limitation on the scope of this type of sewage pumps.Their use in common the need to remove waste liquid.

External fecal pumps

This is the least efficient and most inexpensive form of sewage pumps.His body never interacts with the fluid, therefore is made of cheaper materials than the housing of the submersible pump.The liquid drops only the suction pipe and the pump itself is installed near the work area.

Typically, these pumps are used when necessary mobility.If the use of a stationary pump supposed to protect it from environmental factors, it must be installed indoors.In situations where suitable premises near the work area is not available, under the pump can be equipped with sump or caisson.

drain pump

Submersible pumps can be used for pumping liquids with low levels of pollution: clean pools, reducing the groundwater level, drainage of stormwater.They are often used in irrigation and irrigation systems.Submersible pumps can be submerged or external, but the latter are much more frequent.In order to automate drainage pumps typically implemented dim when it reaches a certain level of liquid and trip reduction of this level.This mode of operation allows for autonomous operation of the pump to avoid a "dry run" of the engine and thus reduce the cost of maintenance and repair.

drain pump works by the centrifugal force produced by rotation of the impeller and the ejection liquid through the outlet channel.The impellers can be channel or vortex.

vortex impellers create a fluid rotation that takes place outside of the wheel.

Due to this they can work with the environment, in which there are long fibrous structures.If fluid is present a large amount of sand, the use of vortex impellers will also be a good solution.

channel impeller directly affect them passing through the liquid flow.

to the free movement of solids in such wheels are provided channels.Depending on the amount of their share of one-, two- and multi-channel impellers.Efficiency pumps with multi-channel impeller is 85%, but the long fibers and sand slurry can quickly disable them.

systems forced canalization

If the level of water entering the sewer system, is below the level of the central sewage system, or the distance from the source of sewage to the main riser so great that Gravity evacuation of sewagedoes not occur, the system uses forced canalization.The system is a fecal pump with macerator equipped with storage capacity.It fills gradually, and when it reaches a certain volume automatically switched cutting mechanism and the pump.Large particles are crushed and sewage delivered to a central sewer system.

Such systems differ depending on whether the temperature of the cutting device and the pumped fluid.Independent of water temperature devices with macerator are significantly more expensive than usual.Therefore, for the treatment of waste water shower, washing machine and dishwasher it makes sense to install a pump without a grinder, designed to work with hot and relatively clean water.A toilet sewage must pass through a shredder device;high-temperature requirements, in this case will be charged.
