Description

Pilot pump
A smaller pump in a pilot pump function is used as a supplemental pump in booster appliions. Its purpose is to take over in low consumption periods and thus contribute to lower the energy consumption of the booster as a whole.

A pilot pump takes over the operation from the main pumps in periods when the consumption is so small that the stop functions of the main pumps are activated. The pump is smaller flow-wise than the main pumps but is often able to supply higher pressure in order to ensure that the pressure in low consumption periods does not go below the system’s set point.
A pilot pump is often used to optimise energy consumption of a booster set. If an appliion has a consumption profile with continually flow in low consumption periods, it is often more economical to have a small pump running than starting and stopping the larger main pumps.
A pilot pump also has the benefit of reducing the needed size of the diaphragm tank, since the diaphragm tank is sized after the pilot pump thus reducing the footprint of the system as well as the amount of stored water.
