Fecal pump: types, types and main characteristics of devices - Setafi

For homeowners, a common problem: they dug a cesspool, it worked fine for 2-3 years, and now there is nowhere to put sewer waste. Ordering vacuum trucks is an expensive pleasure, but there is no other option in mind. But we have, and you can still earn extra money on it by helping your neighbors.

In our article we will talk about an indispensable device for a private house - a fecal pump; we will present our rating of characteristics for choosing the right equipment. Go!

What is a fecal pump for - a brief explanation

Any type of fecal pumps is indispensable both in industry and for private households, small farms. A small pump can pump liquids, such as sewage and other types that contain solids.

For domestic use, devices are produced within the range of 5-25 cubic meters per hour. This is the optimal indicator of power in order to clean the sewer for yourself and to help your neighbors if possible. In industrial devices, the power can be ten times higher.

Consider for what purposes in everyday life you can buy a pump:

• For draining wastewater.
• Water from cellars and cellars. The situation is especially relevant in the spring: the snow melts, and the basements collect all the water.
• Collecting water from a well or other artificial source before cleaning it.

Some types of fecal pumps can work in other areas as well. For example, they are installed for distilling water in large tanks, irrigation systems on farms, and so on. Although the pump is “fecal”, there are much more applications for it than the name suggests.

There are even devices with solids grinders so that the mechanism does not clog and the pump does not overheat.

How to choose a sewer pump

Since the pump must operate under conditions that are not typical for a standard pump, additional performance characteristics are required for it. Therefore, beginners often ask the question: “which sewage pump is suitable for my situation?” and other moments.

Firstly, the body material is resistant to corrosion and aggressive environments. Quality materials: stainless steel, bronze, steel or cast iron. If the device in the store is made of something else, then it is better to bypass it and not spend money.

Secondly, the operating temperature. Not all pumps are capable of operating above 40 degrees Celsius. If the drains are too hot, the model may overheat and no longer turn on. Therefore, for hot springs, specifically select a device with suitable heat resistance parameters.

Thirdly, the features of the liquid itself. It is heterogeneous - there are elements of different fractions, paper, organics and other materials. To process such material, a grinder is installed in the pump.

If the device does not have a grinder, then it is called drainage. It is similar to faecal, but does not work in a medium with large fractions. He will still try to transport organic matter up to 3 cm, but alas, for more. The drain pump is great for pumping bathtubs, pools and other clean water tanks.

Which pump is better for pumping sewage - for a guarantee, take it with a grinder. If you are going to work only with cesspools, this is an indispensable tool. Drainage is cheaper, but will not help.

What pump is needed for pumping sewage - basic models

To figure out how to choose a sewage pump, the description of each of the devices below will help. It is enough to look at the situation, compare with the description and buy a suitable pump.

Submersible sewage pump

A key feature is that a float is installed in the design of the apparatus, by which the level of wastewater is determined.

The body is made of materials resistant to aggressive environments - cast iron or stainless steel. The model is completely sealed and protected from liquid ingress.

The main task of the fecal pump is to pump wastewater. It is also used for drawing water from a well and watering beds. Therefore, this design is universal for a private house.

The device is submerged below the water level. Adjustment is carried out by float. If the pump is not under the drains, it will not work. If necessary, the design is regulated by guides.

semi-submersible pump

This model is distinguished by a smaller diameter of the channel for the liquid than that of the submersible. Therefore, some restrictions are imposed on their use. The system can only be used where the diameter of the solid fractions is not more than 15 mm.

Of course, some models have a chopper. But a larger diameter will not fit into the fecal pump channel, no matter how hard you try.

The pump handles sewage, oils and viscous liquids. They have proven themselves as a component of a private sewer system.

The device works when its lower part is in the water, and the top is open. The upper part is held by a float.

Surface fecal pump

A feature of the external design is ease of use and mobility. They are not installed inside the water, but function outside the pit or tank.

Models of surface pumps do not differ in special power and throughput. The maximum diameter of solid particles is even smaller - up to 5 mm.

The case of the device is not sealed, so it is better not to leave it in rainy weather in an open area. This and other shortcomings are fully compensated by compactness and cheapness. And most importantly - the pump can be moved as you like and anywhere.
