Chemical Pick-up Assembly, EPDM (1/2" Tube)
Model # 491403-A
Overview

This assembly features a higher volume check valve and thick 1/2" tubing, which allows venturi injectors to draw more chemical and create a stronger solution than a standard 1/4" chemical pickup assembly.  It also allows for a faster chemical draw rate using high viscosity (thick) chemicals.  Use this kit to replace a standard pickup assembly, or add a second pickup assembly to units with an unused chemical port on the injector body.  Available with EPDM or Viton check valve.

Key Features

  • High viscosity (thick) chemicals are drawn into a Venturi injector at a slower rate than water-thin chemicals, resulting in a weaker than expected dilution ratio
  • This assembly also allows the user to use thicker chemicals that do not draw properly through a standard 1/4" suction tube and check valve
  • Thick chemicals will still draw slower than water-thin chemicals, but this assembly will help diminish the effect
  • Replaces a standard chemical pickup assembly OR installs as a second pickup assembly on certain injector styles that include an unused (plugged) chemical port
  • The larger tubing and check valve allow units to achieve a stronger "no tip ratio" than the standard 1/4" suction tube and check valve
  • Metering Tips not included (#443798)

Includes

  • Stainless steel 1/4" street elbow
