The circulation pump is a piece of equipment that is particularly useful in heating, cooling and water supply systems. Here are some areas where it comes in handy:
Heating systems: A circulation pump is responsible for circulating hot water or heating medium between radiators, radiators or underfloor heating systems. This ensures that we reach the same temperature throughout the house or building and prevents the formation of cold spots.
Cooling systems: The use of a circulation pump in cooling systems helps to circulate the coolant more efficiently. This is used, for example, in cars or industrial cooling systems.
Hot water supply: A circulation pump allows hot water to be delivered to faucets and showers faster, saving time and water.
Pumps in water movement: Circulating pumps are often used in the water movement of pools, garden ponds, and other water systems.
Various industrial applications: Circulating pumps are also used in industrial environments, for example in material handling, cooling, process control or pumping systems.

For help, the plumbing thread dimensions are in inches and millimeters.

In the case of a solar collector system, it is recommended to connect it to a colder branch going to the collector. It is best if it is installed in the vertical branch going up.
The pump may only be installed with a horizontal motor shaft.
A spare part for heating systems.
Only an electronically controlled, energy-saving circulation pump may be installed in a new heating system. .

The purpose of circulating pumps is usually to move liquid efficiently and comfortably, to ensure heat transfer or to create conditions necessary for other processes. Using them can improve energy efficiency, the efficiency of the entire system, and save time in tasks related to moving liquids.
