Tips for Aquavar Variable Speed Drives For
constant pressure applications a bladder tank is used to
maintain line pressure during a zero demand condition. The
tank is also used to absorb water hammer caused from pump
starts/stops and the fast opening/closing of valves. Single
Pump - Constant Pressure
For single submersible pump applications, a tank with
approximately 20% of total system volume in GPM would be
recommended. Single
Pump - Submersible Pump Constant Pressure
For single submersible pump applications, a tank with
approximately 20% of total system volume in GPM would be
recommended. Multi
Pump - Constant Pressure
Similar to the single pump constant pressure system, the
multi-pump system should have a diaphragm or bladder type tank
for system cushion. The tank should be rated for the maximum
system pressure, and be sized for 10-25% of the single pump
capacity. This is total tank volume, not drawdown. If you have a
triplex system of 167 GPM per pump capacity, then your tank size
should be a minimum of 17 Gallon capacity. Go to the next
higher tank volume if you have a suction lift or flooded
suction. The tank provides small drawdown capacities on
drive start up and provides a “cushion” for the entire
system at normal operation and will provide compressibility at
shut-down. The tank pressure will greatly improve system
operation. A larger tank is acceptable and sometimes required,
just do not exceed 50% volume of the flow for one pump, this may
cause system problems.
