VA 603-320, P2 453413 Louisville VAMC Replacement Phase B
22 11 23 - 10
system discharge pressure versus suction line pressure and provide
an analog signal 4-20mA to the pump control software, and allow the
variable speed pump controller, to provide a variable Volts/Hz
output to the motor. Once the pressure drops below the set system
pressure, the pump shall start and provide system pressure (as
determined by the station operator or program), if this pressure
cannot be maintained by one pump, the next pump in sequence shall

2. The pumping system includes multiple pumps as indicated above. In
three-pump systems, the lead pump, lag pump, and stand-by pump
normally satisfy demand in three stages. The first (lead) pump
operates initially, until the water demand exceeds the lead pump’s
capacity. The second (lag) pump starts and the lead pump stops,
allowing the lag pump to operate until the water demand exceeds the
lag pump’s capacity. At this point, the lead pump restarts, and
operates concurrently with the lag pump to add capacity when needed.
The third pump is a stand-by pump, ready for operation if the lead
or lag pump is taken out of service and the system demand requires
two pumps. The system is to be configured so that at least two pumps
can be in service if any one pump is taken out of service. Pump
assignments shall alternate to automatically equalize the run time
in similarly sized pumps, which excludes uniquely-sized lead pumps.
3. The pump logic controller shall provide the following standard user-
selectable features:
