Equipment for autonomous sewage systems must serve for a long time, operate without failure and not cause any problems with breakdowns. How to decide on the model and buy the most suitable fecal pump with grinder? After all, the list of responsibilities of this equipment includes not only pumping aggressive liquids, but also processing large organic particles.
For fans of country life, we will tell you in great detail everything about the design features and guidelines for choosing the right fecal pump. With our help, you can easily find and purchase the optimal model with the required performance and excellent technical characteristics.
The article presented to your attention describes in detail the types of fecal pumps and outlines their differences in design and operation. For potential buyers, a rating of models in demand on the market is given. The information is supported by photographs and video instructions.
Sewage pump grinders
Mechanical working elements - grinders - are an integral attribute of the fecal pump. The purpose of these elements is obvious: cutting, crumbling, dividing large and dense contents into small parts, which enters the pump along with the pumped liquid medium.
Different pump models are equipped with different shapes of grinders. Each manufacturer tries to achieve maximum effect. However, practice shows that changing the configuration of the chopper does not have a significant impact on the process. All grinders cope with the task quite successfully - they provide free passage of the pumped medium.
Typically, pumps contain grinders made like:
- impellers with blades-knives;
- cylindrical scissors-knives;
- cross-shaped cleaver;
- “meat grinder” type cutter;
- plate cutters.
Each type of cutter is practically no different from all the others in terms of efficiency. Another thing is the durability of the element. There is a direct dependence on the grade of steel.
This is what one of the design options for a fecal pump grinder looks like. The so-called “meat grinder” knife cuts large debris into small fractions up to 15 mm in size
Among the latest developments, the German design of the HOMA A-series submersible fecal pump, which uses an innovative grinder solution, attracts attention.
What to choose from the offered range
Equipment with the most efficient shredder design
The market offers a wide range of Grundfos pumps, equipment manufactured in Poland, as well as products manufactured in Russia and Ukraine.
Based on application experience and reviews from friends, I will say that the best option in terms of performance and versatility of use is Grundfos.
Shredder on a Grundfos plant
Such sewerage pumps, along with liquid waste, easily grind rags, paper and anything else that might accidentally end up in the sewer. Moreover, equipment of this brand (depending on the model) has several degrees of protection, and therefore there is no need to fear its premature breakdown.
Grundfos pumps are moved along specially fixed guides
But there is one drawback that cancels out all the advantages - the high price. An average performance model of a fecal pump for furnishing a cottage will cost about 2 thousand dollars.
An inexpensive alternative is equipment of domestic and Ukrainian production. But, as a rule, price is the only significant advantage. Why?
The most important structural element in the design of a sewage pump is the grinder. This is a knife made in the form of a small propeller. This knife rotates in front of the inlet holes into which sewage passes.
In the domestic pump that I happened to use, the chopper was located about 5 mm from the body. In addition, the edge of the chopper was not sharpened. For comparison, in imported equipment, the edge of the chopper is sharp, and the distance between it and the body does not exceed 1 mm.
What might such differences in design lead to?
The efficiency of such a chopper is ensured by a sharpened edge and precise adjustment of the gaps
The shredder with a small gap and a sharp edge cuts well any inclusions, from feces to indoor slippers. Models with a large gap between the chopper and the body, and a blunt edge, only cut feces, and even then they do not cut, but break. This shredder does not cut rags and similar debris, but rather tears them up. But, sooner or later, the rag gets wrapped around the chopper, the shaft jams and the motor winding burns.
By the way, for obvious reasons, no one is eager to repair fecal pumps that are broken during operation.
Control unit - one completely sealed button
What to choose? Pumps manufactured in Poland (OMNIGENA, IBO, etc.) are still on sale. The shredder functionality is fine here. The price of such equipment is higher than the cost of domestic developments, but also lower than Grundfos costs. In my opinion, this is not the worst choice.
Equipment operating parameters
The power source for pumping equipment is usually a stationary electrical network. At the household level, the voltage is traditionally 220 V, but in industry and agriculture equipment with a voltage of 380 V can be used.
The following parameters are also important for the future owner:
- power (for domestic use 0.5 - 1.5 kW);
- productivity (150 – 600 l/min);
- height of the liquid column – pressure (10-20 m);
- operating fluid temperature (+1… +40 ºС);
- working environment temperature (+1…+40 ºС);
- degree of density of the pumped medium (up to 1200 kg/m3);
- acidity level of the working environment (Ph – not higher than 10).
Work with pumping equipment must take into account the specified parameters; moreover, for each individual model, the noted indicators can be expressed in specific values that cannot be exceeded.
Price of sewerage equipment
The cost of modern fecal equipment with a grinder is considered quite high. Despite this, it is recommended to buy only high-quality products, because in this case the sewage system will last quite a long time. In this case, accidents or minor breakdowns will not occur.
The price of the simplest budget models is 11–17 thousand rubles . Silent household units will cost 20–37 thousand rubles. The most expensive equipment is considered to be from famous manufacturers, including Grundfos. Such high-quality products are offered at a price of 40–70 thousand rubles. Naturally, you can also find more expensive premium units on sale.

Maximum power – 1.5 kW. The material is the steel blade of the chopper knife and the cast iron body of the pump itself.
Calpeda . Fifth place in the ranking was taken by the Italian product Calpeda GMG, which surpassed even the Germans in price. However, the high cost of this equipment is compensated by its high reliability and durability. This model has one important detail - the presence of self-sharpening chopper knives.
A fecal pump with a self-sharpening grinder from Italian manufacturers is designed for operation in extreme conditions. The design allows immersion to a depth of up to 20 meters. During operation, a pressure of up to 40 meters is created. Productivity indicator – 16 cubic meters/hour.
A powerful device from an Italian manufacturer is the Calpeda GMG fecal pump with a grinder, which is equipped with a self-sharpening mechanism. Equipment whose service life depends only on the natural wear of parts
This is what the rating of the best pumping equipment from the group of fecal systems looks like. Of course, this list should be taken purely conditionally. The range of pumping equipment is very large, and only five models are not able to show the situation completely. But when choosing a pump for everyday use, it is quite logical to focus on the designated list.
