MC 9200 Dosing Pumps

The PULSAtrol MC9200 Series provides microprocessor based control for recalculating cooling water systems. The MC9200 Series comes standard with a mounted flow assembly, a pre-wired selectable timer (except MC9220), alarm output relay, dry contact alarm output and water meter totalizer. All continuously monitored sensor input functions (conductivity, pH) will provide user definable set points for maintaining a specific value within the system. Each set point will have a user definable differential as the control band, programmable high and low alarm points and user defined limit timer for pH.


  • One user selectable chemical feed timer and up to two 28-day event timers
  • Lockable viewing window
  • Two point calibration
  • Dry contact water meter input capability
  • Alarm powered & dry contact relays
  • Optional 4-20mA output capability
  • Alarm LED
