B.12
Pump by Rate
Pump by rate (2.8.1.8.) (Page 198)
starts pumps until the level is changing at the rate
specified in Filling indicator (2.3.9.) (Page 176) or Emptying indicator (2.3.10.) (Page 176).
Pumping costs can be less because only the highest ON setpoint needs to be programmed
and this results in a lower difference in Head to the next wet well which, in turn, results in
less energy being used to pump out the well.
B.13
Other pump controls
There are a number of other controls available to modify pump behavior.
Pump Run-ON
Run-ON Interval (2.8.2.7.1.) (Page 205), Run-ON Duration (2.8.2.7.3.) (Page 206)
Extends the RUN period for a pump based on a set time interval. This allows for the wet well
to be pumped lower than usual, and reduces sludge build-up on the well bottom.
Wall Cling Reduction
Level setpoint variation (2.8.2.6.2.) (Page 204)
Varies the ON and OFF setpoints to keep a fat ring from forming around the walls of the wet
well.
Pump Group
Pump group (2.8.2.2.) (Page 201)
Allows for two different Alternate Duty Assist or Alternate Duty Backup pump groups in the
same application.
Flush Device
Flush pump (2.10.3.2.) (Page 216), Flush cycles (2.10.3.3.) (Page 217), Flush interval
(2.10.3.4.) (Page 217), Flush duration (2.10.3.5.) (Page 217)
Operates a flush valve or special flush device based on the number of pump starts, usually
to aerate wet well wastewater.
