This is not such a simple question...Its not extraordinary to set condensing capacity sequencers such that the pumps on all condensers are the first thing engaged; whether its the smartest way to operate depends on a lot of plant specific factors.
If your climate and your duty cycle is such that 1) you have a remote sump some distance from the condensers and 2) your capacity requirement increases to near-100% very quickly, you may run into discharge pressure problems and compressor jackedet or thermosyphon oil cooling problems if you try to operate without the water "already at" the condensers.
Paralleled evap condensers are always going to have some minimum refrigerant flow. So, if you shut water flow off frequently on a particular condenser, you will tend to "soft scale" the coil. If you happen to be in a season where there is a lot of airborne debris (maple keys or poplar bolls or even sawdust) keeping the water flowing may prevent plugging the nozzle deck or the underside of the eliminators.
You can also encounter strange water treatment scenarios as well as de-passivation of the galvanizing on your coils by letting a single condenser's coil alternately go from wet to dry....That dependent to a large degree on your makeup water content as well as bleed rates and water treatment intensities.
The accepted generality is: if you can live without the water flow for an extended period, like days, take it out of the sequence; if its going to start today, you might as well start it this morning.
