How to use the pump for sewage
If you decide to purchase a sewage pump in a private house, then you should at least learn about its technical capabilities, as well as see various modifications and pricing solutions. If you have knowledge of the first two aspects, this will allow you to make the right choice, both technically and financially, because an expensive thing is not always equivalent to good quality or high technical capabilities.
We offer you a brief overview of some models with their technical characteristics, an explanation of the principle of operation, as well as a visual video in this article.
Pumping sewage
Note. The presence of a drainage pump in the apartment for the kitchen does not mean that it should be used exclusively for sewage. The range of its application is much wider, as it is used for cleaning wells or for ordinary plumbing, only, of course, with the use of various filters.
Pump Overview
The case of EUROAQUA QDS 500 is made of stainless steel and two radially centrifugal wheels and a drive shaft are made of the same material, the kit includes a water level sensor that allows you to work in automatic mode.
The pump has an asynchronous single-phase motor with thermal protection (built into the winding), cooled by the pumped liquid, and a ceramic graphite mechanical seal. The QDS series is intended mainly for the supply of clean water from water bodies of various types, as well as for pumping domestic, waste and rainwater, which does not contain solid impurities, and the price depends on the modification.

The maximum size of the pumped particles, as indicated by the instructions, is not more than 5 mm, and the diameter of the outlet pipe is 40 mm. There is an activation sensor, degree of protection IP 68, cable length 7 m, weight 5.3 kg, working temperature of the processed liquid is not more than 35? C.
AL-KO Drain 7000 Classic can process liquid containing up to 5% solids, and the particle size can reach 30 mm. For this, a submersible pump is available with a brass hose mount with an internal diameter of 41.9 mm, which allows for high performance.
Made in Germany, single-phase AL-KO Drain 7000 Classic operates on 220V mains, power 0.35 kW, maximum performance 7.0 m3/ hour, the maximum pressure of 6 m, there is protection for dry running. The nozzle diameter in inches is 1.25, the maximum immersion depth is up to 5 m, the minimum dewatering limit is 30 mm, and the minimum well size is 450x450x450 mm, the cable length is 10 m and the highest temperature during processing of the liquid is no more than 35?
Sprut V 180F can process liquid containing up to 5% solids, and the particle size can reach 35 mm. For this drainage-fecal pump is available with brass hose attachment and cast iron impeller, which allows for high performance.
The single-phase AL-KO Drain 7000 Classic made in Ukraine with a vertical type of installation operates on 220 V, 50 Hz, power 0.18 kW, maximum performance 8.0 m3/ hour, the maximum pressure of 7 m, there is protection for dry running. Nozzle diameter in inches 2.0, weight 8.5 kg, maximum immersion depth up to 10 m, AL-KO 700 Classic has a cable of 15 m, which allows the use of such pumps for pumping sewers of almost any depth.
The case of the Ebara Right 100M is made of stainless steel and two radially centrifugal wheels and a drive shaft are made of the same material, and the sealing cuff significantly increases the service life. Such a pump with a grinder is used for pumping contaminated water, which contains a certain amount of solid particles, up to 35 mm in size, it can be water bodies, pumping stations, and so on. When buying, you can choose two options for the unit - with and without float relay.
Made in Japan, single-phase asynchronous bipolar Ebara Right 100M with a vertical type of installation operates on 220 V, 50 Hz, power 0.75 kW, maximum performance 18.0 m3/ hour, maximum pressure 10.0 m, there is protection for dry running. The diameter of the nozzle in 1.5 inches, weight 11.5 kg, maximum immersion depth up to 10 m, Ebara Right 100M has a cable of 5 m, the minimum dewatering level is 125 mm, the highest temperature of the liquid is up to 50 ° C.
The body of the Aquario Sand-100 is made of cold-rolled electrical steel (AISI 304) and two radially centrifugal wheels and a drive shaft are made of the same material, and the double sealing cuff significantly increases the service life.
Such a sewage pump is used for the kitchen, pumping polluted water, which contains a certain amount of solid particles, up to 5 mm in size, such as water bodies, pumping stations, and so on. In addition, the design features of the hydraulics and the impeller allow pumping fluid containing up to 10% of sand.
Made in Italy, single-phase asynchronous bipolar Aquario Sand-100 with a vertical type of installation (see photo above) operates on 220 V, 50 Hz, power 0.75 kW, maximum performance 16.8 m3/ hour, the maximum pressure of 18.5 m, there is protection for dry running.
The diameter of the nozzle in inches 3.0, weight 22 kg, maximum immersion depth up to 10 m, Aquario Sand-100 has a cable of 5 m, a minimum drainage level of 125 mm, the highest liquid temperature up to 40? C. Cable length 10 m, warranty period 12 months.
We clean sewerage
Note. There are several types of sewage cleaning pumps, where the presence or absence of a shredder, the installation method, the type of construction and the temperature of the pumped liquid are taken into account. We will focus on 4 main groups.
- Units that do not have a grinder, which are used for pumping cold water no higher than 40? C, that is, the temperature, which can be in the natural environment without any heaters. In the household, this type of apparatus is used to eliminate water during floods from flooded basements, cellars, and cesspools where solid waste does not enter.
- Units that do not have a shredder that are used to pump dirty hot water up to 90 ° C without solids. Such pumps are usually used in baths, saunas, laundries and dry cleaners. In the household, such modifications are practically unclaimed.
- Pumps that have a chopper, designed for pumping out cold domestic sewage with their own hands, the temperature of which does not exceed 40? C. Such modifications are most in demand, as they are able to process feces together with paper.
- Models with a grinder for pumping out of hot drains with a temperature up to 90? C. In everyday life do not apply.
Conclusion
To clean the objects, the drainage pump for sewage is used taking into account the contamination of the source and the presence of solid waste in it. In some cases, too thick a liquid diluted with water to reduce the percentage of impurities.
