How to choose the right circulator pump..!

Quote

Circulator pumps are used for the circulation of gases and liquids in a closed circuit. The fluid runs through the system in a loop, continually returning to the pump which maintains its pressure. These pumps have applications in domestic, commercial and industrial domains.

Some of the most common uses for a circulator pump can be found in the circulation of water as part of heating or cooling systems. In a water heating system, the pump is used to push hot water through pipes around the building, often using radiators to heat each room.

The size and power of a circulator pump can vary depending on the application, taking into account the type of circulation fluid, its flow rate and operating conditions.

** Pumps with aluminium or cast iron casing, containing bronze or stainless steel internal components, are usually suitable for systems that use water. However, in systems which use highly corrosive fluids or operate at high temperatures or pressures better performance can be ensured with pumps made from titanium, metal alloys, and chemically-resistant plastics **

Working out which circulator pump you need yourself is not an easy task! Please do not hesitate to contact a professional, we are happy to help you here at ATAC Solutions. However, we will need a few things from you so please be prepared with the following..

1. Measure the size of connection
2. Face to face distance – length of the pump from inlet to outlet
3. Static head – distance from the lowest to the highest part of the system
4. Flow rate – be prepared with number of radiators, type of boiler, type of house (how many floors). (If the flow rate is correct you will get maximum output from the system)
