FUNCTIONING

4.1 PRODUCT DESCRIPTION

4.1.1 MOTOR PUMP

•
The system is composed of a motor
pump and an electronic control system
(inverter) that enables the pressure to
be maintained constant in the system,
reducing or increasing the rotation
speed of the pump motor
26
•
When the system pressure goes
below the threshold set, the module
starts the pump to reset the set
point pressure; the rotation speed of
the pump varies based on the water
request, therefore, greater request
requires greater speed, until the
maximum set pressure is reached
•
When the request for water decreases,
speed will also reduce until the pump
reaches the minimum speed set and
after which, if there are no further
decreases in pressure
(i.e. new water requests), the pump will
go in stand by until a new cycle begins
