How to choose a fecal pump with a grinder

In the private sector, there are frequent situations where the homeowner does not have the ability to connect his sewer network to the general waste disposal system, which is why he has to build an autonomous system. An integral part of such autonomous systems is a sewage fecal pump. In this article we will tell you about how to choose a fecal pump with a grinder, and also examine in more detail its two main varieties.

Areas of use

The equipment of the type we are considering can be used both in private farms and in collective use institutions (cafes, snack bars and other catering facilities) that are not able to be connected to the city sewage system. Since in this case the risk of various debris entering the sewage system increases dramatically - the autonomous system must necessarily be equipped with a special grinder for solid particles of sufficiently large size.

In addition, the sewage fecal pump can also be used to draw water from water bodies, i.e. These devices are capable of solving a whole range of tasks related to the daily maintenance of small private farms. Before buying equipment, we recommend that you first familiarize yourself with known types of pumping systems of this class, as well as with their main characteristics.

Units of the outer (surface) type

Pumps of this type are usually installed directly behind the toilet (or under the sink) in the bathroom. When choosing a place for such equipment, it is necessary to ensure that it does not take up too much space and does not block the passage.

When getting acquainted with the characteristics of the model offered to you, be sure to pay attention to the design of its cutting and crushing mechanism. With particular attention will also need to explore the list of those materials that he is able to "process". It is desirable that it does not include other types of "junk" material, except:

• toilet paper of any type;
• plastic waste;
• soft food waste;
• small pebbles and pieces of glass.

In addition, you should pay attention to the stability of the model you choose to the effects of aggressive media (with chemical, oil and sandy mud components).

Submersible equipment

The submersible fecal pump is intended for work in the conditions of immersion in this or that liquid medium and can be used for pumping both the pure, and polluted water. Basically, such pumps are used for technical needs related to cleaning small ponds, sewage tanks or for emergency pumping of mud drains (from basements, for example).

When choosing a submersible pump, first of all it is necessary to make sure that it has a float-type switch that ensures the operation of the unit in automatic mode (with simultaneous protection from the so-called dry run).

It is desirable that in the model you are purchasing there are on and off modes that are tied to a specific position of the float (the level of the pumped liquid). In this case, your pump will turn on only in a liquid medium filled to a certain level, and after a full pumping of waste, it will automatically shut off.

Installing a fecal pump with a flexible hose connected is usually not difficult and consists of lowering it in a pit of liquid. If the installation of the pump will be made to plastic pipes, then this work is more difficult.

It is important to remember that any pumped liquid is aggressive. And in any case, it will always contain one of such caustic substances as:

• salt components;
• acid;
• alkali;
• organic waste, etc.

Only this explains the requirement for maximum protection of the inlet and outlet nozzles of the unit (as well as all its working wiring) from any contact with the pumped liquid.
