7 GPM Gemini High Flow Level Master™

Model # 989072

The 7 GPM Gemini High Flow Level Master™ is a water driven chemical proportioner that will dilute and blend 2 chemicals and automatically refill a customer-supplied tank with ready-to-use chemical solution at 7 GPM @ 40 PSI. When the solution in the tank drops below a pre-set level, the float valve triggers an air-activated solenoid to start the water flow. The unique Gemini™ "double venturi" injection system combines two completely separated venturis in one injector body and uses city water pressure (35 - 125 PSI) to draw and blend 2 chemical concentrates into the water stream independently so that the chemicals never mix until they are diluted. 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 customer supplied tank
  • The unique Gemini™ proportioner draws 2 chemical concentrates and blends them downstream after dilution
  • Dilution ratios are controlled independently for each chemical using precision metering tips
  • Refills at 7 GPM @ 40 PSI to provide chemical for a user-supplied 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
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
  • Industrial-strength design holds up in tough environments
  • See all of our Level Master™ configurations and other Lafferty chemical management systems in Catalog 9
