Recirculation pump; It is a special type of pump used to circulate gases or liquids in a closed circuit. Because they only circulate the fluid in a closed circuit, they only have to overcome the friction of the piping system (as opposed to lifting a fluid from a point with lower potential energy to a point with higher potential energy).

What is Circulation Pump?

The circulation pump is the name given to the devices that ensure the progress of the water circulating in the system. Circulation pumps are required for the circulation of liquid in closed circuit heating and cooling systems. They circulate the liquid in devices such as combi boilers, boilers and the like. In heating systems, the water heated in the boiler overcomes the resistances in the installation and ensures that it is transmitted to the heat emitters. Circulation pump selection is important for heating systems. We can say that the circulation pump is the heart of the heating systems because it functions just like the heart in the human body. It has an important task in terms of providing liquid flow even to the farthest points. Circulation pumps are types of pumps used in heating systems and hot water circulation. With the invention and use of circulation pumps, modern heating systems have also reached higher levels. Thanks to the circulation pump, the pipe diameters were reduced and heating was provided with more efficiency at lower temperatures. As we said at the beginning of our article, the heart of the hot water heating lines is the circulation pump. Thanks to the circulation pump, a small amount of hot fluid is kept in the pipes so that the fluid does not cool. Hot fluid always circulates in the pipes and the heating time of the fluid is shortened. Thus, efficiency is achieved.

What Does a Circulation Pump Do?

The main task of the circulation pump is to ensure the progress of the water circulating in the system. It plays a very important role so that the water heated in the boiler can reach the heat emitting devices, overcome the resistances and provide movement. The circulation pump provides many benefits with it. Let’s summarize them under a few items;

  • Waste of water is harmful in every way. It has harmful consequences not only economically but also in many respects. The circulation pump is a powerful equipment in terms of preventing water waste. Because, thanks to the circulation pump, there is hot water at all times and thus no waste of liquid is experienced.
  • We know that most places do not need the hot liquid they need 24/7. When not needed, no liquid accumulates in the pipes. Thus, it allows you to save energy and money.

It is enough to follow a few steps for the circulation pump assembly. If the installation where you will install your pump is new, it is strongly recommended that you do an internal cleaning first. Take care to use heat resistant gaskets during assembly. Ensure that the arrow direction of the pump points towards the boiler and also secure the electrical components of the pump with an electrical panel suitable for the highest current specified on the pump. Set the stage where you will use the pump. Grounding in the electrical installation is an important detail. If the pump is to be used in cooling installations, take precautions against freezing and pay attention to the isolation of the system. If the pump will be at lower levels, such as in the basement, then it would be beneficial to make a drainage pit to prevent flooding. If necessary, a drainage pump can also be used.

How to Select a Circulation Pump?

There may be different fluids such as boiling water, hot oil, steam, and these fluids may be performing the heat transfer in the system. The main thing to consider in the selection of the circulation pump is the purpose of use and the fluid. After determining for what purpose and where the circulation pump will be used, which fluid will be used is one of the factors affecting the selection. One of the things to consider when choosing a circulation pump is flow rate and head. Flow rate is the scale that determines the amount of water that must circulate in the installation in order to heat the building. It must comply with the relevant standards.

How is Circulation Pump Air Taken?

Before the water is supplied to the installation, radiators, connections, valve connections, radiator plugs should be checked and tightened if loose. One of the biggest problems in the heating installation is that the radiators or some parts of the installation do not heat up or heat less than other places. Likewise, noise coming from the radiator system is one of the problems encountered. The reason for this is the air present in the water. Especially when heating systems are filled with water for the first time, air cannot find a place to escape in the pipes in the radiator and gets stuck somewhere. Due to this compression, water passage is not allowed and thus the heating problem arises. To take the air, the first thing to do is to rotate the plastic part on the air vent and bring it to the down position. Water may squirt out during the air outlet, so make sure you have a container. from the circulation pump
