How to use a circulating pump to last almost forever

Now almost every private house and apartment with individual heating has circulation pump. This is an integral part of the modern circuit of the heating system, although earlier they could do without this electrical appliance. The system was thought out so that its filler moves by gravity due to natural expansion when heated. But now the focus is not on practicality, but on aesthetics. And it is for this reason that now there is no way without a pump, but the pipes go to radiatorsas you please - even under the floor. You can rejoice at this fact or complain, but you have to put up with the fact that your heating now also depends from stable power supply, and from the serviceability of the motor itself. Today we will talk about how to properly handle the circulation pump so that it lasts as long as possible.

Basic rules for working with a circulation pump

There are basic rules, following which, you will not have problems with the circulation pump. First of all, it is not turned on if there is no coolant in the system. Heat carrier is a natural lubricant for the pump and at the same time a coolant. If you run the engine "dry", its parts quickly wear out.

The second important point is the interaction between the coolant and the pump chassis. Hard water forms a solid limescale on the parts, it is imperative to monitor the quality of the water and periodically clean the pump from deposits.

Never leave the heating pump unattended for the summer. One of the most common causes of breakdown is seasonal downtime. During this time, the oil seals dry out, and as a result, at the time of start-up, you will get a leak.

Excessive heating of the coolant may be the cause of malfunctions with the circulation pump. The maximum is 75 degrees. Heating above this temperature leads to the formation of salt deposits, which again deposits on the undercarriage.

What should alert you:

• Extraneous knocks. The reason may be the ingress of a foreign body into the coolant or overgrowth of the shaft with a deposit. Periodic cleaning and installation of a mesh filterthat will trap debris.
• The motor does not start. The reason may be a lack of contact in the power supply, a violation of the integrity of the wires or problems with the outlet.
• Humming of the engine. The reason lies in the airing of the system, that is, the formation of an air lock. Good imported pumps have a vent valve. If it is not there, you need to get rid of the plug by bleeding.
• Excessive vibration. The reason for this "signal" is the wear of the bearing, it needs to be replaced.
• Slow movement of the coolant. The filter needs to be checked and cleaned.
• Spontaneous shutdown of the motor. This is a serious cause for concern. It will not be possible to cope with the repair on your own - here you will most likely have to rewind the engine.

Bottom line: how to monitor the circulation pump

So, in order for the pump to work as long as possible, you need to listen to its work and, at the slightest sign of a malfunction, immediately identify its cause.
