3-5 GPM Downstream Chemical Injector

General Pump 100825 is a downstream chemical injector for pressure washers and car washes with a 1/4-inch hose barb that is adjustable. It handles a flow rate of 3-5 GPM and a maximum pressure of 4500 PSI. This adjustable downstream injector is made with brass for durability and corrosion resistance.

Specifications:

• Manufacturer Product Number: 100825
• Flow Rate: 3.0 to 5.0 GPM
• Max PSI: 4500
• Max Temperature: 190°F
• Inlet Port: 3/8" NPT-M
• Outlet Port: 3/8" NPT-M
• Hose Barb: 1/4", adjustable
• Material: Brass
• O-Ring: Viton

Application:

• Car Washes
• Pressure Washing

Installation:

• Install valve with direction arrow pointing downstream. For proper operation, a control device such as a dual lance wand, quick couple nozzles, or an adjustable nozzle holder must be used to lower the system pressure at the nozzle. Warning: Under no circumstances should the system pressure exceed the maximum rated pressure of any component.

Troubleshooting:

• Injector will not draw liquid
  • Cause:
    1. Incorrect nozzle
    2. The system is not in low-pressure mode
    3. Discharge hose is too long 
    4. Chemical line is clogged
  • Solution:
    1. Check and change the nozzle
    2. Change or adjust the nozzle to put the system in low-pressure mode
    3. Reduce the length of the discharge hose or change the injector
    4. Clear chemical line of obstruction
• Rate of draw seems too slow
  • Cause:
    1. Discharge hose is too long
    2. Air leak in chemical line
    3. Chemical is too viscous
  • Solution:
    1. Reduce the length of the discharge hose or change the injector
    2. Locate and repair the leak
    3. Reduce the chemical with water to decrease viscosity
• Chemical injector is leaking from hose barb
  • Cause:
    1. Obstruction in hose barb check valve
    2. Damaged O-ring in check valve
  • Solution:
    1. Disassemble and remove obstruction
    2. Remove and replace O-ring
• Excessive pressure load on pump, motor, or engine
  • Cause
    1. Clogged injector
    2. Improperly sized injector orifice
  • Solution
    1. Clear injector orifice of obstruction
    2. Change orifice
