Sewage pump which unit to choose, based on your needs

Often, sanitary facilities and appliances have such a layout that it is difficult to locate them in a dwelling, due to the need to be placed near sewers. In addition, horizontal pipes should be mounted with a slope in the direction of the riser, so that the drains go by gravity.

On this basis, it is necessary to install all sanitary devices next to each other.

Why do we need pumps for sewage

This problem can be solved by installing the pump. The use of such a unit will provide an opportunity to put a shower, bathroom, toilet, sink, dishwasher or washing machine where it is convenient for you. For example, a sewage system in the basement with a pump will allow sanitary devices to be located below the main pipes of the system.

Pumps for drainage network are divided into two groups.

They can be industrial and household.

1. The latter can pump sewage from one or several consumers. They are optimal for summer houses, country houses, small hotels, restaurants, cafes, shops, clubs.
2. Industrial pumps are installed in apartment buildings at substations connected to sewers.

Household units

Household pumps for sewage differ in purpose, installation location, design features. So, there are units that are mounted specifically for the water consumer, and there are sewage pumping installations for forced systems. The last units are located in septic wells or pumping stations.

Toilet Pumps with Grinding Device

1. This unit is mounted no more than 40 cm from the toilet, behind him. It has the form of a box, the dimensions of which are commensurate with the cistern.
2. The device is connected to the discharge pipe of the sanitary device..

Note! When draining water in the toilet, drains fill the pump. His steel grinding blades begin to grind toilet paper and feces. More dense garbage the unit is not able to grind.

1. When the garbage is ground, sewage flows through the pipes into the sewer riser.
2. Similar units can pump a column of liquid up to 10 meters high and up to 100 meters long..
3. As soon as the liquid is discharged into the riser, the flush lock of the toilet bowl is again filled with water..
4. Outlet pipes of the pump may have a cross section of 18/40 mm. This makes it possible to mount them behind the wall or ceiling cladding.
5. Sewage pumps with a grinder make it possible to put the toilet in any room, without regard to the location of the riser and the level of placement of the main pipes of the system.
6. The highest temperature of the drains that can pump such units (it depends on the model) varies from +35 to + 50 °.
7. Some devices are equipped with an additional entrance for draining drains from the shower, bidet, washbasin or urinal.

Note! If the temperature of the effluent is higher than stated in his passport, the unit may break. Some devices, therefore, are equipped with a protection that allows you to pump hot liquid for half an hour.

In addition to pumps, having the form of a box, with dimensions of 30? 45? 16 cm, embedded devices with a cutting mechanism are also available. They are intended for suspended types of toilet bowls. Their thickness is about 12 cm, thanks to this, the unit can be installed behind the GCR partition.

Kitchen mechanisms

1. Such devices are called "sanitary", because they only pump waste water themselves and do not have a shredder.. Discharge liquid when using such a unit should not include foreign objects.
2. Kitchen appliances are equipped with multiple inlets.. Due to this, they can be connected to the sink sink and additionally - shower, bath, etc.
3. They can be mounted in the sink closet or another convenient place..
4. When choosing, consider the maximum temperature of the fluid that kitchen pumps can pump.. So, models for a sink, a bidet and a shower are calculated on temperature of drains no more than + 50 °. Therefore, they cannot be connected to washing machines and dishwashers.
5. So that you do not threaten a quick repair of the sewage pump of this category, it should be periodically cleaned of fat deposits..

Pumps for operation at temperatures above + 75 °

1. This type of sewage pump stands alone. Such devices are able to divert sewage from all kitchen and plumbing appliances that use hot water without affecting their performance.
2. It is possible to connect a sink, sink, dishwasher and washing machine, shower, bath to this unit.
3. In normal mode, the device pumps the liquid, the temperature of which is no more than + 75 °. A short time (usually - about 30 minutes), such pumps are able to withstand temperatures of +90 degrees.
4. The price of such devices is 400/500 dollars.

Submersible devices

Experts call these units “fecal submersibles”.

Their design and installation method are radically different from the analogs that have been described before.

1. Submersible devices are mounted in a well or a tank in which drains from the entire building accumulate. This may be a cottage, a country house, a restaurant, a club, and another building that has an autonomous drainage system.
2. Fecal sewage pumps are equipped with a powerful motor and a cutting device. It can grind not only toilet paper and fecal masses, but also household gloves, towels, intimate hygiene products, etc.

Note! Devices can not cope with stones and metal objects. Therefore, you should ensure that they do not fall into the sewer. Otherwise, the unit may break.

1. When foreign objects are crushed, the waste fluid is pumped into the septic tank, in which it is cleaned.
2. Cases of devices and the grinding mechanism are made, as a rule, from steel-stainless steel or cast iron, less often - from impact-resistant plastic.
3. A submersible pump is often equipped with a signal float. When the well is filled, the fixture lets you know that it is time to turn on the drainage of the effluent. The second float turns off the pump.

Industrial analogues

Sewage pumps of the industrial group are used in multi-storey (multi-storey) houses, cottage settlements, remote settlements and enterprises, at facilities for pumping sewage into sewage main pipelines. The same units are mounted at the stations - pumping and for sewage treatment.

Submersible fecal pumps

1. The instruction reports that such devices are operated continuously, immersed in drains.
2. Based on the fact that the mechanisms are all the time in a hostile environment, their bodies and parts should be made taking into account the standards for resistance.
3. This kind of pumps is popular due to the fact that they are installed inside the SPS (sewage pumping station). Therefore, they do not need to allocate a special area and install a separate pipeline.

Note! It must be said that many models of submersible units are also suitable for “dry” (external) installation. In this case, it is necessary with your own hands to correctly bring the pipes and organize support on the inlet pipe.

Console units

1. Such mechanisms are openly mounted in the basements of multi-storey buildings, as well as in industrial-sized KNS.
2. Their main difference is that the pump itself and its engine are placed separately from each other and are mated by a clutch.
3. With proper use, cantilever sewage pump can serve for a very long time without accidents and breakdowns. If you need to repair it, it is not difficult to maintain the unit, because it is located in plain sight.

Dry installation self-priming mechanisms

1. Such mechanisms are mounted in a separate room on a specially equipped platform, inside the CND.
2. The units have excellent technical characteristics, they are convenient to maintain. However, the cost of mechanisms is quite high, so they are used relatively rarely.
3. When choosing such an industrial pump, you should buy it from the company that can provide you with professionals for its installation, accompanying diagnostics, maintenance and, in case of need, repair.

Conclusion

Choosing a pump for your home, read its characteristics and instructions for use. Purchase only the unit that is best suited for your sewage system. The video in this article contains much more useful information for you.
