SERIES B Injectors incorporate an externally adjustable, internal by-pass valve in addition to the chemical injection metering screw. This feature eliminates the need for water flow nozzle bushings, extends the flow range of the injector and easily adapts to variations in liquid flow due to pump or spray nozzle tolerances resulting from wear or partial line clogging.

SERIES BP Injectors use a special corrosion-resistant metering screw which can handle fluids containing Sodium Hypochlorite or Hydrofluoric acids. Injectors are complete with 8 feet of clear Vinyl tubing with strainer and a drum protector disc.

MODEL BS Injectors feature a stainless chemical block and are for pressures from 700 - 3000 psi.
