| **B |
Max. sunction capacity using 8 mm. O.D. pickup hose and suction regulating unit or restrictor |
Chart key:
- The restrictors regulate the chemical suction capacity. Restrictors are available with a suction regulating capacity from 2 - 100 l/h. The restrictors are designed to be assembled easily onto the injectors regulating mechanism.
- Minimum flow rate of water is required to pass through the injector to prompt the Venturi complex to start chemical suction. The required flow rate will vary at different inlet pressures (see chart).
- Head loss is required for the injector to operate. The head loss will vary according to inlet pressure and suction capacity
