Muds for heating systems: description, operating principle
When water is selected as the coolant, all metal elements of the heating system gradually rust. First of all, the pipelines suffer. Corrosion also destroys structures made of metal, and it is also dangerous because fragments of rust exfoliate and clog the heating system. In addition, the system is clogged with particles of sludge, mud, sand, etc. Therefore, special cleaning is required, for this purpose mud pumps are installed for heating systems.
Appointment
These devices are designed to clean the coolant from medium and large suspended particles in hot water, heating and heat supply systems for ventilation equipment.
Design Features
Muds for heating systems externally represent a pipeline extension unit with water filtration by a special grid and changing its direction. Under the grid, clipping, sedimentation and subsequent accumulation of medium and large suspended particles are carried out.
Muds should be installed in such a way that free access is provided for cleaning and inspection. In most cases, they are installed on the TP control nodes and the entrances to the building.
Varieties
Depending on the method of installation, type of attachment and design, this equipment can be presented in the following versions:
- With flange connection.
- With threaded connection.
- Subscriber.
- Horizontal.
- Vertical.
The design and the device of the filter assume the presence of a detachable branch pipe or bottom to remove the filtered fragments, as well as a crane for lowering air and coolant.

Conditions for normal operation
The condition for the normal functioning of the filter for cleaning the heating water is a gradual increase in the hydraulic resistance in it for the indicators of the devices that are before and after this equipment.
Passport
Another important point, which should be stopped - is the passport, which should be in the delivery kit of the mud maker. The following important information about the device is reflected in this document:
- Marking and delivery set.
- Information about the manufacturer.
- Compliance with GOST or TU.
- User's manual.
- Dimensions and technical characteristics.
- Conditional designation, purpose and name.
Additional benefits
Mud helps fuel economy. Using this water filter (photo below), you thereby protect the convective elements of the boilers - this, in turn, maintains their high efficiency and does not increase the volume of fuel. Accordingly, there is no over-expenditure of fuel, which leads to impressive financial costs.
In addition, the mud filter allows you to significantly change or pump up water in the heating system, which also contributes to savings, since you do not need to expend reagents and excess electrical energy. The volume of the coolant that is discharged into the sewage system also decreases.
The cost of these devices may vary, depending on their type and size. The most common is the mesh filter for water (the photo is shown below). On such equipment, the filtration mesh is built into its housing.
Principle of operation
The principle of muders of any type is carried out according to an extremely simple scheme:
The coolant enters the nipple and then flows into the body. Dirt particles settle on the bottom.
Then the water from the internal cavity of the sump enters the filter installed in the outlet branch pipe.
After that, the purified heat carrier enters the pipelines of the heating system.
Cleansing of particles of dirt occurs by removing the glass from the outlet nozzle. The lower part of the sump body must be periodically cleaned of accumulated dirt. The mud filter is connected to the pipelines both by threading and by means of flanges.
An excellent invention is considered to be mudspots of the magnetic type. Rust is attracted to the magnet, which in no way affects the intensity of the water flow in the heating system. The particles caught by the magnet accumulate in specially designated places for this purpose.
Due to the fact that mud pumps for heating systems do not change the pressure, they can be used on the suction line of high-power pumping equipment. In this case, the magnet is externally a thin cylinder with a diameter of about 40 mm.
Some consumers doubt that installing a sump on a heating system pipeline is so important. Those who believe that the system will function perfectly without this device, it is worth saying that, of course, you can do without it. But at the same time, the operational life of the system will be significantly reduced due to pollution and other factors associated with this. And also the efficiency of the heating system will be reduced.
The advantages of this product are undeniable, especially when the operation of the heating system requires frequent cleaning of boilers and pipelines. Also, mud collectors come to the rescue in winter, when the heating devices are not yet warm enough.
So, the advantages of a sump for heating systems are obvious. And its cost is relatively low. So do not worry too much about whether to install a filter for the heating system. Of course, to purchase this product is much more profitable than dealing with the elimination of any breakage or replacing the piping system.
It is also worth considering the moment that, in addition to financial costs, interruptions in the operation of the heating system can bring a lot of emotions.
With the mudman, the system will function reliably, and most importantly - the probability of emergencies will decrease.
