FEATURES AND OPERATING CYCLES
1. Prior to shipping, the tank
is pressurized to a standard
precharge as defined in
the “OPERATION” part of
this manual.
2. As water enters the
tank, the air above the
diaphragm is compressed
and its volume is reduced
by the volume of water
that enters.
3. The pressure in the tank
rises. Water continues to
enter until the pump cut-out
pressure is reached. The
pump shuts off and the tank
is now filled.
4. The pressure in the air
chamber forces water into
the system when a demand
occurs without causing the
pump to operate immediately.
Pressure in the chamber
finally drops to the pump
cut-in pressure, the pump
switch activates the pump and
repeats the filling cycle.
The Water Systems Tank Concept
The water system tank does more than simply store water. It
helps to protect the system components. A properly sized tank
will provide adequate flow even when the pump is not running. It
saves energy by reducing the number of pump starts. In addition,
the water system tank provides increased system component life
due to fewer pump cycles.
The water system tank consists of a steel tank (A) containing a
sealed-in-place heavy duty diaphragm (B) which separates air
from the water. The portion of the tank where water is stored (C)
is lined to isolate water from the metal tank. This protects the tank
from internal corrosion.
