In heating and air conditioning systems, water must be distributed from the supply system to the point of consumption. This is done by means of main pumps.
Larger systems can be divided into several pipe circuits with each their local pump. The main pump is the pump that distributes the total amount of water from the supply source.
Due to variations in heat demand and flow in large systems, it is recommended to use speed controlled pumps in parallel as main pumps. By using speed controlled pumps it is also possible to obtain maximum energy savings.
A maximum of three pumps plus one standby pump is recommended.
