Circulator pump and piping
The selection of the pump is fundamental for the system to obtain its maximum efficiency and is
determined at the design stage. For installation details please refer to the manufacturer's manual
supplied with the pump. To size the circulator pump, the pressure drop of the system throughout the
circuit at the known design flow rate must be calculated. Remember that as the system flow increases,
so does the pressure drop exponentially. It is common practice to oversize the pump by at least 15%,
i.e. the pump pressure, at a given flow rate, is at least 15% higher than the system pressure drop.
The selection of the piping is critical to the proper functioning of the system and will be determined at
the design stage. The installation and pipe diameters will meet all standards and specifications
applicable in the location where it is installed. As a general rule, the speed of the fluid inside the pipe
should not exceed 2m/sec, although it is recommended that it be sized with 1m/sec, because, with the
use of the installation, a layer tends to be deposited inside the pipe that reduces the useful area of the
pipe.
Note: The recommended flow is 60 liters per hour per collector.
