60/20 High Flow Level Master™

Model # 989108

The 60/20 High Flow Level Masterâ„¢ is a water driven chemical proportioner that will automatically refill the 60 gallon tank with ready-to-use chemical solution. When the solution in the tank drops below a pre-set level, the float valve triggers air-activated solenoids to start the water flow. Using city water pressure (35 - 125 PSI), this venturi injection system draws and blends chemical concentrate into the 21.2 GPM @ 40 PSI water stream to create an accurately diluted solution. The system cycles continuously and a secondary fail-safe float prevents overfilling.


Key Features
  • Automatically maintains a pre-set level of ready-to-use chemical solution in a 60 gallon tank
  • Refills at 21.2 GPM @ 40 PSI to provide chemical for a central chemical feed system
  • Dual magnetic float valve design includes a primary valve to regulate normal operation and a secondary fail-safe valve to shut off the system if the primary float valve malfunctions
  • Unsinkable solid polypropylene floats suspended by rigid "push rods" ensure smooth operation and prevent the float valves from sticking in the open position
  • Dilution ratio controlled with precision metering tips
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
  • Industrial-strength design holds up in tough environments
  • Available with a lower flow rate (#989106)
  • See all of our Level Masterâ„¢ configurations and other Lafferty chemical management systems in Catalog 9
