FUNCTION
When a tap is opened, water is taken from the diaphragm tank. Then
the pressure drops to the first cut-in pressure, and the first pump is
cut in. As the consumption rises, more pumps will be cut in until the
performance of the pumps in operation corresponds to the
requirement.

When the water consumption falls, the discharge pressure rises to

the cut-out pressure and the LE 1000 Controller cuts out one pump.

As the consumption falls, more pumps will be cut out.

APPLICATIONS
Lubi Aquapack 1000 booster sets are designed for the transfer and Please see fig. 1 which explains how the pumps will operate based
